Wear Flip-Flops in the Shower
If you shower in public places, like the pool or your gym, you're exposing your feet to millions of bacteria crawling on the floors, waiting to attach themselves to the underside of your feet. A comfortable pair of self-draining flip flops, such as UA Locker Slides Special Edition ($20, underarmour.com) acts as a barrier between your feet and the floor. Most shower sandals are lightweight and compactible, so they won't weigh your gym bag down. Slip them on before walking through the locker room, or upon exiting the pool.
