Your gait and stride can impact the sneaker’s lifespan. If you overpronate, that is your ankles and foot roll inward, it can cause premature wear towards the inside of the shoe. Severe overpronation can even cause extra wear and tear on the materials in the upper because the foot’s arch extends onto materials not designed to support the arch. Supination is when the foot rolls outward with each step. This, too, can cause uneven wear of the tread and potentially the shoe’s upper.
