<P>PROBLEM TO BE SOLVED: To provide a sports shoe substantially reducing, or even eliminating, the occurrence of injuries in the area of the user's feet or legs, and further providing more comfort when used. <P>SOLUTION: A sole (2) includes a contact surface (8) having the first support portion (31). The first support portion includes a first subdivision (32) extending along a tip (5) from a lateral side (6) to a medial side (7), as well as a second subdivision (33) extending in a direction of a rear end (4) from the first subdivision and in a direction of the medial side included in a metatarsal zone (23) from the lateral side. The contact surface has a second support portion (34) which extends from the first subdivision (32) of the first support portion towards the rear end (4) and from the second subdivision (33) of the first support portion towards the medial side included in the metatarsal zone (23). The average coefficient of friction of the first support portion is greater than the average coefficient of friction of the second support portion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
