Rubber is organic. It gives unlimited tactile feedback to all parts of your foot. And it has a smooth, predictable, and progressively increasing rate of stiffness in 360 degrees of motion from the center. The Animal Boot is constructed with 100% Natural Thick Rubber. Its Rubber Toe, Heel, and Overlay provide the stiffness skiers need in a slalom boot with the comfort and reliability they desire. The heel cup is further reinforced to increase overall control. Unlike the front boot, the Rear Animal Boot was designed with a THIN rubber overlay for more back boot mobility. Additionally, the Shaped Orthotic Footbed has contoured arch support to your foot’s natural arches for comfort and to enhance your natural motion. The Animals rebuildable design allows you to replace component parts for a long-lasting boot to get you through many epic seasons of intense use.
