The invention relates to footwear comprising a multi-layer structure of the sole, with said sole being composed of at least one outsole (3), an optional insole as well as a midsole (2), wherein the midsole (2) is made of an elastic material having an open-cell structure provided with a gas- and liquid-tight outer skin, with said cell structure being filled with at least one fluidic medium.

An article of footwear includes an inner contact material operable to provide an interface between the article of footwear and portions of a wearer's foot. The inner contact material defines an inner foot opening through which a foot can be received. The inner contact material extends downwardly about the foot from the inner foot opening. An outer support material at least partially circumscribes portions of the inner contact material. The outer support material defines an outer foot opening through which a foot can be received. The outer support material extends downwardly about the foot from the outer foot opening. The inner foot opening is positioned higher around a periphery of the foot than is the outer foot opening so as to expose portions of the inner contact material above the outer support material.

Provided is a slipper including an outsole 100 in contact with a floor, a midsole 200 assembled on an upper side of the outsole 100 and supporting a foot of a user, and a balance foam 300 disposed between the outsole 100 and the midsole 200 and made of a memory foam material. The slipper is to be modified to fit a shape of the sole of the foot of the user by placing a balance form between the outsole and the midsole, thereby improving the wearing comfort of the user.

A footwear includes: a foot bed portion that supports a sole of a foot of a wearer and has a ground contact surface; and a foot cover portion that covers an instep of the foot of the wearer. At least a part of the foot bed portion and at least a part of the foot cover portion are formed of a single additively manufactured product produced by a stereolithography-type three-dimensional additively manufacturing method, and a protruding portion is provided on an outer surface defined by the additively manufactured product of the foot cover portion.

A protective footwear is provided that selectively attaches to a cleat to at least partially cover the protrusions on the bottom of the cleat and allow an athlete or other person to safely traverse a hard surface like concrete. The protective footwear has a strap system that provides the selective attachment to the cleat, and a pliable inner sole of the protective footwear conforms to the protrusions on the cleat. As a result, the protrusions are protected and do not contact a hard surface like concrete. The athlete or other person is less likely to slip and fall by using the protective footwear among other benefits described herein.
