Abstract
A footwear sole having a variety of cushioning materials to prevent, reduce and/or eliminate foot fatigue, plantar fasciitis, and metatarsal injuries as a result of improper weight distribution to the bottom of the foot. These cushioning materials can possess differing densities and can be arranged in such a fashion so as to force the impact of the body's weight on the foot to dissipate outwards rather than straight down. The sole includes a multi-layered metatarsal design and a multi-layered heel design. When the force of the body's weight is directed downwards, it results in the wearer's heel and metatarsal absorbing the body's weight, The present invention helps to prevent or reduce this by dissipating the force outwards from the foot. An expandable ball can also be included within the heel design for further absorbing impact at heel strike.
