Whether they’re shoveling snow or planning a tobogganing mission, Kamik guarantees the warmth of your child’s feet in the Big Kid’s GLACIAL 3 Winter Boots. These extremely warm boots are certified for use in -50C thanks to removable (and washable) 9mm thick Zylextra insulation liners. Protecting the liners are uppers constructed with ballistic nylon. The lightweight shells and outsoles provide 100% water- and- snowproof protection, along with stable grip on icy playgrounds and driveways.
