Choose a shoe that provides stability on the inside and outside of the foot. Flexibility in the sole beneath the ball of the foot allows repeated quick forward movements. Less shock absorption is required in tennis shoes. On soft courts, wear a softer-soled shoe that allows better traction. On hard courts, select a sole with greater tread.
Basketball shoes Choose a shoe with a thick, stiff sole that gives extra stability.
A high-top shoe provides support when landing from a jump and helps prevent ankle sprains. These shoes combine several of the above features for people who don't spend enough time on any one activity to need a sport-specific shoe. A good cross-trainer should have the flexibility in the forefoot for running, combined with the lateral control for aerobics or tennis. For example, if your ankles turn easily, you might need a shoe with a wide heel. If you have trouble with shinsplints, you might need a shoe with more shock absorption.
