Athletes of several sports wear cleated or studded footwear (e.g. football, lacrosse, and baseball players). Traditionally, boots have a small number of quite long cleats (studs) to provide good traction, but these tend to increase the risk of injury from twisting motions. Anterior cruciate ligament sprains of the knee often result from the foot being fixed in place by cleats stuck in the ground as the upper body is rotated. Wearing footwear with a larger number of shorter cleats can reduce the rates of injury to the lower extremities by more than 40%.
