Abstract

La présente invention concerne un procédé de fabrication d’une semelle à côtés gauches et droits en forme d’arc, la semelle ayant une surface inférieure en forme d’arc vers le bas, d’une extrémité de gauche vers une extrémité de droite, afin d’avoir des côtés gauches et droits en forme d’arc, et une semelle intercalaire antichoc fixée sur une semelle d’usure de ladite semelle étant composée d’un matériau plus souple que les matériaux de la semelle d’usure, et d’une semelle intercalaire supérieure. Ainsi, la partie de la surface inférieure extérieure de la semelle qui se pose sur le sol pendant la marche glisse de façon à être aplatie sur le sol, afin de donner à l’utilisateur l’impression de marcher pieds nus sur le sable.
