The KEEN Revel IV High Polar is a men's winter boot built for deep cold and deep snow. It pairs a waterproof leather and mesh upper with 400g of recycled KEEN.WARM insulation rated to -40°F, plus a three-layer Heat Trapolator underfoot and a thermal insole. The high profile and KEEN.POLAR TRACTION outsole with 5mm lugs target powder and ice. Against lighter winter hikers it trades bulk for warmth and grip; owners rate it highly for exactly that.

The KEEN Revel IV High Polar is a waterproof men's winter boot with a higher profile for deeper powder. It has 400g of KEEN.WARM Recycled P.E.T. insulation rated to -40°F/-40°C. The upper is waterproof leather and performance mesh, with a breathable textile lining.
Heat Trapolator technology uses three layers of heat-trapping materials underfoot, and the Thermal Heat Shield insole captures warmth. The Original Fit has generous space across the forefoot so toes can splay. A notch in the back allows Achilles movement.
The KEEN.POLAR TRACTION outsole is made for better grip on snow and ice. It has 5mm multi-directional lugs. A compression-molded foam midsole provides cushioning, and a stability shank adds lightweight stability. Metal eyelets add durability.
