Abstract: The invention relates to a sport shoe and particularly to its midsole construction. The midsole construction comprises a flexible body element, which extends essentially over the entire length of the sole of the foot, a flexible heel element located under the body element, which extends from under the calcaneus at least partly into the area of the cuboid bone, and a plate-like stiffener element located at least partly between the body element and the heel element. According to the invention, the stiffener element extends from the heel area forwards farther on the lateral side of the sole of the foot than on the medial side of the sole of the foot. A more natural and economical stride is achieved with the aid of the invention.

Abstract: A sole structure of a sports shoe includes an outsole and an intermediate sole having a number of portions that is flexible and supports the foot during running. The intermediate sole includes a flexible body element extending along the entire length of the shoe, and a flexible heel absorption element extending to the heel area, and a support element fitted between them extending from the heel area to the ball area which is of a less flexible material than the body element or the heel absorption element. The support element includes a substantially plate-like heel portion and a shaped front portion, which are separated from each other by a substantially cross-directional support ridge protruding from the lower surface of the support element. The intermediate sole also includes an hourglass-shaped ball absorption element, a carbon fiber plate increasing the torsional rigidity of the support element and an arch support.
