Abstract: Disclosed is a shoe including an upper for receiving a foot and a sole unit with a heel region and forefoot region, wherein an additional weight is arranged in at least one of the forefoot region and the heel region of the sole unit to stabilize the foot against at least one torque acting on a wearer's foot.

Abstract: The invention relates to a bladder for an inflatable ball including structure for receiving an electronic device therein. The structure facilitates at least one of cushioning, positioning, locating, and supporting the electronic device. The structure cushions reaction forces arising from a foot strike to the bladder and/or provides a restoring force to the electronic device subsequent to a foot strike to maintain the device in its predetermined position.

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.
