Revel IV Mid Polar Boot

Thriving in conditions where snow can be thrown from a boiling pot of water requires a certain degree of preparedness and fortitude. And the Keen Revel IV Mid Boot readily steps in from the frozen tundra to embrace your feet like a favorite, hearth-warmed blanket with thermal resistance down to negative twenty-five degrees F. As you sip the morning brew on the cabin patio, the recycled PET insulation closes in around your ankle to trap in long-lasting warmth for sensitive toes. And as the day’s adventure gets underway on the snow-covered trails, the molded rubber outsole provides confident traction and resists the penetrating cold underfoot.

Keen achieve this astonishing level of protection from the inside out, starting with a Heat Trapolator footbed, blending insulating foam and felt with a shied that reflects heat upward to your feet, and adds a form of bumper guard on the heel and sides that resists cold transfer from the ground. On the exterior, a waterproof breathable membrane of leather and mesh protects the upper shoe from any water ingress as you break trails in deeper snow.
