Midsole structure for sports shoes and molding method thereof

Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 各種競技種目に応じて競技者の着地時の横振 れを防止して、過回外および過回内を抑制し、しかも着 地時のクッション性確保と競技力の低下防止とを両立さ せる。 【解決手段】 スポーツ用シューズのミッドソール構造 において、軟質弾性部材から構成されるミッドソール３ 内の少なくとも踵部分に波形シート４を介在させるとと もに、波形シート４の波形状の振幅Ａおよび波長λの少 なくともいずれか一方を踵部分の前，後端部間あるいは 内，外側部間の少なくともいずれか一方で異ならせる。 たとえば、波形シート４の踵部分内側部側の振幅Ａ i を 踵部分外側部側の振幅Ａ o よりも大きくし、踵部分内側 部側の波長λ i を踵部分外側部側の波長λ o よりも大き くする。 (57) [Summary] [Problem] To prevent the athlete from swaying at the time of landing according to various competitions, to suppress over-return and over-return, and to ensure cushioning and competitive power at the time of landing. Balance with prevention of lowering. SOLUTION: In a midsole structure of a sports shoe, a midsole 3 composed of a soft elastic member is provided. The corrugated sheet 4 is interposed at least in the heel portion of the heel portion, and at least one of the amplitude A and the wavelength λ of the corrugated shape of the corrugated sheet 4 is set at least between the front and rear ends of the heel portion or between the inner and outer portions. Or make it different. For example, the amplitude A i of the inner side of the heel portion of the corrugated sheet 4 is made larger than the amplitude A o of the outer side of the heel portion, and the wavelength λ i of the inner side of the heel portion is made larger than the wavelength λ o of the outer side of the heel portion. Also increase.
