Whether your training consists of a bodybuilding split-type schedule, you're training for a sport (basketball, weightlifting, powerlifting, etc.), or you're just doing total body workouts to get stronger, you might be forgetting some of the most important muscles in your body.
When you do any type of exercise, whether you're running, jumping, performing a deadlift, or throwing, it all starts with your point of contact to the ground. Your feet are your foundation, and, therefore, training your feet, or training barefoot, will build a rock solid base of support equipped to handle any task.

Barefoot training has slowly started to make its way back into the mainstream media. Five-finger toe shoes or other types of minimal shoes have been touted as the "optimal" footwear for runners everywhere. I'll be the first one to admit that those toe shoes look absolutely ridiculous. Despite their horribly unfashionable nature, I do believe that barefoot training is an excellent addition to any training protocol.
There are plenty of naysayers in the minimal footwear movement: many people say that barefoot training can actually cause more harm than good. First of all, humans have been performing great feats of athleticism long before Nike was telling us to "Just Do It." In fact, we were "just doing it" with no shoes or maybe thin sandals that would protect our feet from sharp objects or hot sand. We were climbing trees, running away from wild boars, walking back to camp with livestock slumped over our shoulders, and climbing mountains without buying specialized footwear for those tasks. There are numerous civilizations today who are still doing all of those aforementioned tasks without the help of sneakers. Instead, those people have learned to harness the power of their own feet.
Now, I'll step away from the more anthropological talk and shift more into physiology. First, let's discuss the term "proprioception." I've mentioned this term in my blog before, but for those of you who don't remember, proprioception refers to "the sense of the relative position of neighbouring parts of the body and strength of effort being employed in movement," as per Wikipedia. Proprioception helps you adjust to uneven surfaces, understand how much pressure you're applying to said surface, among other things.
Shoes can limit the proprioceptors in our feet. Although your feet are proportionally small in comparison to other parts of the body, each foot has about 20 muscles, 26 bones (about 1/4 of the bones in the body), 33 joints, and over 7,500 nerve endings! Think about that: such a small part of your body includes a quarter of the bones in your body! Now, if you're cutting off the proprioceptors in your feet, you're cutting off a very sensitive and responsive area of your body.
One study done at the German Sport University of Cologne measured the activity of several muscles in and around the feet using Electomyography (EMG) while participants walked on grass barefoot, using minimal footwear and in traditional running shoes. They found that
I have cited several other studies in the Works Cited below, if you're interested in reading more into these studies."The use of minimal footwear was related to changes in musclestrength and morphology. It was demonstrated that thefootwear increased mechanical stimuli on the tendon muscleunits. The muscle strength capacity of those muscles whichwere more intensively used by the minimal shoe increasedsignificantly. Muscles which were similar activated in bothconditions did not respond. One can conclude that footweartechnology impacts the mechanical loading as well as thebiological response of the loaded tissues. "
While many of these studies involve running/walking, I believe that barefoot training carries over into lifting as well. I will have my clients roll out their feet with a golf ball or lacrosse ball before exercise. This will improve the sensory input and also improve their range of motion. Try this: Stand with your feet together and try to touch your toes. Now roll your feet out for about 5 minutes and then retest. You will notice that you are more flexible afterwards.

I will also have them do their activation/warm-ups barefoot; single leg RDLs, high skips, Bulgarian split squats, kettlebell swings, etc. can be done without shoes. Deadlifts are also an excellent exercise to try barefooted as well. You can see what you're doing with your toes: are you flexing your toes or "gripping the ground?" These actions are not ideal and should be corrected.
Now, if you want a great brand of minimal shoes that don't look absolutely obnoxious, I'd recommend the brand Inov8. Their shoes are comfortable and pretty sexy (in my opinion), and I'm absolutely obsessed with mine! There are several other minimal brands out on the market, so find a pair that you like!
If you're looking to get the most out of your training and avoid injury in the process, try taking your shoes off whenever you can. It feels pretty nice to let your feet spread out and breathe a little bit!
