Abstract

See full text

A midsole structure for a shoe not only maintains stability at the time of impacting the ground and improves cushioning property but also eliminates discomfort to a foot sole and improves ride feeling during running. The midsole structure (1) comprises at least two midsoles provided at a heel region of the shoe and having a hardness difference. On opposite sides of the heel region, an upper midsole (2) of a greater hardness has a thickness greater than a thickness of a lower midsole (3) of a smaller hardness. In a central part of the heel region, the lower midsole (3) of a smaller hardness has a thickness greater than a thickness of the upper midsole (2) of a greater hardness. Boundary surfaces (2B, 3A) between the upper midsole (2) and the lower midsole (3) do not appear on a top surface of the midsole structure (1) (that is, a foot sole contact surface (2A) of the upper midsole (2)).
