An article of footwear includes a midsole, an upper disposed above the midsole, and an outsole disposed below the midsole. The midsole includes a unitary lattice structure having an upper side and a lower side, wherein the upper side is a user-facing side and the lower side is a ground-facing side. The midsole further includes an upper rim integrally formed with the unitary lattice structure. The upper rim extends around an upper perimeter defined on the upper side of the lattice structure.

A sole structure for an article of footwear comprises a midsole system with a plurality of cushioning units, each having multiple cushioning layers configured to work together as a system to absorb a compressive load, such as a dynamic compressive load due to impact with the ground, in stages of progressive cushioning according to the relative stiffness values of the layers. Various midsole systems disclosed include isolated cushioning units, linked cushioning units, sole layers having stanchions interfacing with the midsole system, midsole systems with sole layers having keyed and unkeyed portions overlying a bladder, and midsole systems with vertically-stacked cushioning units disposed in inverted relationship to one another.

A sole structure for an article of footwear comprises a midsole having four stacked polymeric sheets bonded to one another to define a first cushioning layer, a second cushioning layer, and a third cushioning layer. Each cushioning layer comprises a sealed chamber retaining gas in isolation from each other sealed chamber. Bonds between adjacent ones of the sheets are arranged such that the third cushioning layer is stacked directly above the first cushioning layer with the second cushioning layer bordering both the first cushioning layer and the third cushioning layer, and the sealed chamber of the second cushioning layer includes a plurality of elongated segments each extending lengthwise across a longitudinal midline of the midsole at a respective acute angle to the longitudinal midline.

A sole structure for an article of footwear comprises a midsole including a first cushioning layer, a second cushioning layer, and a third cushioning layer. The first cushioning layer has a central portion, and a peripheral portion surrounding the central portion. The first cushioning layer, the second cushioning layer, and the third cushioning layer are stacked with the second cushioning layer directly overlying the peripheral portion of the first cushioning layer, and the third cushioning layer overlying the second cushioning layer and directly overlying the central portion of the first cushioning layer. The first cushioning layer has a domed lower surface extending away from the second cushioning layer and the third cushioning layer and substantially centered under the central portion.

A base is provided for a ski boot comprising a sole and an outsole element that is positioned in a predetermined position relative to a longitudinal axis (L). The outsole element is positioned on the sole by using two projections that are carried by one or other of the sole and the outsole element and that locate in holes or cavities defined by the other. Preferably, the projections are carried by the outsole element and locate in holes or cavities defined by the sole. The projections may be integrally formed with the outsole element or the sole. Alternatively, they may be formed by injected pins, rivets, fasteners, t-nuts, or screws.

Described is a sock, in particular a soccer sock, having at least one first portion with a synthetic fiber having a diameter of less than 1 μm, wherein the at least one first portion is arranged at least partly in a heel part of the sock, and wherein the at least one first portion comprises more than 30%, preferably more than 50% and more preferably more than 80% of the surface of the sock encompassing a foot of a wearer when worn.

A shoe includes a first plate, a second plate, a third plate, filler material, springs, an insole, and a midsole. The first plate and the second plate are hingedly connected to each other. The filler material is located between the first plate and the second plate. The springs are located within openings in the filler material. The third plate is affixed to a top surface of the first plate. The insole is located above the third plate. The first plate is made of a thermoplastic elastomer, and the third plate is made of carbon fiber. Another shoe includes a midsole, a plate located above the midsole, springs located at least partially within openings in the midsole, and a spring holding unit located below the midsole for holding the springs. The spring holding unit includes spring holding members and branches connecting corresponding spring holding members.

A three-layered article of footwear construction having an outsole, midsole, and footbed. The outsole is made out of a rubber and has a mating relationship with the midsole. The midsole is made of a single density blown ethylene-vinyl acetate copolymer (EVA). The midsole includes a first air cavity in the forefoot region and a second air cavity in the hind foot. The air cavities act like a suspension units under the impact areas of a foot giving improved impact reduction and help in reducing muscular and joint stress, fatigue, and impact during the normal walking gait motion. The footbed is made of a dual-density EVA. The dual density of the footbed allows for a greater flexibility and cushioning in the forefoot and heel regions due to its lighter density and provides greater support and stability around the perimeter area of the footbed due to its heavier density.

The disclosed embodiments relate to portions of an article of footwear formed from an extruded member. In certain embodiments, a sole or portion of a sole can be formed from one or more extruded members. In certain embodiments, the extruded member can be a single, continuous piece of solid material. In certain embodiments, a sole for an article of footwear can be fashioned from an extruded member formed in a controlled geometric pattern. In certain embodiments, the sole can include one or more layers.
