Benefits of technology

[0005] It is a primary object of the present invention is to provide a shoe, especially an athletic shoe and especially preferably a running shoe, such that it becomes possible to adjust the spring properties and / or the damping properties of the shoe sole in a manner as defined as possible and to adapt them to given boundary conditions as well as to change these properties if necessary.

Problems solved by technology

While the resiliency of the shoe sole can be influenced via a spring insert of this type, it is not possible to adjust the spring / damping properties with such an arrangement.

Embodiment Construction

[0035]FIG. 1 shows a shoe 1 of the type which is used as a running shoe and which, as is conventional, has an upper 3. Underneath (for orientation, the direction of the upward vertical arrow V is shown) upper 3 is a midsole designated 2 as whole. Affixed to the underside of the midsole 2 is the outer sole 14, which is in the form of a rubber sole.

[0036] The midsole 2 is foamless, i.e., it does not have any foamed material, especially any foamed plastic materials, in contrast to a typical midsole which is formed entirely or to a substantial extent of foamed plastic material.

[0037] The midsole of the present invention is comprised of a base body 2a which is permanently connected to the upper 3, and of a bottom plate 2b which is located below the base body 2a, to the underside of which the outer sole 14 is attached. The bottom plate 2b, here, is formed of two parts 4, 5, specifically, a part 4 in the form of a rear foot bottom plate and a part 5 in the form of a forefoot bottom plate...

Abstract

Shoe (1), especially an athletic shoe, with a midsole (2) and an upper (3) connected to the midsole (2), the midsole (2) having a base body (2a) which is connected to the upper (3), and a bottom plate (2b). To improve the adjustability of the spring properties and/or the damping properties of the shoe sole, it is provided that at least one part (4, 5) of the bottom plate (2b) is connected to the base body (2a) by a hinge at an articulation point (7). Furthermore, at least one spring element (8) is provided between the side of the part (4, 5) of the bottom plate (2b) facing the base body (2a) and the side of the base body (2a) facing the part (4, 5) of the bottom plate (2b). Preferably, one spring is provided in the heel area and a plurality of springs are provided in the forefoot area.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a shoe, especially an athletic shoe, with a midsole and an upper connected to the midsole, the midsole being connected between a base body which is connected to the upper, and a bottom plate (outsole). [0003] 2. Description of the Related Art [0004] A shoe of this type is known from published European Patent Application No. EP 0 552 994 B1 and corresponding U.S. Pat. No. 5,282,325. The upper is connected to the base body. While the midsole is connected to an outsole in the forward shoe area, the base body and the outsole diverge from one another in the shape of a wedge toward the end of the shoe. Between the base body and the outsole in the heel area a torsion spring is disposed between a pair of interior plates and the bottom plate can deflect relative to the outsole by compression of the spring. While the resiliency of the shoe sole can be influenced via a spring insert of this type, it is...
