摘要

A shock-absorbing innersole for use in footwear, which innersole comprises an innersole body composed of a substantially nondeformable elastomeric-type urethane cellular polymer, having a contoured molded heel and arch section and a substantially flat sheet containing a ball and toe section, the innersole having one or more shock-absorbing inserts in the innersole positioned in the heel, ball or both areas of the innersole, the insert composed of a solid elastomeric polymer which has greater shock-absorbing properties and greater surface tack than the elastomeric urethane of the innersole body.
