  • Patent number: 5361518
    Abstract: A sport shoe with an outsole cleat-type gripping element is constructed so that, even in an inclined position of the outsole, the supporting areas of the gripping element or elements have as complete a ground contact as possible, without the gripping element being damaged or destroyed by excessive lateral forces. Further, the damping property of the gripping element can be matched in a simple way to the respective requirements. In particular, in accordance with a preferred embodiment of the invention these characteristics are obtained by providing a receiving device, which has an inside thread for receiving the threaded bolt for at least one gripping element, in a holding insert that is embedded in the outsole, the receiving device being mounted so as to be both axially movable and slightly tiltable laterally without being able to rotate.

  • Patent number: 5197206
    Abstract: A shoe, especially a sport or rehabilitation shoe with a shoe sole with at least one insert part formed of a honeycomb body of elastic compressible material, and having honeycomb cells of which the central axes run at least approximately perpendicular to the plane of the sole provides the honeycomb cells, in an area under the heel bone, in a central portion of the honeycomb body with a greater surface area, when seen in top view, than honeycomb cells surrounding the central portion. Thus, the central part of the honeycomb body represents the actual damping part, while the edge area surrounding it, acts as a support for the heel edge part, having a controllable stiffness or restoring force. Furthermore, the surface area of the honeycomb cells decreases in radially outward directions from the center, and preferably, the honeycomb cells are arranged in rings about a largest central cell with the honeycomb cells of the rings being elongated in a circumferential direction about the central cell.

  • Patent number: 5197207
    Abstract: A sport shoe or rehabilitation shoe with a shoe sole with at least one insert part that is formed as a honeycomb body of elastic compressible material, the cells of which have central axes that run at least approximately perpendicular to the sole plane, has honeycomb cells in an area under a flexible zone of the forefoot which are provided with a surface area that increases, as seen in top view, from one side edge to an opposite side edge of the sole or midsole. This feature has the effect of achieving a stabilizing of the foot in running, especially in long-distance running, for example, in jogging, cross-country running, marathon running or the like, in the area of the forefoot, if the user's foot usually tends to tilt inward or outward (forefoot varus or valgus) in running. Further, the damping effect and the flexibility of such a shoe in the area of the forefoot are optimized.

  • Patent number: 5174049
    Abstract: A shoe, in particular an athletic or rehabilitative shoe having a resilient cushioning sole layer within which at least one insert part made of a honeycomb body of elastically compressive material is embedded with its central axes oriented perpendicular to the plane of the sole and honeycomb body. For improved resilient and energy return, the honeycomb body is made so that even the cells on the periphery of the body are closed in a gastight manner. Furthermore, in accordance with certain embodiments, the honeycomb insert is mounted in the shoe in a manner which permits endwise viewing of the cells of the honeycomb insert, while protecting the honeycomb against damaging ground contact during use. The honeycomb body can be embedded as an insert in a midsole or heel wedge layer.

  • Patent number: 5134790
    Abstract: A shoe, especially a sport shoe, with a shoe sole, which is composed of an outsole, a midsole of elastically springy material and an insole, and a honeycomb body with cell walls oriented approximately perpendicular to the shoe outsole, is improved so that additional damping, especially at the moment that the shoe sole engages on the ground is made possible. This is achieved in that a honeycomb is incorporated into the midsole, as a part of the midsole itself or as a sole part connected or inserted in the midsole has cell walls that are gas-permeable so as to enable gas to be exchanged between adjacent honeycomb cells.
