The Kamik Kids' Luke EZ Winter Boots are ready for snow days, icy hills, and nonstop winter play. Durable nylon with polyurethane trim helps the boots handle active outdoor adventures while the waterproof rubber base and outsole keep little feet dry through slush and snow. Soft fleece and faux shearling lining provide cozy warmth for comfortable play in cold conditions. The easy hook and loop closure makes getting ready quick and mitten friendly. An EVA insole adds cushioned support underfoot for active days. With a cold weather rating down to -40F, these boots are built to keep up when winter conditions get seriously cold.
