We do not make any shoes with claims to be “waterproof." We do offer several models that are highly water resistant and some that are constructed with waterproof membranes, seam tape and booties, however we do not claim they are waterproof for the following reasons: -The top opening will not make a perfect seal around your ankle or leg -The membrane is designed to cover up to the bottom 2/3 of the shoe. Stepping in water that is above the lower 2/3 portion will allow water to enter. Standing in water will also wash away the coating, allowing the upper material to absorb water. -The upper materials come from our factory with DWR (Durable water resistant) coating that keeps water from being absorbed and migrating into the shoes. However, this coating does wear away over time, especially if the shoes are used in wet conditions. Eventually the DWR will need to reapplied. There are many third party brands who make replacement waterproofing coating sprays that can be found in outdoor or large retail box stores.
