Abstract

An improvement in the design of a shoe wherein a flexible material is placed inside the shoe sole at the level over the insole and below the toes of the foot and either above or also in line with the midsole, so that the wearer'"'"'s toes rest along the flexible material when the wearer'"'"'s foot is inserted into the shoe. The flexible material also extends to the area at the base of the big toe and behind the ball of the foot behind the big toe under the 1^st metatarso-phalange joint base of the big toe. In a variation of the present invention, the flexible material only extends under the toes and does not extend behind the big toe. Therefore, in addition to all five toes resting on the flexible material, the ball of the foot area at the base of the big toe also rests on the flexible material. By filling the frontal section of the shoe sole with the flexible material, the flexible material permits the toes to curl downward when walking. The flexible material can be any type of-gel, deformable liquid or gel containing pack, polyurethane gel, silicone, soft rubber, foam, memory soft material, neoprene, polyvinyl, polyethylene, polyurethane and any type of natural or synthetic soft flexible material to simulate walking on sand.
