PROBLEM TO BE SOLVED: To effectively restrict the deformation of an upper which is caused in side stepping. SOLUTION: An instep belt 1 includes: a first belt member 10 having a start end A, which is fixed to an upper part at a position corresponding to the side surface of a fifth toe proximal phalanx PP<SB>5</SB>bone body in the foot of a wearer, and a terminal end C, which is arranged on the upper part at a position corresponding to a fourth toe metatarsal MP<SB>4</SB>bone head; a second belt member 11 having a start end B, which is fixed to the upper part at a position corresponding to the side surface of a fifth toe metatarsal MB<SB>5</SB>bone body, and a terminal end C, which is arranged at the upper part at a position corresponding to a fourth toe metatarsal MP<SB>4</SB>bone head, and where the terminal end C coincides with the terminal end C of the first belt member 10; and a third belt member 12 which is extended to the upper part at a position corresponding to the side surface of a first toe metatarsal MB<SB>1</SB>bone body with the terminal ends C of the respective belt members 10, 11 as the start ends. The instep belt 1 is arranged to have a substantially Y shape on an upper instep part. COPYRIGHT: (C)2009,JPO&INPIT
