During jogging or running, the 26 bones, 33 joints, 112 ligaments, and a network of tendons, nerves, and blood vessels that make up the foot all work together. That's why you need to condition your body, build up to a routine, and stretch your muscles, tendons, and ligaments before and after each run. Debilitating muscle strain or more serious injury can result when runners or joggers don't build up their routines and allow their bodies to strengthen over time.
Conventional wisdom has often held that 100% cotton socks are the best for your feet. It is a natural material, so it must be good for you, right? Cotton socks are actually not my favorite. I tend to prefer a blend of acrylic or other natural fibers like wool. What is wrong with cotton? Cotton fibers tend to hold and absorb more heat and moisture. Acrylic is better at wicking - or removing - heat and moisture from your skin. Cotton fibers also tend to get compressed by your foot and shoe. They don't "bounce back" as well, so the cushioning or shock absorption is not as good.
