The Kamik Seeker Fur boot adds a layer of faux-shearling to the fleece lining, giving it noticeably more warmth and coziness than a standard lining alone through long days outside. Adjustable bungee laces with an inside zipper still get the boot on fast, and a waterproof Dri-Defense membrane keeps slush and puddles out down to -10degF. The nylon and polyurethane upper stands up to the same backyard snowbanks and muddy driveways as the rest of the Seeker line, just with extra warmth built into every step. What Our Gearhead(R) Experts Are Saying:"My kid's feet stayed noticeably warmer in these than in their old boots, even after an hour of sitting in the snow building a fort instead of moving around. That extra lining actually holds heat instead of just looking cozy."
