Abstract
Method for waterproofing a welted footwear construction. The footwear includes an insole rib joined to an insole. The method includes applying a sealant gel to the outer surface of the insole rib and attaching a welt and an upper to the rib by stitching with a needle. The needle carries the sealing gel into and through the needle holes formed thereby forming a water impermeable seal between the welt, the upper and the rib.
