PROBLEM TO BE SOLVED: To suppress the slip of an outsole of shoes on a wet floor surface by making an outsole out of a vulcanized molded product of a rubber composition that comprises a diene rubber containing a clay whose major component is kaolinite and a silane coupling agent in specified amounts respectively. SOLUTION: An outsole 2 is made out of a vulcanized molded product of a rubber composition comprising 100 pt.wt. diene rubber, 10 to 40 pts.wt. clay whose major component is kaloinite, and 0.1 to 15 pts.wt. so that the outsole 2 itself may be made water-repellent. If the content of the clay is less than 10 pts.wt. per 100 pts.wt. diene rubber, the effect of making the outsole water- repellent cannot be exhibited satisfactorily whereas if the content of the clay is less than 40 pts.wt. per 100 pts.wt. diene rubber, the tear strength and the like are lowered. Thus, an outsole of a shoe that is excellent in wet gripping properties on a wet floor surface and is hard to slip even on a wet floor surface can be obtained.
