Abstract
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 () 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 () of a greater hardness has a thickness greater than a thickness of a lower midsole () of a smaller hardness. In a central part of the heel region, the lower midsole () of a smaller hardness has a thickness greater than a thickness of the upper midsole () of a greater hardness. Boundary surfaces (B,A) between the upper midsole () and the lower midsole () do not appear on a top surface of the midsole structure () (that is, a foot sole contact surface (A) of the upper midsole ()).
