To effectively prevent sand grains, etc. from penetrating into any space between the friction body and the holder, and in turn, to prevent difficulties in undoin g the fitting, damages to the holder or the friction body given by fitting undoing operatio n, and injuries by strained operation. An inner circumference side annular groove S1 is formed in an inner circumference edge part of a golf shoe sole S of a synthetic rubber, an outer circumferenc e side annular groove S2 is formed in the radial outside of the annular groove S1, and an annular packing protrusion S3 is formed between them. An inner circumference side annular ri b R1 is provided on the lower face of the base 14a of the friction part 14, an outer circumference side annular rib R2 is provided in the outer circumference edge part thereof , and the area between them is made an annular packing face 14b. When the friction body 16 is fitted in and held by the holder 10, the inner circumference side annular rib R1 and t he outer circumference side annular rib R2 fit in the inner circumference side annula r groove S1 and the outer circumference side annular groove S2, respectively, and the annular packing protrusion S3 tightly and elastically contacts and presses the annular packi ng face 14b over the entire circumference.
