Most shoes have a compressive “binding” effect on the foot much like a corset around a Victorian lady’s waist.  Shoes should not force the foot to conform to a certain shape, but rather, the shoe should stay out of the way of the foot!  A foot during gait should “expand” as weight is applied spreading at the toes and balls of foot.  Shoes tend to bind this expansion thus decreasing the stabilizing potential of the foot from the ground up.  The more you bind the foot—the worse you will move and walk—it’s that simple.  Tall columns need good base of support for stability and integrity.  Narrowed feet “bound” with shoes will never facilitate optimal base of support.

Why do we bind feet with shoes?  Sex and attraction—to make the feet appear smaller or more attractive.  To improve both health and safety from the ground up–remove the foot constraints and allow the feet to expand naturally. *See my Products Section  for more information

One of the healthiest things you can do for your feet is to simply take OFF your shoes!  Many people develop foot fungus problems because they never air out and cool down their feet!  Why do people keep their feet covered?  Culture mainly—in Western culture the feet are not respected and mostly ignored until they hurt.  People with poorly functioning feet rely too much upon the shoes for support, so much of the reason for keeping feet covered is driven by shoe marketing telling us that shoes “will fix” our feet which could not be further from the truth!  While it might be difficult and even uncomfortable at first, wake up your feet by taking off your shoes at least inside your own home.  If you just can’t bear the thought of nude feet, try a special moisture wicking sock that will both keep your feet dry and cool them down.  SmartWool is a brand of hiking socks that has great wicking and cooling technology built into the fibers yet won’t make your skin itchy; however, what your feet really need is to be totally uncovered for hours per day before you ever go to bed!  *See my “Products Section” for more information.

I’m not a math guy; I always did much better in English and art…and health of course. However, when I saw the math regarding ground forces with each walking stride, even I was impressed! What I have learned is that the fastest way to make a change in a person systemically is to work with their feet and ankles. Why? So I can improve their walking gait. Do the math. It’s obvious. A simple and primary objective of mine is to get people to walk better. Do the math-you’ll see why. For people disabled in wheelchairs or walkers, I will shift up into the hands and wrists.

It all changes when the feet (or hands if using wheelchair) hit the ground! Read More »

In my ongoing quest for Foot Fitness, I was chatting with my neighbor Fernando about soccer shoes.  Fernando grew up with soccer so knows a lot about the game, coaching, and other issues related to potential soccer injuries. I was telling him about how flexible shoes are better for feet which caused him to mention the Adidas Copa Mundial soccer shoes. He told me when kids have feet problems, they put them into the Adidas Copa shoes, and nearly always the foot pain goes away! Why? Apparently the Adidas Copa is more flexible than many of the newer soccer shoes available–not only the actual soles but also the upper materials since they are made with kangaroo leather. Additionally, the cleats in the Copa are a bit shorter which is better for us in SoCal or Central California where we have much drier climates with harder grass–apparently, the shorter cleat reduces the force into the bottom of foot from what the players report.  The reviews are interesting. People swear by these shoes in terms of comfort and performance–even some Pros.

I thought the Adidas Copa soccer shoes were a good find for overall foot fitness since I have so many clients with kids that play lots of soccer.  If your child is having problems with feet, ankles, and even knees or more up above, you might consider switching to this old school shoe model that has been around unchanged since 1979. If it’s been around that long with the same design, it must be worth wearing!

“Concavity” is basically the “curve” on the bottom of the shoe along the balls of feet section as pictured in the feature photo above.  Pick up a traditional shoe.  Hold it right in front of your eyes looking down the length of the shoe from toes to heel.  On many shoes, you will likely see the bottom is concaved or “curved” with the lower portion being right in the center.  Now look at the bottom of your own foot.  You will see the natural foot is NOT concaved with a projected or pointed center, but rather, the foot is basically flat along the balls (metatarsals joints) so it can fully contact the ground and stabilize the upper body then propel the body forward in gait.  Since the balls of our feet are designed to be FLAT on the ground for stability, a concaved shoe bottom completely alters position and function of the ball of foot joints as the concavity drops the middle joints down into a hole and out of optimal position.

Behold! The Metatarsal Arch of forefoot which is curved in the opposite direction of concave shoes!

Even more interesting is what is under our forefoot skin at the skeletal level of the foot. We actually have a curve going in the OPPOSITE direction of how most shoes are designed–our upward curve is called the “Metatarsal Arch.”  This arch goes across our foot not lengthwise as with the more obvious arch on the inside or medial part of our feet. While you don’t see this Metatarsal Arch, you can feel it and see it working if you softly place your naked foot on the ground then firmly press down–as the balls of your feet compress into the ground, you will witness your foot “flattening” across the forefoot section as it widens. This part of the foot is critically important for shock absorption yet tradition shoes ruin this part of the foot’s ability to absorb and disperse ground forces! The end result is more force coming up into our knees, hips, back, etc. OUCH! This is NOT good.

Why are shoes designed with concavity?  Tradition and fashion.  Western culture places higher attraction on smaller feet–shorter and more narrow. A concave sole makes the foot appear narrower due to a “winged” effect as the edges are curled and lifted upwards while pulling outer joints away from ground.  In opposition, this “narrowed foot” is not widened like “working class” barefoot peasants.  Sex and attraction win again while feet lose.  Also note the possibility of “inside” concavity as the bottom sole surface of the shoe might be flat while the “inside” of the shoe liner can be concaved from design or from heat and pressure–this is called “creep” and will be addressed in a future post. For more information, visit my “Products Section.”

The topic of tread design on the sole of a shoe is yet another fascinating foot fact I learned from Michael Sandler, author of Barefoot Running.   You’d really have to read Michael’s book for the whole story, but basically many tread designs are for motion control purposes.  I did not realize how much motion control was built into tread design until hearing Michael’s explanation.  I thought the tread lines were just for “traction only,” but that is not the case.  Flip your standard running shoes over.  You’ll see “asymmetrical lines” on the bottoms meaning that the lines are not evenly spaced throughout the whole shoe.  The lines are likely curving to track your foot into a certain position—welcome to motion control.  After learning this, I discovered my old trail running shoes had “pivot points” built into the outer edges.  The pivot points are higher allowing the shoe to rotate easier.  While this might sound smarter than a foot—it is NOT!  Feet don’t always belong in neutral or perfectly aligned.  Depending upon terrain and condition, sometimes feet need to pronate, internally rotate, externally rotate, flex, extend, or combinations of the above.  To assume that the shoe should force the foot into a certain “optimal” position is flawed.  The motion control is in your feet—not your shoes!  It’s simple—we need to trust our feet.

In my featured photo above, both of these shoes are commonly referred to as “minimal” shoes; however, the top shoe (New Balance Trail Minimus) has a very different tread design than the shoe below (Merrell Trail Glove). What is the difference structurally? The New Balance tread is designed for traction control but not much “motion” control while the Merrell has significant motion control lines built into the tread design to “channel” feet into certain positions. The last time I looked at the bottoms of my feet, no deep motion controls lines were etched into them. If you think my older feet might be outdated models, my grandson Baby Reece is only one year old. He has got the new “updated” models, yet his feet have no deep motion control lines–some crinkled fat and nice foot prints though.

Our feet by design have traction control for better grip–but the nerves in our feet working in unison with our brains are the natural motion control–NOT shoes! Keep it simple–trust your feet first.

“Minimalist” shoes are “supposed to” mimic barefoot function, but don’t be fooled because some so-called “minimalist” shoes are not exactly minimal.  Just because a shoe has a thin sole that is flexible does not make it a “true” minimalist shoe—even though the shoe companies want you to believe the marketing pitch.  If the shoe has a motion control tread design—it cannot truly be a minimalist shoe. The shoes featured in the photo ARE minimalist shoes–none of them have significant motion control built into tread design or other parts of the shoe. Their soles are designed for traction–but not motion control. Big difference.

• Here’s a tip to expose minimalist shoe “impostors” because a true minimalist shoe will let the foot do the work—even with tread design.  To determine motion control tread design, turn shoe over and look at bottom surface.  If you see tread patterns flowing in “lines” that seem to guide the foot in a certain direction—this is motion control.  Your tread pattern should be symmetrical and for general traction—not “asymmetrical” and forcing the foot back into a certain line or position.  Note that it is not healthy or safe for the foot and ankle to “always be in neutral” depending upon the environment, ground angle, slope, etc.  Let the foot decide position—not the shoe!!!  If the shoe has motion control tread design, heel cup support, toe box support, a heel lift, or other “bolt-on” engineering that is trying to support the foot or alter its shape and position, it is not a true minimalist shoe.  The foot needs to function as close to bare as possible—that is true minimalist shoe design—not hype. 
• While there are dozens of new minimalist shoes coming out on the market to take advantage of the barefoot running trend, just know that they are not all created equal and most definitely are not all true minimalist shoes.  To some degree, many of these new shoes are still trying to control the foot instead of getting out of the way of the foot, so don’t be fooled by foot foolishness through marketing because your foot knows the difference!

So know you know “the rest of the story” beyond the hype marketing with shoe companies.  For more information, see my “Products Section.”  I would also HIGHLY recommend reading “Barefoot Running” by Michael Sandler of RunBare.com if you really want to learn the details beyond this post. Great read that applies to running with minimalist shoes as well as barefoot.

The “Prehensile Foot” is an interesting term that was completely new to me after 13 years of college and two decades in the fitness and health business until a couple years ago.  Defined, “prehensile” means “to grasp.”  Toes are basically designed to grasp the ground and assist in balance and throughout the gait process.  Talk to any good martial artist about “root” or base, and they will tell you about the importance of the feet to screw into the ground—or root—rip and grip, or something to this effect.  Don’t underestimate toe power!  One of the best things you can for both health and safety is to let your toes do their job—grasp!  Most shoes basically ruin our ability to grasp with toes because they are too narrow and/or too short.  Over time this alters the shape of the foot and removes the “prehensile” qualities. *See my “Products Section” for more information.  

From a standing or static stance position, it’s really very simple.  Let’s establish a “baseline posture” and start with standing in one spot—without movement.  We can look at an anatomical model of the foot and clearly see how and where the foot wants us to distribute weight.  By bone design, the larger surface areas along bottom of foot resemble that of a tripod.  The most obvious area to place weight is on the heel bone called the calcaneus (1).  Another bone region with extra density and larger surface area is behind the big toe—the first metatarsal joint (2).  The last leg of the tripod is along the lateral border near the outside balls of the feet—in particular the “Base of Fifth Ray” (3) area has some unique weight distribution capabilities that get completely altered when we wear heel-lift shoes because this important area gets “lifted” up and away from ground contact thus compromising our structural “tripod” of support. The Base of the Fifth Ray is fascinating! Most people have never heard of this important part of the human foot! *See my Foot Products section for more information.

The notion of “trim ankles” for attractiveness translates—weak ankles!  Ankles that have been immobilized from high heels limit the amount of muscular work and range of motion causing the ankles to appear “trim” or thin.  While some might find that attractive, it’s not a good system for supporting a tall vertical column and transferring large amounts of force for humans.  How do you get strong ankles?  Use them.  Wear shoes that allow for full range of motion in the ankle and Achilles due to minimal or NO heel lift.  Wear shoes that don’t artificially support the ankle, but rather, challenge the ankle to stabilize i.e. WORK to maintain vertical column integrity.  *For more information, see my Foot Products section.
