Match your foot type
A mismatch that puts your feet through an unnatural pattern can cause all kinds of problems and injuries. Feet generally fall into these three categories:
1. If your feet are rigid, curved and tend to underpronate — or roll outward excessively on landing (often the case with high arches)— you need a shoe with a curved last (the shape of the outsole), soft cushioning and strong midfoot support.
2. If your feet are neutral, they need shoes with a semi-curved last and moderate cushioning.
3. If your feet are straight or flexible and typically overpronate —or roll excessively inward on landing (often the case with low arches)— they need a straight last and a firm insert on the arch side of the midsole, a firm midsole and a lower heel.
