The Kids’ Fastpack Hiker Mid Waterproof Boots are ankle-high trail shoes that are durable and comfortable. They have cushioned, slightly rockered midsoles that are designed to help power junior explorers to their destination. 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.
