<p>PROBLEM TO BE SOLVED: To concurrently increase rigidity and flexibility, and alleviate the pain of feet. SOLUTION: A shoe body is tightened via three tightening straps 12, 13 and 14 used for tightening and pressing a split vamp from an upper position, and a shoelace 11 used for tightening the left and right body parts 4 and 5 of the split vamp in a direction for being drawn toward each other. Virtual rotation axes positioned between the root of a toe tip and a foot arch are fixed, so as to keep flexibility in a rotating direction around the axes, and increase rigidity for integration in a lengthwise direction. The right end of the left body part 4 and the left end of the right body part 5 are dislocated inward from the approximate lengthwise center line of the shoe body, so as to avoid the top of a foot instep.</p> |
