Footwear, particularly athletic shoes, that has a sole structure (28) copying the underlying support, stability and cushioning structures of the human foot. Still more particularly, this invention relates to the use of relatively flexible and inelastic fiber (155a, 182) within the material of the shoe sole to provide both flexibility and firmness under load-bearing pressure. It also relates to the use of sipes, particularly those that roughly parallel the foot sole of the wearer in frontal plane cross sections (152, 181), contained within the shoe sole under the load-bearing structures of the wearer's foot to provide the firmness and flexibility to deform to flatten under weight-bearing loads in parallel with the wearer's foot sole. Finally, it relates to providing additional shoe sole width (figures 19-22) to support those areas identified as mandatory to maintaining the naturally firm lateral support of the wearer's foot sole during extreme sideways motion while load-bearing. |
