Sorel's original boot for deep snow activities is not only for adults. Youth Caribou is built in the same way as the adult model with fully waterproof nubuck leather on the upper part and a 9 mm washable inner lining with a handy snow cuff at the top. The bottom of the boot is handmade in vulcanized rubber and the outsole has been manufactured in Sorel Aero-trac non-slip rubber sole.
