Abstract
A shoe which includes a metatarsal arch support comprising a heel portion; a medial portion extending from the heel portion; and a metatarsal portion extending from the medial portion and terminating in a round metatarsal edge; which support increases in width from the medial portion to the metatarsal edge; the medial portion having a curved transverse cross-sectional shape; and the metatarsal portion having a crescent transverse cross-sectional shape which flattens by way of a wedge-shape into the round metatarsal edge; the metatarsal edge being adapted to be substantially below the joints of the five metatarsal bones to the proximal phalanges.
