These winter boots will keep your kids playing in the snow way past dinnertime. They're waterproof and warm, with a nylon upper and cozy fleece lining. The Frosty is also insulated with 200g Thermolite to keep kids' toes toasty down to a chilly -25 degrees F. A sturdy TPR bottom with All Terrain Grip lugged outsoles offer up protection and traction in the biggest of snow piles. The Frosty stays snug with a loop strap around the ankle, and a nylon toggle at the top helps keep the snow out.
