The sole of this boot supports the body’s centre of gravity during the rolling movement of the foot and absorbs impact with a layer of foam just 2 mm thick. The wearer thus feels the ground intensely, resulting in an activation of muscles and reflex zones. Lacing technology incorporated in the side of the boot supports the arch of the foot. The breathable and water-repellent upper is made from naturally milled new wool and is machine-washable.
