Flat feet and high arches: Regular shoes are designed to fit normally arched feet. However, because the soles of flat feet are insufficiently arched, making it difficult to maintain a solid footing, it is best for people with flat feet to add an arch support when exercising, as this will reduce the chance of soreness.
扁平足與高弓足：一般鞋子都是依照正常的足弓高度來設計，但扁平足是因為腳底的弓起高度不足，容易重心不穩，運動時最好加上「足弓墊」，腳比較不容易痠痛。
