A HEEL DESIGN FOR FOOTWEAR DESIGNED SUCH THAT THE NATURAL LEVER ARM OF THE HEEL OF THE FOOT IS RELATIVELY UNCHANGED ENSURING NO INCREASE IN FORCES OF THE HEEL STRIKE PHASE OF BIPEDAL LOCOMOTION. THE EFFECT BEING NO HEEL OF FOOTWEAR INDUCED SHIN SPLINTS, PLANTAR FASCIITIS OR RELATED PATHOLOGIES

摘要

A design of heel of footwear which reproduces the contacting portion, or minimally the key elements of the heel of the wearer in shape and placement in relation to the foot and function. That is a shape of heel in the footwear which does not imbalance the natural functions of the foot in bipedal locomotion through addition of material outside the confines of the design, shape and measurements of the wearer's own heel in the sagittal plane. This design of heel will afford the wearer the grace, smoothness and ease of stride enjoyed while barefoot. The wearer of a shoe with such a shape of heel will not suffer from shocks and strains to the foot and supporting members caused by the shape of the heel of the shoe. These being the types of shocks and strains contributing largely to shin splints and plantar fasciitis and attendant pathologies.
