Claims

[Scope of Claim for Utility Model Registration] (1) A multilayer shoe sole consisting of at least an upper sole and a lower sole, the lower sole has a ground contact surface, and the upper sole is layered and integrally formed with the lower sole. The heel of the lower sole is provided with a concave portion that is recessed toward the upper sole, and the upper sole is provided with a protrusion that protrudes from the concave portion of the lower sole toward the ground plane, and the end surface of the protrusion is separated from the ground plane. A multilayer shoe sole in which the density of the material forming the lower sole is greater than the density of the material forming the upper sole. (2) The density of the upper sole is 0.30 to 0.50 g/c
m ³ and hardness (JIS A) of 30 to 40, and the density of the lower sole is 0.70 to 1.00 g/cm ³ and hardness (JIS A) of 60 to 70. Multi-layer sole. (3) The multilayer shoe sole according to claim 1, further comprising a gap recessed toward the upper sole between the concave portion and the protrusion, along the periphery formed by the bottom surface of the protrusion on the ground-contacting surface side together with the protrusion.
