Abstract: A footwear system has a sole unit with a number of cavities formed between a midsole and an outsole. The cavities are complementary to one another to form groundward oriented air bulges in the outsole that are connected by a passage formed in the midsole. The passage permits movement of air between the cavities during use of the footwear system in a shoe.

Abstract: An improved exercise device including a sole with an upper surface on which a wearer's foot rests and a lower partially ground contacting surface. The sole has a heel, a midfoot, a forefoot and a toe region such that when the heel region lower surface and the forefoot region lower surface are in ground contact, the upper surface does not incline upwards from the forefoot to the heel region. The forefoot lower surface of the sole is generally radiused in a cylindrical curve about the line connecting the mid points of the first and second metatarsal-phalangeal joints of the wearer. When the wearer contracts their calf muscles, the heel section is lifted away from the ground, requiring work against gravity.

Abstract: An ostomy coupling is described of the type comprising a locking member in the form of a resilient split ring, for fastening two ostomy coupling members together. One feature of the invention is that one of the coupling members comprises a tapered seal seat surface for cooperating with a deflectable seal wing carried by the other member. The tapered seal seat has a smoothly curved taper, to enable a relatively large seal area to be provided within a low coupling profile height. Another feature of one form of the invention is that the split ring has an inclined outer surface to form a smooth profile with the coupling member on which it is carried. Another feature of another form of the invention is that each limb of the split ring is bifurcated to receive a radially projecting guide of the coupling member, on which the split ring is mounted.

Abstract: A cleated sole for footwear such as an athletic shoe designed for field sports, trail running or rugged walking. A midsole layer includes shock attenuating structures. The outsole includes a plurality of crossbeams formed as curved ground facing portions oriented from the medial to the lateral border of the sole. Cleats are mounted on the lower facing surface of the crossbeams. The outsole to midsole interface above each crossbeam is commensurate in shape to the lower facing curved surface of the crossbeam. Pressure created by a cleat striking the ground surface during use is diffused through the crossbeam, outsole and midsole into the wearer's foot. This moderates the cleat pressure pattern while providing side to side stiffness for the sole.

Abstract: An article of footwear, for example, an athletic shoe designed for walking, running, or other sports activities. The article of footwear is provided with an upper, an outsole, and a midsole positioned between the outsole and the upper. The midsole has an upper surface upon which a sole of a foot is positioned during use of the article. The midsole is provided with an external cushioning spring. This spring includes one or more angled strips of resilient elastic material. One end of a strip is fixed on the surface of the midsole or outsole at a location at least 3 mm below the upper surface of the midsole. The other end of the strip is fixed on the surface of the midsole or upper at least 3 mm vertically above the location at which the other end is fixed.
