Sole comprising a curved elastic plate

Abstract

A sole for a running shoe comprising a sole tip, a heel edge and a midsole having a base surface delimiting the midsole against the vertical direction (V) and a top surface delimiting the midsole in the vertical direction, wherein the midsole has a heel region (FB), a midfoot region (MFB) and a forefoot region (VFB) and an elastic plate. The elastic plate extends at least from the forefoot region into the midfoot region, and in the forefoot region and/or in the midfoot region has a first curvature with a vertex curved along the longitudinal direction (L) of the midsole in the direction of the top surface of the midsole. The elastic plate is formed so the first curvature is elastically bent in the direction of the base surface by the forces acting during treading and/or rolling movement, and the first curvature returns to its original shape during push-off, or wherein the elastic plate in the forefoot region and/or in the midfoot region has a first curvature curved along the longitudinal direction of the midsole in the direction of the base surface of the midsole and having a vertex. The elastic plate is configured such that the first curvature is elastically bent in the direction of the top surface by the forces acting during treading and/or during rolling movement, and the first curvature returns to its original shape during push-off.
