A high performance dorsiflexion shoe (10) has a sole and a constraining device (16) above the metatarsal-phalangeal joint. The sole has a ground-contacting surface (26), a forefoot region (30), a midfoot region (32) and a heel portion (34). The forefoot region (30) is made of a high density material, and has a thickness (T), measured in a direction perpendicular to the ground-contacting surface (26) of the sole, greater than the thickness (t) of the heel portion, thereby defining a characteristic angle (a) of declination from the forefoot region (30) to the heel portion (34). The constraining device (16) substantially constrains a wearer's metatarsal-phalangeal joints (20) from movement when exercising. The forefoot region has a curved form (28) defined so as to further minimize flexion of the metatarsal~phalangeal joint (20).

Chaussure haute performance pourvue d'une semelle et d'un dispositif de contrainte positionné au-dessus de l'articulation métatarsophalangienne. La semelle est pourvue d'une surface en contact avec le sol, une partie avant-pied, une partie intermédiaire et une partie talon. La partie avant-pied est faite d'un matériau haute densité, et est d'une épaisseur supérieure à l'épaisseur de la partie talon lorsqu'on la mesure perpendiculairement par rapport à la surface en contact avec le sol de la semelle. Ce qui permet de délimiter un angle de déclinaison caractéristique depuis la partie avant-pied jusqu'à la partie talon. Le dispositif de contrainte empêche pratiquement tout mouvement des articulations métatarsophalangiennes du porteur en cours de déplacement. La partie avant-pied a une forme incurvée de manière à réduire encore la flexion de l'articulation métatarsophalangienne.
