Preventing blisters on long runs

For runs over fifteen miles, friction is the enemy. Apply a thin layer of silicone-based anti-chafe stick directly to your toes and the back of your heels before putting on your socks. Pair this with double-layered socks made of merino wool or synthetic fibers; the two layers rub against each other rather than your skin, absorbing the shear forces that cause deep, painful fluid pockets.
