Claim:
A sports shoe suitable for exercise, comprising: a sole absorbing a shock of landing, an upper covering an instep of a foot, and a fastening member fitting the upper to the instep of the foot, wherein the upper has a first opening from which a leg extends upwardly during wearing and a second opening which is closed with a tongue covering the instep of the foot, and the first and second openings are continuous with each other in a front-rear direction, wherein the upper comprises: a first shape-retaining region covering at least a medial side surface of a ball of a big toe; a second shape-retaining region covering at least a part of a proximal phalanx of a third toe; and a deformation region being located anterior to the second opening between the first and second shape-retaining regions and being easier to deform than the first and second shape-retaining regions, wherein the first and second shape-retaining regions come closer to each other by a fastening force applied by the fastening member and a main member forming the upper in the deformation region shrinks in a width direction of the foot by the fastening force, a center line of the second opening inclines toward a medial side of the foot along a ridge line of the instep of the foot as it extends toward a front of the foot, the deformation region is continuous with the second opening, and a center line of the deformation region inclines toward the medial side of the foot as it extends toward the front of the foot from a front end of the second opening, and the deformation region extends to at least one of an interphalangeal joint of the big toe and an interphalangeal joint of a second toe, the upper further has a plurality of first through-holes and a plurality of second through-holes, and the fastening member consisting of a shoe lace is inserted into the first and second through-holes, the first through-holes line up, along an edge of the second opening, more medially than the edge of the second opening, the second through-holes line up, along the edge of the second opening, more laterally than the edge of the second opening, and a first distance, along the width direction of the foot, between a forefront first through-hole of the first through-holes and a medial end of the shoe is smaller than a second distance, along the width direction of the foot, between a forefront second through-hole of the second through-holes and a lateral end of the shoe.
