Articles of footwear may include a knitted component defining at least part of a void and joined with a sole structure. The knitted component may include an interior knit layer, an exterior knit layer, and a plurality of inlaid courses of a high tenacity yarn between the interior and exterior knit layers. The plurality of inlaid courses of high tenacity yarn may include at least three courses of the high tenacity yarn, each of which may be separated from an adjacent course of the plurality by no more than five courses.

Textile Components, such as upper members for articles of footwear, include: (a) a first portion having a first edge, wherein the first edge includes a first portion of material engaged with a first seam support material via a first thermoplastic material; (b) a second portion having a second edge, wherein the second edge includes a second portion of material engaged with a second seam support material via a second thermoplastic material; and (c) structure to engage the first and second edges in an abutting edge joint (such as a zig-zag stitch). The resulting textile components may be lightweight and breathable (e.g., due to use of lightweight upper fabric), having a comfortable fit (e.g., due to the abutting edge joint), while still providing a strong, stable, and durable construction (e.g., due to the presence of the seam support member(s)).

A sole structure includes a mid-foot region, a heel region, a lateral side and a medial side is provided. The sole structure has a first sole element including a first inner surface having a plurality of first surface features, whereby at least one of the first surface features has a different configuration than another one of the first surface features. The sole structure further includes a second sole element including a second inner surface having a plurality of second surface features configured to interface with the first surface features. A panel is disposed between the first sole element and the second sole element, such that the sole element is disposed on a first side of the panel and the second sole element being disposed on a second side of the panel, opposite the first side.

A slipper that is an assemblable slipper is proposed. The slipper is assembled without use of an adhesive, used with any design as desired by the user, and is easy to carry. The slipper can be assembled, without use of an adhesive by inserting a band into a sole portion and fixing the band with a bed. In effect, when the slipper is carried or is not in use, a space for carrying can be reduced by separating the band from the sole portion, and it is also easy to react to damage or separation of the band. In addition, as it is easy to replace the band, the slipper can be easily replaced with a design as desired by the user. In this regard, the present invention is effective in extending the life of the slipper as a result of replacement of the band.

A shoe, comprising a sole and a shoe upper, wherein the sole comprises a sole part which has a base region from which at least one support part extends upwards during the intended use of the shoe, wherein the shoe upper comprises a sock-like section connected to the sole for receiving the foot of the wearer. To obtain improved contact of the shoe with the foot of the wearer, the at least one support part covers the sock-like section on the shoe outer side, wherein no firm connection exists between the support part and the sock-like section over at least a section of the support part and that both the at least one support part and the sock-like section are surrounded by a tensioning element which tensions at least some sections of both the support part and the sock-like section against the foot of the wearer of the shoe.

An orthotic footwear system including a removable outsole, a removable reinforced hollow midsole attached to the top of the outsole, and a removable insole attached to the top of the midsole. A removable metatarsal pad can be attached to the top of the insole, and removable support inserts can be attached around the insole for additional support of problematic areas. Support inserts can be used to support the arch area, the heel area, or both. Each of the removable parts can be interchanged with parts of the same type having different ergonomic characteristics. The user can change the parts of the orthotic to suit their needs. Further, the support inserts can be used apart from the rest of the system, with any insole configured to receive them.

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.
