Abstract: Soles for footwear and footwear are disclosed. The sole may include a midsole having a first surface. The sole may additionally include an outsole having a second surface and a plurality of first recesses. The second surface may be attached to the first surface. The first surface and the plurality of first recesses may define a plurality of chambers. One or more chambers of the plurality of chambers may include trapped air. The midsole may further include first protruding portions that extend downwardly from the first surface toward one or more first recesses of the plurality of first recesses.

Abstract: Methods of and molds for manufacturing footwear are disclosed. In one example, the method may include forming at least one molded portion adjacent to at least one non-molded portion such that part of the at least one molded portion overlaps and contacts the at least one non-molded portion, and forming the at least one molded portion to include end portions that are adjacent the part of the at least one molded portion and that extend away from the at least one non-molded portion such that the end portions do not contact the at least one non-molded portion; moving the end portions of the at least one molded portion toward the at least one non-molded portion such that the end portions contact the at least one non-molded portion; and securing the end portions of the at least one molded portion to the at least one non-molded portion.

Abstract: Footwear and soles for footwear are disclosed. The sole may include an energy transfer base. The energy transfer base may include top and bottom surfaces, and opposed first and second side surfaces. The energy transfer base may include at least one cavity. The at least one cavity may define upper and lower portions of the energy transfer base. The upper portion may be configured to move away from a nominal position and toward the lower portion when a force applied to the upper portion toward the lower portion has a magnitude that is above a predetermined value, and to move back to the nominal position when at least one of (1) the force is no longer applied or (2) the magnitude of the applied force is at or below the predetermined value.

Abstract: An article of footwear may include a midsole having a flex-frame defining a plurality of cells. Some or all of the cells may be substantially filled with a foam material. The flex-frame may be made of a solid material having a greater stiffness than the foam material. The flex-frame may be unitary in construction.
