PROBLEM TO BE SOLVED: To provide a nonskid attachment which facilitates safe walking on a road surface frozen by an snowfall and the cold of the wintertime by installing the nonskid attachment on ordinary habitually wearing various shoes and easily usable in a required place by carrying the nonskid attachment throughout the year. SOLUTION: Respective parts of a front tread part, a plantar arch part, a heel part and a column part are installed on the shoes by stoppers 2 and 9 in the shape of binding a toe and a heel of the shoes by using extensibility- contractibility, resiliency, flexibility and nonskid performance of rubber. A groove is applied to the whole surface of thickened front and rear tread parts to impart nonskid performance and flexibility. Plural spike rivets 11 are embedded in the most tread part so that the tip of a pin becomes the same as a tread surface or the slightly inside.
