Abstract

PROBLEM TO BE SOLVED: To provide sports shoes and an insole having extremely excellent shock absorbability and repulsiveness. SOLUTION: A notch part is formed in the heel part and/or toe part of the mid-sole of sports shoes and filled with a cushioning material comprising foam formed from a mixture of 60-80 weight % of an ethylene/octene copolymer and 20-40 weight % of an ethylene/vinyl acetate copolymer. An insole is formed from the cushioning material.

The cushioning members 7 (7a, 7b) are obtained by subjecting a mixture of an ethylene-octene copolymer and an ethylene-vinyl acetate copolymer to a foaming treatment by adding a foaming agent. As the ethylene-octene copolymer, those produced by the method disclosed in JP-A-6-306121 are preferable. The mixing ratio of the ethylene / octene copolymer and the ethylene / vinyl acetate copolymer is set to 60 to 80% by weight of the ethylene / octene copolymer and 20 to 40% by weight of the ethylene / vinyl acetate copolymer. If the mixing ratio of the ethylene / octene copolymer is more than the above range, the moldability deteriorates, while if it is less than the above range, the impact absorption and resilience decrease.
