ABSTRACT:
Method of bonding a sole to a shoe by applying moisture-curable melt adhesive to the shoe upper, subjecting the adhesive coating to a hot-cure step with airborne moisture, and pressing the sole and shoe upper together with the adhesive between them immediately after the hot-cure step, preferably in less than 90 seconds after leaving the hot-cure. The bond is effected without application of adhesive to the sole, which is merely pre-treated by wiping with solvent or primer solution.
