A shoe sole includes a resilient member, and has a bottom surface as a ground contact surface and a top surface. The resilient member has a three-dimensional shape formed by a wall having an outer shape defined by a pair of parallel flat or curved surfaces, and may buckle when the resilient member receives a compressive stress applied in a normal direction to the bottom surface. In the shoe sole, when a load is applied to the shoe sole in a gradually increasing manner such that a compressive stress is applied to the resilient member in the normal direction, the resilient member starts to buckle when a stress applied to the resilient member is within a range of 0.05 MPa or more and 0.55 MPa or less and a strain of the resilient member in the normal direction is within a range of 10% or more and 60% or less.

A sole structure for an article of footwear may have a midsole system that includes a sole plate having a forefoot region and a midfoot region. The sole plate may have a foot-facing surface and a ground-facing surface opposite to the foot-facing surface. The sole plate may define a through hole extending from the foot-facing surface to the ground-facing surface in the forefoot region. The through hole may be closer to a medial edge of the sole plate than to a lateral edge of the sole plate. The sole plate may have ridges extending longitudinally in the midfoot region and in the forefoot region. The ridges may have crests at least some of which may extend non-parallel with one another in a longitudinal direction of the sole plate.

A cushioning member for an article of footwear is provided and includes a first barrier member defining a first compartment and a second compartment and being formed from a first material. A second barrier member is attached to the first barrier member, covers the first compartment to define a first interior void, and covers the second compartment to define a second interior void. The second barrier is formed from a second material different than the first material. The cushioning member also includes a first quantity of particulate matter disposed within the first interior void and a second quantity of particulate matter disposed within the second interior void.

The present invention regards a sole for a sport shoe, work shoe or leisure shoe including a main body having a lower layer delimiting a surface, lower during use, set to come into contact with the ground and an upper layer set to come into contact with a foot of a user or to support from the bottom, during use, an insole.

A sole structure for an article of footwear includes a unitary cushioning component comprising a plurality of scrap foam pieces configured as a plurality of different polyhedron shapes and a resin binder securing the scrap foam pieces to one another. The sole structure may comprise a midsole including an outer shell defining a central cavity. The cushioning component may be disposed in the central cavity as a core of the midsole. A method of manufacturing an article of footwear cutting the scrap foam body into pieces, mixing the pieces with a resin binder, and compression molding the mixed pieces and resin binder in a mold to form a cushioning component of a sole structure of the article of footwear.

A bladder for an article of footwear extends from an anterior end to a posterior end and includes a first chamber disposed in an interior region of the bladder and a second chamber at least partially surrounding the first chamber. The first chamber includes a first interior void having a first pressure and the second chamber includes a second interior void having a second pressure. In some implementations, the second chamber includes a plurality of lobes arranged in series and each having a first end, a second end, and an intermediate portion disposed between the first end and the second end. Each lobe has a greater thickness at the intermediate portion than at the first end and the second end, such that each lobe tapers from the intermediate portion to the first end and the second end.

A sole structure for an article of footwear includes an outsole defining a ground-contacting surface, a midsole disposed between the outsole and the upper, and a plate attached to the midsole and defining a recess extending in a direction away from the outsole and toward the upper, the recess including a first retainer. The sole structure further includes a first cushion having a first portion received within the recess, the first portion engaging the first retainer to maintain a desired position of the first cushion relative to the plate.

A fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.
