  • Patent number: 11950654
    Abstract: A fluid-filled chamber may have a barrier, a stacked tensile member, and a fluid. The barrier may be formed from a polymer material that is sealed to define an interior void. The stacked tensile member may be located within the interior void and includes a first tensile element and a second tensile element that are joined to each other. Additionally, opposite sides of the stacked tensile member are joined to the barrier. The fluid is located within the interior void and may be pressurized to place an outward force upon the barrier and induce tension in the stacked tensile member. In some configurations, each of the tensile elements may be a spacer textile.

    Abstract: A footwear sole obtained by molding a single polymeric material, the footwear sole includes a lower surface to contact the ground, and an upper surface to support an insole and, on the upper surface, at least one elastically deformable cushioning element. The cushioning element includes an elongated element cantileverly protruding from the upper surface, and a plurality of tabs extending from the upper surface that are arranged around the elongated element, thereby defining a dome. In an undeformed configuration of the cushioning element the tabs are upright, and there is a gap between the tabs and the elongated element, and in a deformed configuration of the cushioning element the tabs are each bent towards the elongated element and in abutment against it. The switching from the undeformed to the deformed causes the area of the bearing surface provided to the insole by each cushioning element to gradually increase.

  • Patent number: 11864631
    Abstract: A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.

  • Patent number: 11297895
    Abstract: A sole assembly for an article of footwear comprises a sole plate with a foot-facing surface with a recess disposed in the foot-facing surface. An insert plate is disposed in the recess. A length of the insert plate between anterior and posterior ends of the insert plate is less than a length of the recess. The insert plate flexes free of compressive loading by the sole plate when a forefoot portion of the sole assembly is dorsiflexed in a first portion of a flexion range, and operatively engages with the sole plate when the forefoot portion is dorsiflexed in a second portion of the flexion range that includes flex angles greater than in the first portion of the flexion range. The sole assembly is dorsiflexed, for example, when the forefoot portion is flexed in accordance with toes bending toward the top of the foot.
