title: [Biomechanical and orthopedic problems of tennis and indoor sports shoe].
abstract: In contrast to running, a large number of indoor sports show a variety of body and foot movements with fast changes of direction. These "stop-and-go" movements (including jumps and rotations) produce loads at the joints of the foot, knee and hip in an order of magnitude often underestimated. The goal of this investigation was to provide an overview over various indoor sports movements and to draw conclusions with respect to sport shoe constructions. Reconsideration of the functionality of the foot led to shoe constructions which allow the shoe to rotate about its longitudinal axis (torsion), a movement with which the forefoot can again "reach" for the ground in landing situations. However, the problem of the rear foot stability and cushioning at a rear foot touch down is not yet solved. Therefore it must be postulated that shoes for indoor sports and tennis should be provided with an increased lateral stability at the rear foot.
