Abstract

The outsole (1, 3), particularly for sports shoes (2), can be provided with a high degree of elastic deformability in a tangential direction thereby achieving a good cushioning even when the shoe strikes the ground with a slanted and somewhat sliding impact. The invention provides that the outsole (1), beyond at least one critical deformation in the area deformed thus far, is, however, essentially stiff with regard to tangential deformation. This provides the runner with a more sure footing on the respective impact or loading point. The runner can push off once again from the loading point also without losing ground. A floating effect on the sole is thus prevented. The sole can, as a whole or in several parts, also be detachably fastened to a middle sole (4) of the shoe (2).

Description

Outer bottom

Technical field

The present invention relates to a kind of outer bottom of particularly using that also has strain in tangential direction for sport footwear.

At this, the distortion of tangential direction for example be interpreted as by shearing cause with the distortion of the tangent or parallel direction of the outer surface of the plane of outer bottom or outer bottom.Different with this distortion is for example by compression cause with the distortion of the direction of the outer surface quadrature of the plane of outer bottom or outer bottom.On the level basis, tangential direction roughly overlaps with horizontal direction, and orthogonal direction roughly overlaps with vertical direction.

Background technology
