Being barefoot and running barefoot is a blissful and consciousness-expanding endeavor. The feedback supplied from the ground is powerful enough to force even experienced runners to try it for only a mile or so, if they make it that far. Barefoot running, however wonderful, should not be subscribed to dogmatically.

There are myriad resources available expounding on the benefits of being barefoot. Most of their reasons, methods, and warnings have merit. Unfortunately many of them sway to heavily towards the one-size-fits-all solution.

Experiencing life unshod isn’t always the best option. Putting on a pair of huaraches or other minimalist shoes can serve a number of beneficial purposes:

1. Technical Trail Running.
   Many people worry that the rocks, twigs, and roots on a trail make barefoot trail running impossible. Not true. First, you use your eyes and avoid what worries you. Second, your feet aren’t rigid and can grab and grip and mold around many “obstacles.”

   That said, while there’s nothing better than feeling the grass beneath your feet, having your heel land on an embedded rock leaves something to be desired. To be more specific, it could leave behind a bruise that will take at least a week to heal.

   That doesn’t include the chance of damaging the fatty tissue which protects your heel bone from impacting the ground. If any of this sounds painful, trust me, it’s worse than you’re picturing.

   A trail has hazards which you may not wish to risk if you’re still an inexperienced barefooter. When a single false step means a week of no running, it’s just not worth it to be ideological about keeping yourself unshod.

2. Additional mileage
   Your body may be able to take additional mileage, but the bottoms of your feet may not be ready to support it yet barefoot. Now, if you’re looking to become a better barefoot runner, this is good news — when your skin tells you to stop… STOP! Over time it’ll adapt (not callous) and you’ll be able to put in more miles.

   Until then, there’s nothing wrong with protecting your precious footsies, but only if you know your form is correct. If you are transitioning from shoes to barefoot and have yet to perfect the change from heel strike to mid foot strike or a forefoot strike, don’t ask for trouble by adding more miles in a minimalist shoe. You’ll find yourself injured promptly and thoroughly.

   If you are comfortable in your stride, you will find that your feet hit a natural point where further barefoot running may only lead to blisters (that usually means your form has broken down and you’re pulling/pushing the ground, instead of placing/lifting). In these cases, adding a protective covering will give you the opportunity to add those additional miles you crave.

3. Racing
   A foot covering increases your margin for error while running. Proponents of barefoot running tout the pain feedback loop as a beneficial aspect. Any foot covering blocks the pain receptors, which allow you to cause more damage to your body.

   In a race, this can be a necessary evil. A reduced pain feedback loop allows you to run a longer duration of more intensity. The covering may also absorb some of the mistakes you may have made barefoot (stepping on that rock in your mental fatigue).

   There’s obviously a very fine line to be ridden here, and one that you can certainly go too far with. Go with the least amount of covering possible and you should be able to dampen and absorb just the minimal amount of error to improve your results.

   I’d love to say, “If you’re not comfortable running that distance, don’t race that distance.” But I know how some of us… I mean, YOU… can be

4. The bitter cold
   Mother nature yields to no man. Don’t even think about getting the best of father winter.

   If you live in a climate that has a true winter, you know what frostbite feels like. Now try running barefoot.

   Amazingly, there are folks who do it, and enjoy it. And check out Steven shoveling snow in his huaraches. Frankly, I’ve tried it and even I think that’s crazy. Most people are going to need something to keep their feet protected from the elements (wind, snow, slush, etc.). Each person has a different tolerance, which will adapt as they get more comfortable with the colder weather.

   When dealing with the elements it’s best to be safer than pull up limp 3 miles from your house and walk the rest of the way home.

Barefoot In the cold

Here in the Northern Hemisphere, Winter is upon us. And people email me every day asking what to do if they want to be barefoot or minimalist in the cold weather. While I’ve written about running bare foot in the cold before, this is a whole new thing

First let me say: DO NOT TRY THIS AT HOME. In other words, don’t go out and try to imitate me.

I’ve been barefoot running for over 2 and a half years, and haven’t worn a pair of real shoes for more than a total of 3 days in that time. 

Last winter, I thought, “I’ll keep my Invisible Shoes on until it seems too cold.” And the next thing I knew, it was Spring!

So, clearly I’ve acclimated. And that’s not too surprising. Humans (and our hominid cousins) lived in cold climates without shoes for a LOOOONG time. So, we’re kinda wired for it, if we give ourself time to adapt.

Here’s the video I just shot, after we got 18″+ of snow in Boulder. It’s about 15 degrees out.

What I did is this:

• Outside for about 10 minutes
• Inside to dry off my feet and warm them for 5
• Outside for another 10
• Inside to dry and warm for about 3
• Outside for 30+ minutes… by this time my body temp had gone way up. I was sweating quite a bit. And my feet felt totally warm. Not numb. Warm. When I got inside after finishing the shoveling, they didn’t have to thaw or warm up or anything.

Lena wants me point out that you should check the Wiki about frostbite so you don’t do something stupid and get hurt

Invisible Shoes wins Best Huaraches Running Sandal 2011

Christian Peterson, better known as The Maple Grove Barefoot Guy, just announced his first ever Grovie awards for excellence in minimalist footwear.

And we are thrilled to announce that Invisible Shoes won the Best Huarache category.

Here’s what Christian had to say:

2011 was really the year of the huarache.  We saw tons of new sandal companies crop up, all with great new innovative designs.  The big two companies (Invisible Shoe and Luna) also put out some great updates to their original models.  But Invisible Shoes took that innovation to the next level.  They went out and got a former Nike shoe designer to make the FeelTrue sole of their Connect and Contact huaraches.  The result is a powerhouse of a sandal that has no real apparent weaknesses.  

Christian recently reviewed the Connect and Contact version of Invisible Shoes, so we’re especially honored to have 2 mentions in such a short period of time.

That said, while we’re happy to have won Best Huaraches running sandals, we have LOTS of plans for even more improvements and additional products for 2012. I hope that in next year’s Grovie Awards we win at least two categories, maybe even three!

2011 has been a big year for us: Releasing the only outsoles made specifically for barefoot running (some like to say “bear foot running”) sandals  that were designed with the help of former lead designers from Nike and Reebok, our 2nd Anniversary, and a HUGE upsurge in business.

Between you and me, every time I see Chris McDougall, I practically kiss his feet. If it weren’t for him and the success of “Born To Run,” this whole barefoot running trend may never have taken off.

So, thank you again to MGBG, and to everyone else who has helped us and supported us in 2011.

I can’t wait to hear the comments when we launch all our new barefoot running sandal products in the next year.

As the barefoot running boom continues to explode, it’s important that we debunk the mythology that’s sprung up and face some facts. And perhaps the most obvious fact is this:

If you run with anything between your skin and the ground, you are not barefoot runner.

Let me say that again. If you wear Vibram Fivefingers, New Balance Minimus, Merrell Trail Gloves, Altra Adams, Vivobarefoot shoes, Newtons, Inov8 shoes, even our Invisible Shoes huaraches running sandals, you are not a barefoot runner.

I don’t care if your previous shoes were padded stilts and your new shoes are a “zero-drop” natural movement minimalist shoe, if you’ve got something on your feet you’re not barefoot running.

Barefoot running means that you run in bare feet. Period.

Now, don’t get me wrong, I’m not saying that if you’ve just spent $125 on your Vibram Bikilas you need to throw them away, or that if there’s a barefoot running Meetup you can’t be part of the cool clique. And I’m not saying everyone needs to be barefoot. And, clearly, I’m not saying “don’t buy Invisible Shoes”

But it’s important that we differentiate actual barefoot running from minimalist running.

Why?

Because more often than some would like to admit, barefoot running and minimalist running do not produce the same results.

The promise of barefoot running is that the sensations you get when your skin contacts the ground — often known as pain — teach you proper running form. That is, if you change your form to make the pain go away, you’ll have a more efficient, lighter, easier stride, and you’ll be able to run pain-free for life.

Anything that you put on your feet reduces the amount of sensation you feel and can interfere with the feedback loop that barefoot running gives which produces those benefits.

Again, I’m not saying that you don’t get feedback from minimalist shoes. You certainly get more than you do when you’ve got 2″ of padding in your  Nike I Can’t Feel The Grounds. As the developer of Invisible Shoes, I know hundreds of people who switched to our sandals, improved their running  form, eliminated life-long aches and pains, and now enjoy running ultra-marathons. As one of our early customers put it, “Invisible Shoes are just like being barefoot… if they covered the world in a thin layer of comfortable rubber.”

But, I’ve also met a LOT people who bought a pair of Vibrams or Merrells (or any other minimalist shoe), soon became injured, and now tell everyone they know that “barefoot running” is dangerous… and they’ve never run barefoot!

I’ve been on a number of barefoot running panel discussions and, inevitably, there will be some number of doctors, physical therapists, podiatrists and other medical professionals who say, smugly, “Hey, stick with this barefoot running thing. All the people getting hurt by doing it are putting my kids through college!”

Before they can finish chuckling, I fire back:

Me: “You know, of course, that all you guys made the exact same joke 40 years ago when running shoes were invented, right? And you know that people who have no problems running barefoot — and ones who get cured of injuries by running barefoot — will not come to see you, right?”

Them: “Uh…”

Then I pull out the bigger guns: “And when a patient tells you they got hurt from barefoot running, did you ask if they were actually in bare feet? Did you check to see if they simply over-trained by doing too much, too soon? And, maybe most importantly, did you take a video of them running so you could analyze their form and see if they were simply using the same injury-producing mechanics they used when they wore shoes? Or did you see if they were trying to stay on their toes, putting extra strain on their calves and Achilles, because they have a mistaken ideas about proper barefoot form?”

Them: “Uh…”

Barefoot running is more than switching to a minimalist shoe. And it’s more than simply removing your shoes. Don’t believe me? Go to a barefoot running event, find the people in their minimalist shoes, and see which ones are still landing on their heels, as if they’re still in motion controlled running shoes.

In fact, be on the lookout for runners who are actually barefoot doing the same thing! Some of us are either unable to feel those important form-changing sensations, or unable (without coaching) to actually make form changes in order to find a painless way of moving.

For an example of this, check out Pete Larson’s video of the recent NYC Barefoot Run. Most of the VFF wearers, and a handful of barefoot runners are still landing on their heels. (I was there and noticed the same thing, but I didn’t have the brains to video tape it… so, Thanks, Pete!)

Let’s wrap this up with a wish: If you’re one of those “barefoot” runners who has never run barefoot, I can’t encourage you enough to try it. Don’t think there’s some transition you need to go through before you’re “ready.” Ironically, the best advice I can give you is: Just Do It!

Get on a good clean hard surface (a bike path is great, streets work too) and go for a run. Listen to your feet, if they hurt, try to move in some different way so that they don’t. And if you can’t figure out how, then stop and try again another day. Don’t think you need to build up callouses; none of us who successfully run barefoot have any (they’re another sign that you’re doing something wrong). If you can find a coach or some training, get some guidance.

Report back here with what you discover.

The goal is not to be barefoot all the time. The goal is to be flexible. To be able to run comfortably, easily, and enjoyably under any circumstance. To know when barefoot is the best option and when something under your feet is called for. I wear my Invisible Shoes for all my walking, hiking, and getting into restaurants. I’m barefoot for a lot of my sprinting training. But, hey, I still wear running shoes, too… when I have to shovel a 2′ Colorado snowfall.

Jordan Flowers just posted his review of Invisible Shoes and often mentions “other huaraches”, without mentioning names… but it’s kind of obvious who the comparison is to if you’ve been looking at huaraches.

I must say that I’m thrilled to see someone independently discovering what we’ve been saying for 2 years

Enjoy his review of Invisible Shoes here.

Oh, the joys of being barefoot. We will all be able to look back and think of this time as “the enlightenment” when we finally ditched our constrictive foot coffins and let our toes emerge, shaking and crooked, to see the light and heal. The more you adjust to ditching the shoes, the more you find yourself heading out shodless or in something minimal (not everyone wants to get kicked out of a restaurant or pay attention to every shard on the street).  Unfortunately, this pedal liberation does have its costs. You may now find yourself struck with a case of shoeguiltitis (SHOO-gilt-ite-iss).

The Problem:

This affliction generally creeps on slowly, but as you embrace your barefoot life more fully, you may quickly and unknowingly find yourself in its grips. Do you avoid looking at the piles of shoes in your closet? Do you find yourself making negotiations when passing the shoe rack? Oh, I will wear them next week. But next week never comes. Do you feel regret and see $$$ signs oscillating through the air when confronted with your shoe collection? Do you suppress a strong urge to hurl all of your shoes out the window and into the nearest dumpster? Then feel the inevitable guilt for the landfill waste you would be contributing to as well as the hundreds of wasted dollars spent? Do you feel the urge to run with your old shoes only so you can get your “money’s worth” and use them until they are “done”? If you have answered yes to one or more of these questions, you have Shoeguiltitis.

The Solution:

Fear not, my barefoot amigos! While you have moved on from your raised-heel, toe-spring, arch-supportive motion-control running  shoes, there are others that will find hope and safety in your shoes. Soles4Souls can take your old shoes, clean them up, and donate them to those in need. I know what you’re thinking – why would I want to give someone else the very shoes that had me feet up with two bags of frozen peas on my knees? Here’s why: in other countries where clean water isn’t as plentiful and infectious disease isn’t as easily controlled, there are children and adults who can protect themselves from sickness and disease by wearing shoes. For others, they may have access to clean water, but may have lost everything they own due to devastating circumstances. You can make a difference.

Soles4Souls was founded on the mission to “change the world, one pair [of shoes] at a time.” After seeing the devastation of the 2004 tsunami in Asia and later damage inflicted by Hurricane Katrina, CEO Wayne Elsey felt compelled to do something. When television coverage aired a single shoe washing up on a beach, he knew he had found his calling. From there S4S was formed and has since donated well over 14 million pairs of shoes to 127 countries including Kenya, Thailand, Nepal and the United States. Every 7 seconds, a pair of shoes is placed into the hands of someone in need. Soles4Souls is a 501(c)(3) organization recognized by the IRS and donating parties are eligible for tax advantages.

Feel the World!

I don’t get starstruck, but I do get excited when I meet someone who’s work I’ve admired and appreciated for years. And Phil Maffetone is one of those people.

I got my copy of Phil’s book In Fitness and In Health in 1997 and, way back then (even earlier, really), he advocated minimalism and barefoot running. Reading his books almost made me want to switch from sprinting to marathons.

So, I was thrilled when Phil responded to my email asking if he wanted to try a pair of Invisible Shoes, even more thrilled when he said yes, and ecstatic to read his review at Zero-Drop.

It starts with a sentence that could put a chill in the heart of any shoe maker:

I don’t like writing shoe reviews, because I don’t like many shoes.

But it happily and quickly leads to something we’ve heard from thousands of customers:

I slipped them on — easy enough. I walked, jumped, and ran. It was an all around pleasant surprise.

Phil is smart enough not to overdo it in a new pair of shoes, but like many who enjoy the feeling of being able to Feel The World, he couldn’t help himself and went out for a 20 minute spin.

If you don’t know Phil, you have got to check out his writing (and his music!). A true pioneer in the fitness, running and health world.

Thanks, Phil!

Here’s a quick video showing you how to measure your feet and get the correct size for your Invisible Shoes.

A major advance for barefoot sandals

We are extremely proud to introduce you to the only outsole specifically designed for barefoot running, our new FeelTrue™ outsoles.

With the help of one of the world’s top outsole manufacturers, and former lead designers from Nike and Reebok, we started with the famous Vibram Cherry material (that we’ve been happily offering since November 2009) and made these improvements:

• Contoured to fit your foot, without providing unnecessary support
• “High-abrasion” material lasts a long time
• Very flexible (great barefoot feel) while still providing strong protection
• Holds it shape better
• Slight “toe spring” keeps the sole closer to your foot
• Sized for feet from 5″ to 13″ long — many people can use the outsole without trimming! (and there’s less waste if you do)
• Elegant shape with subtle arch and heel cup
• Easily customized with just a pair of kitchen scissors
• Topsole pattern feels soft while providing traction
• Reinforced, extended, and elevated ankle holes keep lace from wearing out
• Dual-Chevron tread pattern provides traction under any condition
• Material includes some recycled stock

There are two models of our FeelTrue™ outsole:

1. 4mm thick Connect — the closest thing to barefoot. Extremely light weight (men’s US size 9 weighs ~3.7 ounces)
2. 6mm thick Contact — still a great barefoot feel, but with more protection. Slightly stiffer, but still flexible. (men’s size 9 weighs ~ 5.3 ounces)

Whether you walk, run, hike, or use your Invisible Shoes for anything else, we can’t wait for you to try Connect and Contact and let us know how much you enjoy being able to Feel The World™.

Amanda Novak has a new tying style, based on her Chaco sandals.

The Maple Grove Barefoot Guy shares his review of Invisible Shoes (and his AWESOME fashion sense) at http://maplegrovebarefootguy.blogspot.com/2011/04/invisible-shoe-custom-huarche-review.html

My favorite line would have to be “these are definitely my favorite huaraches so far.”

The only time I’ve worn anything other than my huaraches or my sprinting spikes in the last 16 months has been the 3 times I put on my old running shoes… so I could shovel snow.

Those shoes have my $200 orthotics in them. And each time I’ve put them on, I have the same thought, “Geez, my foot can’t even move. How did I wear these?”

Often, when I’m out and about, someone will see my Invisible Shoes and say, “Those look great, but I can’t wear them. I need orthotics.”

“I used to think the same thing,” I reply. “But let me ask you something. When has putting a cast on a limb and immobilizing it made it stronger?”

“Well… never,” they say, not wanting to admit the obvious fatal flaw in their reasoning.

“Right. So you put a cast on your foot, called an orthotic, it gets weaker. Then you need a new cast to handle how much weaker you’ve gotten, and then… Oh, by the way,” I mention, “you had your orthotic made while you were standing on a flat surface, didn’t you?”

“Yes.”

“Look at the shape of your shoe. Is it flat?”

“Uh… no.”

“Because of how the shape of the shoe influences the way you move, you really need a different orthotic for each shoe. And it needs to be fitted based on how you move in that shoe, not how you stand, motionless, on the ground.”

“Hmmm…” I can see the glimmer of realization in their eyes.

Well, now I have new ammunition in my anti-orthotic holster, an article in the New York Times by one of my favorite science writers, Gina Kolata: Close Look at Orthotics Raises a Welter of Doubts

Let me give you a few highlights:

Shoe inserts or orthotics may be helpful as a short-term solution, preventing injuries in some athletes. But it is not clear how to make inserts that work. The idea that they are supposed to correct mechanical-alignment problems does not hold up.

Kinda sums it up, yes? Just wait, there’s more.  Gina interviews the top othotics researcher, Benno M. Nigg, who says this about a man named Jason’s flat feet:

There is no need to “correct” a flat foot. All Jason needs to do is strengthen his foot and ankle muscles and then try running. without orthotics.

Who knew? Well, *I* did… I’ve had really flat feet my whole life… until I started running and walking barefoot. Now I have some arch in my foot. BTW, I’m legally required to say that barefoot running shoes and sandals are not a medical treatment, I’m not a doctor, nor am I able to promise that by going without shoes you will develop arches in your feet. That said, do some Googling and you’ll hear a lot of similar stories. Do with that what you will.

Sometimes people with high arches give me the same story. “I need support because my arches are so high.” Just because they’re high, doesn’t mean they’re strong, especially if you’ve been supporting them all your life… remember the cast analogy.

Now I’m not going to say that orthotics don’t do something. But the question is: What do they do? How do they  do it? And are they really helping.

Dr. Joseph Hamill responds, in Gina’s article:

I guess the main thing to note is that, as biomechanists, we really do not know how orthotics work.

Results from his studies cause Dr. Nigg to add:

There was no way to predict the effect of a given orthotic.

Hey, I’m not here to make anyone throw away their high-priced foot supports. Even though I haven’t worn mine in well over a year, nor can I conceive of a time I’ll ever wear them again, I can’t bear to toss mine away yet.

But I am here to inspire a bit of wondering, a bit of curiosity, a bit of common sense, and a bit of critical thinking.

Man lived without orthotics for a LOOOONG time. That doesn’t mean they couldn’t have benefited from them. But it means they got along without them. Maybe you can too. It doesn’t cost much — it time or dollars — to set up an experiment for one.

David Csonka says it best:

And the actual running, well it feels like something between being barefoot and wearing Vibram Five Fingers

Invisible Shoes fan Dan Bright teaches at a performing arts high school in Florida. And after he came into class wearing his Invisible Shoes, the students wanted some for themselves.

So we sent materials for about 24 students, and they had a huarache-making party.

Read about it here: http://www.heraldtribune.com/article/20101125/ARTICLE/11251052?p=1&tc=pg

(and if you know of a group that would like to do the same, let me know)

Want to make your own barefoot running sandals and hang out with other cool, smart people?

Then check out the Hacker Dojo huarache making party!

More details at http://events.hackerdojo.com/event/333001-shoe-making-party

“Barefoot Ted” sells a running sandal he calls the Luna Sandal. It’s similar to our custom-made Invisible Shoes, but with a few key differences:

1) Did you know there are 18 different types of “size 9″? Rather than pick just one of those and pre-make our sandals, the custom-made Invisible Shoes are, actually, custom-made for your unique foot. We use a tracing of your foot to make sure the length and width are correct for your specific foot — and if your feet are different sizes, you get sandals that match. We make sure that the toe and ankle holes are placed correctly based on the size and length of your toes and heel. With Invisible Shoes, you’re getting a product made just for you.

2) We use the 4mm Vibram Cherry sole material to give you the optimal barefoot feel, and for your convenience. Aside from really being able to connect with the ground with our soles, you can roll up Invisible Shoes and keep them in your pack or pocket — go out barefoot, and come back with some protection on your feet. The thicker 6mm sole in the Luna is comparatively rigid and over 60% heavier… add some glue and a leather upper and you’re further minimizing the minimalist feel.

3) We use soft, durable nylon/polypro laces that don’t stretch or contract when they get wet and dry out, unlike leather or hemp. Our laces are round, meaning that there are no edges to rub on your skin. Nylon/Polypro is a very strong material — I’m still using the original laces in my 12-month old huaraches that I wear every day — and after getting wet, nylon laces dry really fast. And with round laces, you don’t have to worry about “which side is up” or getting them twisted when you use the different tying styles (some of the clever tying variations people have developed require round laces. Plus, you can get our laces in a bunch of fun colors. And if you ever want to replace your laces or get other colors, they’re inexpensive.

4) Our product is “vegan friendly”. So is Ted’s basic Luna Sandal if you get the hemp laces instead of leather.

5) Luna Sandals have an optional leather footbed. Ted is making a fine product… some people like the leather upper — which, over time, molds somewhat to your foot. Any material upper, though, will wear and collect dirt. And, for those who are sensitive to these kinds of things: natural materials are not anti-microbial. While we don’t currently offer a material upper, we have heard from a couple customers who bought some leather and glue and added those to their Invisible Shoes for only a couple of dollars.

Hope that helps.

Many people wear the Vibram Five Fingers shoe for minimalist running… how does it stack up against the huarache running sandal?

Well, this video has some of my thoughts about the two.

Enjoy.

About once a week I get a call or an email from someone who asks, “Can you run in Invisible Shoes for long runs?”

I usually point out to them that the Tarahumara are known for running ultra-marathons in huaraches, so, Yes.

But some people respond, “Sure, but I’m not a Tarahumara Indian.”

True (but not necessarily relevant).

So, how bout a hometown boy who just ran in his Invisible Shoes huaraches… for SIXTY-EIGHT MILES!

Here’s a picture from Barefoot Jason Robillard after his run:

Raymond Mack devised a “thong-style” method of tying huaraches running sandals. I haven’t tried out the tying method yet, but this video makes me want to go to the beach

Fitness Guy, Al Kavadlo, emailed me today to say, “I gave the Invisible Shoes another mention in my blog today.  I really love them!”

Here’s Al running across the Williamsburg Bridge (between Manhattan and Brooklyn) in his Invisible Shoes huaraches running sandals.
