PROBLEM TO BE SOLVED: To provide a method for arranging projecting spots in golf shoes 3 which are excellent in antiskid property. SOLUTION: The method for arranging the projecting spots comprises a step for measurement of floor reaction force in the horizontal direction and in the vertical direction during a golf swing by an instrument 5 for measuring three-dimensional floor reaction force, a step for calculating the ratio of a horizontal load to a vertical load, a step for determining a peak moment which is the moment when the ratio comes to the maximum, a step for determining a starting moment when the ratio lies under a rising stage toward the maximum and that the ratio comes to 60% of the maximum, and an ending moment which is the moment when the ratio lies under a falling stage from the maximum and that the ratio comes to 60% of the maximum, a step for arranging horizontal components vectors of three-dimensional floor reaction force, with original points of the vectors concentrated at one point, at specified intervals between the starting moment and the ending moment, a step for supposing a reference lien which is a line connecting front ends of the vectors, and a step for determining the projecting spots so that side walls line up along the reference line.
