A shoe including a sole and an upper. The upper is coupled to the sole. The upper includes an outer layer and an inner layer. The outer layer has an outer surface and an inner surface. The inner surface of the outer layer is in direct contact with the inner layer. The outer layer is a hot melt thermoplastic material, and the inner layer is a material different from that of the outer layer. At least a portion of the outer layer is adhered to the inner layer, and the inner layer including a portion not covered by the outer layer.

A footwear item includes an insole, an outsole, and a midsole. The insole includes an insole top surface, an insole bottom surface, and an insole sidewall. The outsole includes an outsole top surface and an outsole bottom surface. The midsole is positioned between the insole and the outsole. The midsole is configured to nest onto the top surface of the outsole. In at least the heel region, the midsole includes a strobel upper surface and a strobel sidewall configured to nestingly receive a heel region of the insole. In addition, an interface between the strobel upper surface and the strobel sidewall includes a fillet region configured to support and reduce lateral-medial movement of the insole relative to the midsole.

A disposable overshoe preferably made from a single-ply sheet of waterproof material folded on top of itself to form a double ply-sheet with a fold at the bottom. The toe of the disposable overshoe can be made by fusing the double-ply sheet to itself to form a toe-side connection running from the fold at the bottom to an opening between the double-ply sheets at a top. Likewise, the heel of the disposable overshoe can be made by fusing the double-ply sheet to itself to form a heel-side connection running from the fold at the bottom to the opening at the top. By orienting and forming the toe-side and heel-side connections to the size and shape of a shoe, an opening at the top can be left to allow a shoe to fit between the opening in the double-ply sheet. In this way, a user can insert the toe of the user's shoe into the opening, and cinch a strap around the user's leg to protect the inside of the disposable overshoe from the outside elements.

A junction line data generation method includes scanning a first junction component and a second junction component by using an image capturing device for generating three-dimensional first junction component modeling data of the first junction component and generating three-dimensional second junction component modeling data of the second junction component, simulating a first junction component structure by using the three-dimensional first junction component modeling data, simulating a second junction component structure by using the three-dimensional second junction component modeling data, and generating junction line data between the first junction component and the second junction component by optionally deforming the first junction component structure and/or the second junction component structure according to the first junction component structure and the second junction component structure.

The present application discloses footwear comprising a body structure in which at least upper is made of one continuous folded composite material comprised of layered sheets of material.
