The SOREL® Caribou Waterproof Boots are designed to keep feet warm, dry, and protected in cold, snowy conditions. They feature a waterproof nubuck leather upper, seam-sealed waterproof construction, and a removable 9 mm washable recycled felt inner boot with a cozy Sherpa pile snow cuff. A bonded felt frost plug midsole provides added insulation, while the handcrafted waterproof vulcanized rubber shell and Aero-Trac non-loading outsole deliver durable protection and reliable traction.
