The slip-on alpha cozy is fully lined in our thickest, plushest fleece and made with alpha Construction, combining 4 mm of neoprene wrapped with hand-laid premium rubber for 100% waterproof protection. A flexible back panel and kickoff plate at the heel makes slipping them on and taking them off nearly effortless. A thick platform adds more cushion and insulation underfoot while the outside channels water and slush away for better traction. The alpha cozy is the ideal everyday boot when the weather is anything but ideal.
