Overpronation and supination describe the motion of the foot during walking or running. To determine if you’re an overpronator or supinator, examine your current running shoes.
Overpronators wear down the outer sole of shoes along the inside near the ball of the foot and tend to have flat feet. Supinators wear down shoe soles along the outer edge, and their feet tend to have high arches.
Overpronation can lead to injuries or other issues. Overpronation occurs when feet roll inward too much and cause the rest of the body to compensate. Runners who overpronate usually have a flat or weak arch that allows this motion to occur.
To combat the issue of overpronation, Nike offers motion control footwear that provides excellent cushioning and stability. Nike shoes in the Stability category, such as the Nike LunarGlide, can help with overpronation.
Supination, or underpronation, is the opposite of pronation but also a normal motion. A foot is in supination when the ankle appears to be tipped outside and the runner is standing on the outside border of the foot.
Nike shoes from the Neutral Running category can be helpful for supinators. The Nike Air Max, Nike Air Zoom Vomero, and Nike Air Pegasus are some suggested Neutral Running shoes.
