Abstract An improved sole for a shoe made from a single piece, purposely sized to receive thereon the entire foot of the user, and of the type whose inner shank is anatomically raised at the ball portion to act as a support for the arch of the foot, includes a heel supporting zone in a lower plane than the ball supporting zone which, on the other hand, is slightly raised at its center in a rounded fashion. The sole includes means to prevent the foot from twisting outwards, when resting, and means whereby the weight of the user rests on the big toe, at the end of each stride, which means are respectively comprised of a longitudinal recess in the upper surface of the shank situated between the raised support of the arch and the outer opposite edge, and of a decrease in the thickness of the fore portion of the sole which starts approximately midway of the ball and progresses towards the toe portion, forming a curved surface, whose front view defines an oblique front, when such decrease reaches its maximum value coinciding with the supporting zone for the big toe.
An improved shoe sole made from a single piece of a size to receive thereon the entire foot of the user, said sole having: the inner shank thereof anatomically raised at the ball portion to provide a support for the arch of the foot; a ball supporting zone slightly raised at its center in a rounded fashion; a heel supporting zone in a lower plane than said ball supporting zone; means for preventing a foot from twisting outwardly when resting, said twist preventing means comprising a longitudinal recess in the upper surface of the shank at a position between the raised support for the arch and the outer opposite edge; and means for causing the weight of the user to rest on the big toe thereof at the end of each stride, said means for causing comprising a fore portion of the sole having a decrease in thickness beginning approximately midway of the ball supporting portion and progressing toward the toe portion, said decrease forming a curved surface, the front view of which defines an oblique front, said decrease being at a maximum at the supporting zone for the big toe.
