Abstract: An upper includes an upper body covering the instep of a foot. At least a part of the upper body is an opening region disposed with an opening. In the opening region, a plurality of first members extending in one direction is disposed in a state of not being coupled with each other. Both ends of the plurality of first member are fixed ends fixed to a portion of the upper body adjacent to the opening region. The order in which fixed ends on one end side of the plurality of first members are arranged is equal to the order in which fixed ends on the other end side of the plurality of first members are arranged.

Abstract: An upper includes an upper body covering the instep of a foot. An upper body includes a first layer, a second layer disposed with a gap from the first layer, and a third layer connecting the first layer and the second layer. A part of the upper body is disposed with a low stiffness region having lower stiffness than an adjacent region. At least a part of the low stiffness region has a point in which the third layer is not disposed. A plurality of holes is disposed in at least a part of a portion of the first layer and the second layer of the low stiffness region corresponding to the point in which the third layer is not disposed.

Abstract: An upper provided with an opening includes a first side edge, a second side edge, a first forming portion that protrudes from the first side edge toward the second side edge, a second forming portion that protrudes from the second side edge toward the first side edge, an outer foot side string passing portion including one first string passing portion and one second string passing portion as one set, and an inner foot side string passing portion including one third string passing portion and one fourth string passing portion as one set, and a shoelace. The first forming portion and the second forming portion are alternately provided in a fore-rear direction. The shoelace includes a first portion alternately passed through the second string passing portion and the third string passing portion, and a second portion alternately passed through the first string passing portion and the fourth string passing portion.

Abstract: An upper includes an upper main body covering an instep of a foot. The upper main body is formed with a partial region that is a region away from an outer edge of the upper main body, and a passage formed in a tubular shape that extends from the partial region toward the outer edge and then extends so as to return to the partial region and allows a shoelace to pass through. An opening extending in a front-back direction is formed in the partial region. The passage extends from the opening toward the outer edge and then extends so as to return to the opening.

Abstract: An article of footwear includes a sole and an upper. The upper includes a single fabric portion including a base layer having breathability. The single fabric portion includes: a strength portion including the base layer, a breathable layer, and a strength layer; and a breathable portion including only the base layer or only the base layer and the breathable layer. The base layer has a shape extending from a toe region located at a front end in a longitudinal direction of the article of footwear to reach a heel region located at a rear end thereof. The strength portion includes: a toe strength portion disposed in the toe region; and a heel strength portion disposed in the heel region. The breathable portion includes an intermediate breathable portion disposed in an intermediate region located between the toe region and the heel region.

Abstract: An article of footwear includes a sole and an upper. The upper includes a restrictive fabric portion. The restrictive fabric portion includes elastic and restrictive strands. A restrictive-side resistance index is greater than an elastic-side resistance index, when a tensile load is applied to the restrictive fabric portion in a direction of stretching the elastic and restrictive strands, where the restrictive-side resistance index is a ratio of an increase in tensile stress to an increase in rate of stretch of the restrictive strand, in a range in which a rate of stretch of the restrictive fabric portion is greater than a predetermined value, and the elastic-side resistance index is a ratio of an increase in tensile stress to an increase in rate of stretch of the elastic strand, in the range in which the rate of stretch of the restrictive fabric portion is greater than the predetermined value.

Abstract: An upper includes an upper main body that covers an instep of a foot. The upper main body includes: a first portion including a plurality of linear bodies and formed by one layer; and a bag-shaped second portion formed by two layers in which some of the plurality of linear bodies constituting the first portion serve as one layer and the rest of the plurality of linear bodies serves as another layer. Inside the second portion, a cushioning material is put. The second portion protrudes toward a foot of a wearer with respect to the first portion.
