Abstract: Described herein is a footwear and an article for keeping a foot dry, and a related method. A footwear member may have an exterior surface defining an exterior of the footwear member, an internal surface defining an internal cavity sized to receive the foot and at least portions of the removable membrane, and a footwear size. The removable membrane may be made of a non-rigid, disposable, resilient material that is impermeable to water. The removable membrane may have a membrane exterior surface, a membrane interior surface, and a membrane size corresponding to the footwear size. The removable membrane configured to conform to a shape and a size of the foot. The method may include providing a footwear assembly including a footwear member and a removable membrane, placing the provided membrane over the foot, and positioning the removable membrane with the foot inserted therein within the boot.

Abstract: An article for keeping a foot (and potentially a sock) dry, when placed within a boot, the article comprising a non-rigid membrane impermeable to water and disposable material, and conformed to the shape of the foot so that there is little or no excess material when the article is placed over the foot (and potentially the sock, and both are) placed within the boot. The article may comprise a toe section, heel section, lower leg section, top opening, and a means for preventing the lower leg section and the top opening from falling down. Notwithstanding its disposability, the material comprising the article may be sufficiently resilient and durable for withstanding the frequent and substantial forces that the boot and foot may be subjected to during a work day at a wet construction site. The article may also allow continued use of a punctured previously-waterproof boot without the foot becoming wet.
