A waterproof winter slip-on boot is one of those things you didn't know you needed until you have one. We made ours with cold-weather traction and extra warmth with a Thermal Heat Shield insole to trap heat and 200g of KEEN.WARM recycled P.E.T. insulation. Keep a pair by the door ready for dog walks, snow days in the city, après ski, and weekends at a cabin in the woods.

• Slip-On Convenience: Elastic gore makes it easy to get on and off.

• Winter Ready: Featuring 200 grams of KEEN.WARM recycled P.E.T. insulation rated to -25°F, a Thermal Heat Shield insole, and a KEEN.FREEZE outsole for cold-weather traction.

• Lighter Footprint: PFC-free water repellency plus environmentally preferred leather that reduces chemical and water use during the tanning process.
