Patent ID: 7060347

Claim:
A sports shoe insert, comprising: an anisotropic bending element comprising at least one reinforcing layer I, each of which contains a fibrous reinforcing component I with a tensile modulus of elasticity in a range of from 1,800 to 20,000 N/mm 2 ; and at least one elastomeric layer II, each of which contains an elastomer and has a tensile modulus of elasticity in a range of from 2 to 1,300 N/mm 2 , wherein a weight ratio in the bending element of the fibrous reinforcing component I to the elastomer is in a range of from 1:99 to 40:60; and when the bending element is bent about an axis parallel to the reinforcing layer I, a ratio of a rigidity of the bending element in a positive direction of rotation relative to a rigidity of the bending element in a negative direction of rotation is 1: 1.2 or more; wherein said bending element is configured to be insertable into a sports shoe.
