The Kamik Boys' Nation JR. Boot is so classy and durable that it holds strong as your explorer builds snow forts and snowmen. To keep his feet dry as he plays, the waterproof suede and 600D nylon upper combines with the taped seams to block snow from seeping in. A removable 3M Thinsulate liner offers toasty protection while the textile lining wicks away moisture, which helps prevent clamminess. The Nation JR. Boot also features a Kamik PIONEER rubber sole that provides necessary traction to fend off snowball ambushes.
