The Ragnarok MTN Tall Cycling Boot is one for mild to moderate conditions where we require a shoe that makes riding more enjoyable when it's cold and wet. It could be used for fatbiking with the appropriate kit, but we also think it's a quality performance shoe for inclement weather. Tough microfiber paired with a neoprene ankle cuff keeps out the elements, and a breathable waterproof membrane stops liquid from the outside but allows vapor to be released from the inside. We like this shoe for its durability, warmth, and protection.
