CA 2488274

An outsole (1, 3), in particular, for athletic shoes (2) can be realized with a significant elastic deformability in the tangential direction so as to also achieve a superior shock-absorption when the foot contacts the ground obliquely and with a slight propulsive force. According to the invention, the sole (1) essentially is only rigid to a tangential deformation beyond at least one critical point of deformation in the region that is deformed to this critical point. This results in a correspondingly increased stability for the runner in the respective point of contact or load application. The runner is also able to push off from the point of load application without any loss in distance. A floating effect on the sole is prevented. The sole can be affixed, as a whole or in a plurality of parts, also detachably to an intermediate sole (4) of the shoe (2).

La semelle d'usure (1, 3) destinée notamment à une chaussure de sport (2) peut être réalisée avec une grande aptitude à la déformation élastique dans la direction tangentielle, ce qui offre un grand amortissement même pour une démarche oblique et légèrement de travers. Selon l'invention, la semelle (1) est, toutefois au-delà au moins d'une déformation critique dans la zone jusque là déformée, sensiblement rigide à la déformation tangentielle. Ainsi, le coureur à pied a un maintien sûr respectivement au niveau du point de marche et de charge. Cela permet au coureur de donner à nouveau une poussée à partir du point de charge même sans perte de terrain. On évite ainsi un effet de flottaison sur la semelle. La semelle peut être fixée complètement ou par sections même de façon amovible à une semelle intermédiaire (4) de la chaussure (2).
