Abstract:
A sports shoe having a heel counter with a heel reinforcement wall shaped to include an inner surface which is in conformity with an outer surface of a heel portion of an upper of the sports shoe. An attaching portion is formed to project inwards from a lower end portion of the heel reinforcement wall. A flange portion formed to project outwards from the lower end portion of the heel reinforcement wall is provided in such a manner that the inner surface of the heel reinforcement wall is adhered to the outer surface of the heel portion of the upper. The attaching portion thereof is interposed between and adhered to an inwardly bent portion of the upper portion and a shoe sole. The flange portion thereof is adhered to an upper surface of an outer peripheral edge portion of the shoe sole. In this manner, the heel portion is prevented from rolling during running and the heel counter is prevented from peeling off.
