Standing for "The Tree of Life" in Nordic mythology, this is a classic style in its original clog version, rooted at the center of the El Naturalista universe. Pull-grain leather upper is treated with river stones to temper the hide naturally, which gives it an attractive rustic look but is softened until optimal comfort is reached. Thick & sturdy hand-stitched accents present a distinct feature in every style. Anatomically-correct insole made from recycled cork allows breathability & shoe hygiene. Recycled footbed is contoured to the natural shape of the foot for lasting comfort. Recycled, high-quality rubber, which contains a scent of tea tree oil, is used for these unique outsoles.
