Midsole having a clear free space

Abstract

A shoe sole (1) includes a stability support plate (3) and a soft elastic midsole (2) having a forefoot area (VFB), a midfoot area (MFB) and a heel area (FB). The stability support plate is peripherally surrounded by the midsole and the midsole (2) has a clear space (21) open to the bottom side (U) of the midsole (2), which is peripherally surrounded substantially completely by the midsole (2) and is delimited by the stability support plate (3). The clear space (21) extends from the heel area (FB) over the midfoot area (MFB) into the forefoot area (VFB) of the midsole (2).
