Abstract: Embodiments of the present invention relate to an article of footwear having a unitary upper and midsole referred to as a midsole-upper. The midsole-upper includes both a midsole portion and an upper portion. An outsole may be coupled to the midsole portion to provide a ground contacting surface. Additionally, a bootie may be coupled to the interior of the midsole-upper. A reinforcement may be utilized in conjunction with the midsole-upper and/or the bootie to resist lasting deformation of apertures formed into the midsole-upper for a lacing structure. The reinforcement may be coupled to the bootie, the midsole-upper, or other portions of the shoe. In an embodiment, the reinforcements are constructed from a material different from that which the midsole-upper is formed. Consequently, a traditional crisscross lacing pattern may be utilized while still realizing benefits of having a unitary upper and midsole.

Abstract: Methods for making footwear products include: (a) applying cement to a surface of an upper and/or midsole; (b) cooling the upper and/or midsole so that these parts will move relative to one another despite the cement's presence; and (c) placing the midsole in the upper. Additional methods include: (a) providing an upper having an interior chamber; (b) placing a prelast member including a midsole allowance part into the chamber; (c) removing the prelast member; and (d) placing a midsole in the chamber. The upper and/or midsole may have cement applied thereto and may be cooled before the insertion step, as described above. When sufficiently cooled, the cement will not immediately bind the parts contacting it, but it will allow relative movement of these parts. After the midsole is positioned in the upper, the assembly may be heated to activate the cement and fix the parts together.

Abstract: Embodiments of the present invention relate to an article of footwear having a unitary upper and midsole referred to as a mupper. The mupper includes both a midsole portion and an upper portion. An outsole may be coupled to the midsole portion to provide a ground contacting surface. Additionally, a bootie may be coupled to the interior of the mupper. A reinforcement may be utilized in conjunction with the mupper and/or the bootie to resist lasting deformation of apertures formed into the mupper for a lacing structure. The reinforcement may be coupled to the bootie, the mupper, or other portions of the shoe. In an embodiment, the reinforcements are constructed from a material different from that which the mupper is formed. Consequently, a traditional crisscross lacing pattern may be utilized while still realizing benefits of having a unitary upper and midsole.
