A directionally flexible shank for an article of footwear is disclosed, which provides support to the bottom of a user's foot while providing flexibility for foot movements in one or more particular directions. The directionally flexible shank may also support the arch of the foot. The directionally flexible shank may include a plurality of articulatable segments that can easily rotate with respect to each other in a first direction and thereby permit the directionally flexible shank to flex away from the foot, while limiting articulation in an opposite direction. The articulatable segments are connected to each other via hinge structures, which may include living hinges formed of a thermoplastic material. The hinge structures may also be formed from a flexible sheet attached to a bottom portion of the directionally flexible shank. Methods are also disclosed for manufacturing the directionally flexible shank.

Articles of apparel include: (a) a garment structure having one or more fabric elements structured and arranged to provide a close fit to at least one predetermined portion of a body (e.g., area(s) of the body for which enhanced position sensing and/or feedback are desired, such as the lower back, the arch of the foot, etc.); and (b) a body position feedback system engaged with or integrally formed as part of the garment structure. The body position feedback system may apply higher tensile or constricting (compressive) forces to selected portions of the wearer's body, which can help stimulate or interact with nerves and deep tissue receptors located in various portions of the body. The increased forces at selected locations of the body give the wearer sensory feedback regarding the position or orientation of these parts of the body and can improve or accelerate development of “muscle memory.”

A new design, applicable to most shoe types, having isolated, compressible rubber cushions as the only contact points with the ground. These cushions, usually 4 in number, are attached at only key points to an overlying flexible skeleton, made of a durable but bendable support structure. The ‘skeleton’ in turn is affixed to an overlying compressible ‘mattress’. This entire structure, consisting of compressible mattress, skeleton, and cushions duplicates the arch of the foot. Under the force of walking, running, etc. the rubber cushions will compress to absorb the force of the step. The overlying skeleton will also absorb energy by bowing convex downward at the toes, middle, and heel of the foot. Similarly the air space of the overlying mattress will also be compressed, absorbing pressure. Upon lifting the foot, the opposite actions will occur, releasing energy in an upward and forward direction, and thereby both lifting and propelling the foot.

The present invention relates to the upper U of an athletic shoe comprising a first opening 1 out of which the foot sticks upwards during wearing and a second opening 2 which is closed with a tongue.

Each of the stretchable parts 50, 51 is provided so as to essentially cross one of side faces of the upper U from a top surface of a sole S to the second opening 2. Young's modulus along the lengthwise direction L of the foot of each of the stretchable parts 50, 51 is set smaller than that of the front part 3 and the rear part 4.

A cover for a lace-up football boot has a continuous, elastically expandable sleeve (1). The sleeve is, in use, stretched around the boot so that the latter extends through the sleeve with the toe of the boot protruding from the end of the sleeve, and that the underside of the sleeve engages the portion of the underside of the boot in a region between the heal and the toe (i.e. under the arch of the foot). This engagement between the sleeve and the boot is sufficient to hold the sleeve in position on the boot in use, the sleeve also covering the bootlaces to prevent the latter from untying. At least part of the cover may also be transparent so as to reveal ornamental features or indicia on the boot.
