The Men’s Bergen Mid Waterproof Boots, our new heritage-inspired outdoor boots with HEATSEEKER™ insulation, are great for everything from walking the dog to biking when it’s cold outside. Our waterproof footwear incorporates a variety of advanced waterproofing materials, treatments, and processes. To help keep feet dry, we use internal waterproof membranes and/or adhesive and seam-seal constructions.
