Abstract: A bladder for an inflatable ball, in particular a soccer ball, has electrical wiring wherein the wiring is at least partially arranged along a bladder wall to interconnect two electrical or electronic devices.

Abstract: The present invention relates a protective element for an athlete. The protective element can include a first flexible support layer, wherein a plurality of substantially hard projections is arranged on the first support layer, and a second flexible support layer, wherein a plurality of substantially hard receiving elements is arranged on the second support layer. The receiving elements and the projections are configured to provide flexible protection to various areas of a user's body.

Abstract: Disclosed are articles of footwear and soles therefor, in particular sports shoe soles that include openings for ventilation and vapor exchange. The soles include an insole layer with a plurality of first openings, a support layer with a plurality of second openings that partially overlap the plurality of first openings, and an outsole layer with at least one third opening that at least partially overlaps the plurality of second openings to provide fluidic communications through the sole from an interior of the shoe to an exterior of the shoe. A substantial portion of the plurality of first openings in the insole are interconnected to provide a path for diffusion. The shoes and soles can include a cushioning layer, a tread layer, a breathable membrane, and additional support elements. In addition, the shoes can be used with climate control socks to further enhance the climate control properties of the shoes.

Abstract: The invention is directed to intelligent systems for articles of footwear that adjust automatically in response to a measured performance characteristic. The intelligent systems include one or more adjustable elements coupled to a mechanism that actuates the adjustable elements in response to a signal from a sensor to modify the performance characteristic of the article of footwear. The intelligent system adjusts the performance characteristics of the article of footwear without human intervention.

Abstract: A garment for a part of the body, and in particular a sport pant, includes an elasticity element, or a number of such elements, disposed on a portion of the garment, while another portion of the garment is free of elasticity elements. As a result, the garment can store energy by elastic elongation under a movement of, for example, a leg. This energy can then be released under a second movement of the leg in the opposite direction, resulting in the garment supporting the second movement of the leg.

Abstract: The invention relates to a sliding element for a shoe sole. The sliding element includes an upper sliding surface and a lower sliding surface, wherein the lower sliding surface is arranged below the upper sliding surface so as to be slideable in at least two directions. The upper sliding surface can form a lower side of an upper heel cup and the lower sliding surface can form an upper side of a lower heel cup, wherein the upper heel cup and the lower heel cup have corresponding substantially spherical shapes. Complex multi-dimensional sliding and cushioning movements between the upper sliding surface and the lower sliding surface are made possible by the corresponding three-dimensional shapes of the two substantially spherical surfaces.

Abstract: The present invention relates to a shoe sole including a cushioning element. The shoe sole can include a heel cup or heel rim having a shape that substantially corresponds to the shape of heel of a foot. Further, the heel part can include a plurality of side walls arranged below the heel cup or rim and at least one tension element that interconnects at least one side wall to another side wall or to the heel cup or rim. The heel cup or rim, the plurality of side walls, and the at least one tension element can be integrally formed as a single piece.

Abstract: The invention relates to a shoe with a sole unit, where the sole unit includes a recess for removably receiving a housing of an electronic assembly, for example, an electronic pedometer, an accelerometer, or a speed sensor. Further, the invention relates to a housing for receiving an electronic assembly, for example, a pedometer, an accelerometer, or a speed sensor, where the housing has an outer shape corresponding to the shape of a recess formed in a shoe sole.
