An athletic shoe extending between toe (1) and heel (3) and comprising upper (5) attached to outsole (7) via comfort sole (9). According to the invention, the athletic shoe comprises shell (13) make of plastic or composite material, inserted between upper (5) and comfort sole (9) and to which it is attached at heel (1).

A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer; and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.

The present invention provides for a sole structure for a shoe having a bottom surface, comprising, inter alia, a forefoot sole portion, arranged towards a distal end along a longitudinal central axis of said sole structure; a rearfoot sole portion, arranged towards a proximal end along said longitudinal central axis of said sole structure; and an articulation portion, adapted to operably couple said forefoot sole portion and said rearfoot sole portion, so as to allow relative movement between said forefoot sole portion and said rearfoot sole portion matching the triplanar movement provided by the midtarsal joint in any one of the frontal, sagittal and transverse plane of the foot, during use.

Golf shoes, and specifically, to golf shoes enabling increased driving distance and precise directivity, whereby, in order to enable weight distribution, seating grooves, in which a forefoot portion (ball) and a rearfoot portion (heel) are respectively seated, are respectively formed on the front and rear of the upper surface of an insole, and anti-slip protrusions are respectively formed on one side surface of the front of the upper surface of the insole, and the other side surface of the rear of the upper surface of the insole, so as to prevent the foot from slipping and thus rotating, and thus weight distribution is easily achieved at taking stance and addressing a ball, even by only being grounded on the ground, and the foot is prevented from slipping in the golf shoes at finish.

A sole structure for an article of footwear includes a bladder assembly having a first fluid-filled chamber spaced apart from a second fluid-filled chamber and a chassis. The chassis includes a plate. The plate has a bottom surface configured to accommodate the first fluid-filled chamber and the second fluid-filled chamber. The chassis further includes a shank configured to be seated to a mid-foot portion of the bottom surface of the plate and separate the first fluid-filled chamber from the second fluid filled chamber.

A plate is used for a sole that forms a part of a shoe. The plate includes a mid- and rear-foot support portion in a shape extending from a position superimposed on a rear end portion of a metatarsal bone of a wearer of the shoe in a thickness direction of the sole to a position superimposed on a heel bone of the wearer, the mid- and rear-foot support portion supporting a midfoot portion and a rear foot portion of the wearer. The mid- and rear-foot support portion is in a shape convex upward in a cross-section in a foot width direction.

A sole for sports shoes is provided including a base or tread component, a top or midsole component and at least one intermediate or elastic cushioning component. Advantageously, the sole is able to provide high cushioning, elastic yield and stability thanks to the mechanical or structural characteristics of the sole.

A device for use in a shoe includes a first foot, a second foot, a third foot, a fourth foot, a first flexible leg, a second flexible leg, a third flexible leg, and a fourth flexible leg. The first flexible leg extends from the first foot and is curved. The second flexible leg extends from the second foot and is curved. The third flexible leg extends from the third foot and is curved. The fourth flexible leg extends from the fourth foot and is curved. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are joined together with each other at a common area. The first flexible leg, second flexible leg, third flexible leg, and fourth flexible leg are configured to store energy when a force is applied to the common area, and to return energy when the force is removed from the common area.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability. These products include human and other footwear, both soles and uppers, as well as orthotics; athletic, occupational and medical equipment and apparel; padding or cushioning, such as for equipment or tool handles, as well as furniture; balls; tires; and any other structural or support elements in a mechanical, architectural, or any other product.

An article of footwear includes a sole structure and an upper that is attached to the sole structure. The upper defines a cavity that is configured to receive a foot of a wearer. The upper is at least partially defined by a textile. The textile includes a first area that is substantially smooth. The first area defines a reference boundary that conforms to the cavity. The textile includes a second area. The second area includes a plurality of projection structures that project away from the reference boundary and outwardly from the cavity at varying heights. The second area includes a plurality of recess structures that recess away from the reference boundary and inwardly toward the cavity. The plurality of projection structures and the plurality of recess structures are in an alternating arrangement across the textile.
