Some runners are supinators, which means their foot to rolls outward too much.
They land on the outside edge but instead of rolling inward, they stay on the outside. When you run, your foot is supposed to first hit the ground slightly on the outside edge of the shoe and then roll inward slightly to the ball of your foot, allowing your foot and body to absorb the shock.
