となつている。 Among the sports shoes that are generally called athletic shoes, sports shoes such as running shoes, sports shoes, baseball shoes, soccer shoes, and various court shoes are currently entering a so-called functional war. In the world of sports, the driving environment has become urethane ground, roads have become asphalt,
Tennis courts are being replaced with hard courts, indoor stadiums are being replaced with plastic, and baseball fields are being replaced with artificial turf. Sports athletes are required to take on tough challenges to improve their speed and break records, and demands and expectations for more advanced functionality in various sports shoes are increasing. In order to meet this demand, there is an urgent need to develop functional parts for advanced sports shoes.
本考案者らは、これらの要望や期待に応えるた

即ち本考案は次の通りである。 In order to meet these demands and expectations, the inventors of the present invention investigated various materials for sports shoes and found that it would be effective to use a special polyurethane resin with certain physical properties for specific parts of sports shoes. After discovering this, we came up with this idea.
That is, the present invention is as follows.

There are 183722. Among these, those having shore hardness in the range of 30 to 70 and rebound resilience in the range of 0.5 to 40% are effective. These include some that contain bubbles and some that do not. As for its chemical structure, the equivalent weight of the organic polyisocyanate is 1 or less, so the OH groups of the polyol present in excess are liberated in the polyurethane elastomer. This branching of the polyol with free OH groups has a plasticizing effect, making the polyurethane elastomer ultra-soft.
