The Kamik Luke EZ Winter Boot is designed for active, adventurous kids who won't let winter weather keep them indoors. Constructed with a durable 600D nylon upper and polyurethane trim, these boots can withstand snowy escapades, icy sidewalks, and salty streets. A waterproof synthetic rubber shell and outsole ensure dry feet, even during full-contact snow play. With a soft fleece and faux-shearling lining, these boots offer superior warmth and comfort. The boot's quick-use hook-and-loop strap with a bungee closure makes dressing easier, even with mittens on. And with a Ground-Ctrl Rubber outsole made from flexible, recycled PVC-free rubber, your little ones get dependable traction, even in the chilliest temperatures.
