Abstract: A driving shoe that is also comfortable for walking includes extensive cushioning in the shoe's heel regions and sides and a line of substantially constant curvature in the heel region extending to the rear of the shoe that allows for rapid pivoting between the accelerator and brake without having to lift the foot during driving and for a more natural gait during walking.

Abstract: The present invention discloses a ground-contacting system including 3D deformation elements having interiors filled with either a compressible fluid, such as a gas, or filled with other materials such as liquids, foams, viscous materials and/or viscoelastic materials. The 3D elements are designed to deform, distort,l or deflect in three mutually orthogonal directions simultaneously and are associated directly with the surfaces that routinely come in direct contact with a ground surface such as the underside of the sole and side portions of the shoe upper near the sole. The 3D elements are also designed to decrease the amount of force transferred to the wearers feet, legs, back, and joints due to their ability to distort three dimensionally and to dissipate the energy of foot fall into thermal energy.
