Abstract

PURPOSE:To prevent an outsole from being deformed by repeated loads for a long time caused by body weight from landing to off land during running by forming a polymer elastic tape with hardness over a specified temperature range based on a prescribed reference vulcanized rubber test method around the side face of the outsole and the outside lower peripheral edge of a vamp. CONSTITUTION:This shoe is composed of an outsole 1 made of an ethylene-vinyl accetate copolymer foam and a vamp 2 to be mounted above the outsole 1. Then, the polymer elastic tape with the hardness of 80 deg.C-100 deg.C based on the JIS and the K6301 vulcanized rubber test method is formed around the side face of the outsole 1 and the outside lower peripheral edge of the vamp 2. Thus, the outsole 1 can be prevented from being deformed by the repeated loads for a long time caused by the weight from loading to off land during running.

ない。以下、更に詳述する。When an EVA foam outer sole is used for a shoe, the shoe is easily deformed if the weight, that is, the load is repeatedly applied during wearing. If such a state continues for a long period of time, the deformation cannot be restored and the product is distorted and the appearance is deteriorated, which is not preferable from the viewpoint of foot health. The details will be described below.

る。When walking or running while wearing shoes, the landing starts from the outside of the heel first, and the load due to the total weight is applied to that part. After that, the load gradually shifts to the inside of the heel and the outside of the non-step part. ， Go to the toe part through the outside of the stepping part and take off by kicking out. When such a state during walking is repeatedly performed for a long period of time, the outer side of the heel of the EVA foam is compressed and becomes thin, and at the same time, when viewed from the back, the entire heel of the outer side is outward or The state is shifted inward. Continuing to wear such shoes will cause the wearer to wear them in an abnormal state, damaging the heel and heel joints,
Not good for your health. The present invention is also aimed at overcoming the abovementioned drawbacks of shoes having an EVA foam outsole.

This acts as a pillar, and for example, there is no deformation due to repeated load of the outer sole (1) due to the weight from landing to departure during running for a long period of time, and therefore no distortion. Due to such an action, the wearer's foot is always kept in a normal state during wearing, and the wearer can wear it comfortably without damaging the joint. Of course, the lightness and cushioning properties of the outer bottom of the foam are not impaired.
