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.
