Title
(EN) SPORT SHOE SOLE PROVIDED WITH OBSTACLES
(FR) SEMELLE DE CHAUSSURE DE SPORT DOTEE DE NERVURES
Abstract
(EN)
Sport shoe sole provided with either stationary or replaceable obstacles, and more specifically to the sole of a sport shoe designed for running or jogging. The obstacles are located in the sole construction in the region between the point of support (C) of the ball of the foot and the centre of gravity (P') of the heel. The moment arm (x2) of the foot is shorter than the respective moment arm (x1) with an ordinary sport shoe. This saves energy, and the dynamic resistance of the calf and the Achilles tendon with each step is reduced in comparison to the prior art, so that the running proceeds economically and effectively. The heel platform located behind the centre of gravity (P') of the heel is lowered down, in which case the moment arm (x3) of the heel is eliminated, and the front muscle of the lower leg is released from unnecessary strain.
(FR)
Semelle de chaussure de sport dotée soit de nervures fixes, soit de nervures remplaçables, plus spécifiquement semelle de chaussure de sport conçue pour la course à pieds ou le jogging. Les nervures sont situées dans la semelle dans la zone séparant le point de support C de la cambrure du pied et le centre de gravité (P') du talon. Le bras du couple (x2) du pied est inférieur au bras de couple respectif (x1) avec une chaussure de sport ordinaire. On économise ainsi de l'énergie et la résistance dynamique du molet et du tendon d'Achille est réduite à chaque pas par rapport à l'art antérieur, si bien que la course est plus économique et plus efficace. La plate-forme de talon située derrière le centre de gravité (P') du talon est abaissée; dans ce cas le bras du couple (x3) du talon est éliminé et le muscle frontal de la jambe inférieure est soulagé d'un effort inutile.
