Footwear and method of making footwear

A method of making footwear including at least an outsole side constituent body constituting an outsole side, an upper side constituent body constituting an upper side, screw receiving seats, and coupling screws screwed thereinto, the method comprising:

• in the outsole side constituent body, providing a plurality of outsole side mounting arrangement portions at predetermined intervals for mounting and arranging the screw receiving seats or the coupling screws;
• in the upper side constituent body, providing a plurality of upper side mounting arrangement portions at predetermined intervals, corresponding to the outsole side mounting arrangement portions, for mounting and arranging the screw receiving seats or the coupling screws;
• screwing together the coupling screws and the screw receiving seats mounted and arranged in pairs on the outsole side mounting arrangement portions and the upper side mounting arrangement portions to separably integrate the outsole side constituent body and the upper side constituent body;
• and
• providing a misalignment region in which positions of the outsole side mounting arrangement portions and positions of the upper side mounting arrangement portions are displaced from each other to cause, in the case of screw-coupling the outsole side constituent body and the upper side constituent body, a curved shape to be formed in the misalignment region according to a displacement direction and a displacement dimension therein.
