This Kuling Engelberg winter boot is waterproof footwear with a 100% waterproof membrane that keeps feet dry while allowing breathability for snowy play. This wide-fit design in both shaft and foot offers extra room for warm socks and freedom to run, jump, and explore. This boot features a super soft wool-mix lining (70% polyester, 30% wool) and a removable insole for easy airing after a day outside. This durable TPR outer sole and grippy tread deliver reliable traction on slippery surfaces while the 100% polyester outer resists snow and moisture for long-lasting wear.
