The Cascade snow boot from Kamik is designed to keep up with their cold-weather play. The boot's seam-sealed waterproof nylon upper and synthetic rubber shell protect them against deep snow and slush, while the 6mm Thermal Guard removable liner locks in warmth down to -40°F. With a bungee lacing system and Easy-Grab lace lock, they can easy slip on and adjust. Plus, it is finished with a deep-tread GripXT outsole for reliable traction.
