PROBLEM TO BE SOLVED: To obtain an antislip rubber material, having a high static friction coefficient, capable of imparting effects such as easy walking even at low temperatures without damaging the floor surface by mixing a granular material having a smaller particle diameter than that of a conventional one in an epoxidized natural rubber, press molding the resultant mixture and then polishing and removing the surface after press molding. SOLUTION: This antislip rubber material is obtained by mixing (B) 30-100 pts.wt. granular material having >=3 Mohs hardness and 40-200μm particle diameter distribution in (A) 100 pts.wt. epoxidized natural rubber with 25-60mol% epoxidation ratio. When the resultant rubber material is used for a shoe sole, etc., at least a part of the surface layer is preferably removed by a machining such as buff polishing to use the machined surface changed into a rough surface as a ground contact surface. Thereby, slipping on snow, a skating rink and ice can be prevented and the material can be used for the tip of a crutch, an antislip of furniture or various gripping materials, etc.
