Pros and cons of being born with high arched feet?

Stability/Rigidity. High arches are generally less flexible, which translates into greater stability. (the reverse is also true for flatfeet.) this can translate into better athletic ability with greater push-off strength for running and jumping. On the downside, shock absorption is poor due to the rigidity, so stress fractures are more common. Ankle sprains are also much more common with high arches.
