Lightweight sole with good grip, waterproof construction and full adjustability for the best fit - a bunch of awesome features in one pair of shoes. Waterproof Reimatec shoes are made of synthetic material and textiles and the outsole is thermoplastic rubber. Seam-sealed insert, mesh lining and to help to find the correct size removable Happy Fit insoles. These shoes are perfect for both outdoors and school days, and after an adventure, you can put these in the washing machine (delicate cycle) and they are as good as new again!
