I Spent 30 Days Strengthening My Feet — And It Changed How My Whole Body Moves

Biceps, quads, abs, glutes (and yes, extra emphasis on the glutes)—these are the muscles that take up the majority of our mental real estate. We track them, obsess over them, build entire training blocks around them.

But what about your flexor digitorum brevis? Your quadratus plantae? Your plantar interossei?

Okay, I'm being slightly facetious. But it is true that we almost never think about the muscles of our feet. There are 29 of them, small and intricate and working constantly underneath us, and for most of us, they're a complete afterthought. We ice our hamstrings, foam roll our IT bands, and spend entire sessions dedicated to shoulder mobility. And then we slide on a pair of narrow-toed sneakers and call it a day.

Your feet are the first point of contact between your body and the world. Every step you take is a neurological and muscular feedback loop; your brain is constantly communicating with the thousands of mechanoreceptors on the soles of your feet, processing where you are in space, how to distribute load, and how to keep you upright. It's happening automatically, all day long. It's easy to take for granted.

What's less easy to ignore is what happens when that system starts to break down.

Courtney Conley, M.D., a chiropractic physician and one of the leading experts in foot and gait mechanics, echoes these same points. She explains that declining foot strength correlates with reduced gait speed, increased fall risk, and a loss of independence as we age. These aren't just orthopedic concerns. These are real, measurable outcomes that start accumulating long before most people think to pay attention.

I started using them in the evenings, usually while lying on the couch watching TV. And wow, the first few times, they were uncomfortable. Not painful, but just a very unfamiliar feeling, especially after years of sports and long-distance running. 

Around that same time, I saw an Instagram video showing the feet of a few elite athletes, and it was a little alarming. Their toes were visibly compressed and crowded from years of high-impact training and narrow footwear. And although I’m not an elite athlete, I do not want my feet looking like that in a couple of decades. 

This sounds more intense than it is. Mostly it looked like slow calf raises with an eccentric focus (the lowering phase is where the real work happens), short-foot exercises, some very humbling attempts at independent toe movement, and barefoot balance drills. 

I do love a good slipper, so this was not a sacrifice I made lightly. But the goal was to give my feet more time to engage directly with the ground—to activate those intrinsic muscles instead of letting them idle inside (my very cute) cushioned mule. 

I then took a close look at the shoes I was wearing every day. Not the occasional heels or one-off outfits, but the shoes I actually lived in—my walking shoes, my training shoes, the ones I wore for hours at a time. I started paying attention to the shape of the toe box, the amount of cushioning, and the overall structure. And what stood out most was how much modern footwear prioritizes comfort in a way that can reduce function.

Conley explains that highly cushioned running shoes dampen the sensory input from the mechanoreceptors in your feet, reducing proprioception and creating a less stable platform. Your brain gets less information about where your body is in space. 

Under load (like during a squat, a lunge, a lateral cut on the pickleball court), that reduced clarity creates micro-instabilities that travel upward through the ankle, knee, hip, and spine. Over years and decades, that accumulates. I'd written about this at length in a piece for Well-Being Forecast on the rise of training shoes; you can read a much deeper dive into the biomechanics there, so I knew what I was looking for.

With that in mind, I decided to experiment with a few different types of shoes.

The first pair I tried was the Astral TR1 Sensi HT. I didn't realize how narrow my other shoes were until I put these on. The wide toe box sounds like a small thing until your toes have actual room to splay, and then you wonder how you've been walking around in the other shoes for so long. 

They're zero-drop, made with natural fibers, and designed to maximize ground feel without completely removing support. I started using them for walks, errands, and lighter training days. A word of caution: if you've spent years in heavily cushioned shoes, don't go straight to zero-drop everything overnight. I transitioned gradually, adding more time in these week-by-week, which let my feet actually adapt.

The second was while on earth's move trainer, which I wore on days I was more active. This shoe features a wider toe box—which, after spending time in the Astrals, I now notice immediately—and a 6mm heel-to-toe drop, so it's not fully zero-drop but still pretty minimal. There's slightly more cushion here than the Astrals, which I actually appreciated on higher-impact days. And even though it is designed more for gym and training use, I ended up reaching for them not only on workout days but on plenty of walks, too.

After a month of paying attention to my feet in a way I never really had before, the changes weren’t dramatic, but they were surprisingly noticeable. I felt more stable during single-leg exercises, especially things like split squats or RDLs, where balance matters more than you realize. I also noticed less foot fatigue after long walks, runs, or pickleball sessions. And during heavy lifts at the gym, I felt stronger, in more control, and connected to the ground 

But the biggest shift was awareness. I became much more conscious of how I was standing, how I distributed my weight, and how much my shoes played a role. I felt more grounded, more connected to how I was moving, and quicker to adjust when something felt off.

We spend so much energy chasing the visible—the muscles we can see in the mirror, the aesthetics, the numbers on the bar. Which isn't wrong. But the foundation underneath all of it is 29 small muscles, 26 bones, and a feedback system that's been largely ignored.
