Calluses. Hard, thick skin on the bottoms of your feet (aka: calluses) and thick bumps around the perimeter (usually corns) have many causes, but usually ill-fitting shoes or frequent repetitive motions such as running that cause friction between your bones, skin, and shoes, are to blame. While an overly-callused foot can be unattractive (and corns can become uncomfortable if they get too big), some callusing is a good thing — it helps form a naturally protective barrier between your foot and the ground.
The Solution: If your calluses are on overdrive, the easiest way to remove them is to get a pedicure — yes, really. Professional salons have all the tools to make skin-sloughing fast and painless. For an at-home approach, soak your feet in warm water for 10 minutes (you can also do this in the shower). The warm water softens tough skin and makes it easier to remove. Next, use a pumice stone (Tweezerman Two-Sided Pumice Stone, $8, tweezerman.com) to firmly scrub back and forth across the callused area.
