Foot Lube
You runners know what this is, and the rest of you -- or at least your toes -- will be thanking us. A silicon solid that goes on like a mini-deodorant stick, foot lube like the Profoot Care Slik Stik, Anti-Blister Stick makes your toes and heels slidey, but not slick. It's just enough to keep straps from biting and heels from chafing. Small enough to fit in your bag, and cheap: $5.59 at Drugstore.com. (Photo: Drugstore.com)
