<p>A toplift comprising a toplift main body composed of two layers consisting of a soft synthetic resin layer [I] and a hard synthetic resin layer and, projecting from the toplift main body, a mounting pin. The ground contact surface of the toplift consists of the soft synthetic resin layer [I], and the soft synthetic resin layer [I] and the hard synthetic resin layer are joined together by fitting together of projecting and indented portions. As the ground contact surface consists of the soft synthetic resin layer [I], slipping in walking can be prevented. As the junction is made by fitting together, the durability of the toplift main body is excellent.</p> |
