Insole and use of the same for producing a shoe

The insole as claimed in one of the preceding claims, characterized in that the means for longitudinal flexibilization of the thickening (5) are indentations (14) in the material of the thickening (5), which run transversely to the longitudinal direction (18) of the insole, so that the thickening (5) has a ladder-like structure.

The insole as claimed in one of the preceding claims, characterized in that the means for transverse stiffening and/or longitudinal flexibilization of the support sole (2) and/or of the thickening (5) are fibers or other longitudinally flexible and/or transversely stiff materials, such as, for example, special graphite or boron fibers, and/or material formations or shapes, such as transverse ribs.

The insole as claimed in one of the preceding claims, characterized in that the means for transverse stiffening and/or longitudinal flexibilization of the support sole (2) and/or of the thickening (5) are materials of different Shore hardness, which are arranged next to one another, running transversely to the longitudinal direction of the sole.

The insole as claimed in one of the preceding claims, characterized in that the means for transverse stiffening and/or longitudinal flexibilization are provided in such a manner that, in the front foot area and if appropriate in the midfoot area, the maximum transverse stiffening runs at an angle α in the range from 77° to 90° to the longitudinal direction (18) of the sole and/or the maximum longitudinal flexibility runs at an angle β from 0° to −13° to the longitudinal direction (18) of the sole, this area of transverse stiffening and/or longitudinal flexibility preferably extending over 30% to 60% of the length of the sole.

The insole as claimed in one of the preceding claims, characterized in that the means (14, 15;

• 16, 17) for transverse stiffening and/or longitudinal flexibilization are provided in such a manner in the rear foot or heel area that the maximum transverse stiffening runs at an angle γ in the range from 90° to 103° to the longitudinal direction (18) of the sole and/or the maximum longitudinal flexibility runs at an angle δ from 0° to 13° to the longitudinal direction (18) of the sole, the area of transverse stiffening and/or longitudinal flexibility preferably extending over 20% to 40% of the longitudinal direction (18) of the sole.

The insole as claimed in one of the preceding claims, characterized in that the dish edge (4) is provided with means, preferably notches or wedge-shaped incisions (14), which prevent a resistance effect and/or a throwing up of the dish edge (4) in the area of the intended bend, in particular of the ball.

The insole as claimed in one of the preceding claims, characterized in that the underside of the support sole (2) in the area of the lasting margin recess (7) is plane-surfaced or smooth.

The insole as claimed in one of the preceding claims, characterized in that the thickening (5) and/or the support sole (2) or the entire insole (1) has a Shore A hardness in the range from 80 to 100, preferably in the range from 85 to 98.

The insole as claimed in one of the preceding claims, characterized in that the entire insole (1) is in one piece or consists of components (2, 4, 5) which are integrated to form a one-piece unit.
