  • Patent number: 4707874
    Abstract: The invention relates to a method of waterproofing an article of footwear, for example, a boot, and the article of footwear produced therefrom. To waterproof the article a solution of effective amounts of a polymeric material and solvent is applied to inner surface areas of the article sought to be waterproofed. The solution is then substantially dried to produce a layer of a waterproof polymeric material over the surface of selected areas of the inside of the article. Conveniently and efficiently the layer of solution may be applied to the inner surface of the article by transferring a quantity of the solution into the article until the article is filled to the desired level (e.g. upper ankle level) and therafter orienting the article appropriately to cause the solution to spread to all inner surface areas of the foot portion of the article. Following this the excess solution is removed from the article by tilting the article causing the excess solution to drain out of the article.
