If sweaty workouts leave your tootsies blistered, then those stinky socks you just threw in the hamper could be to blame.
Some sock materials are better than others at preventing blister-causing friction.
Cotton socks chafed the most at high moisture (meaning they're most likely to cause blisters), while nylon and acrylic-fiber socks had lower friction levels.
Non-cotton socks wick away moisture, so they're less likely to cause blisters. Look for socks with little or no cotton, try it out and let us know what you think.
