Keen Revel IV Mid Polar

This robust, comfortable hiking shoe will take you anywhere in any weather. Two types of insulation keep you warm, and the outsole is designed to provide traction in slippery conditions.

KEEN.DRY is a waterproof, breathable membrane that wicks moisture away from the inside while preventing water from entering from the outside. KEEN.WARM is a lightweight insulation made from hollow polyester fibers and heat-retaining bamboo charcoal, offering high insulation, antimicrobial properties, and an excellent warmth-to-weight ratio.

The Thermal Heat Shield footbed features soft woolly cushioning on the outside, supportive padding in the middle, and a layer of thermal film inside that harnesses radiant heat. It keeps the cold out and the warmth in the shoe.

ECO Odor Control: The insoles are infused with probiotic technology that naturally breaks down sweat odors without heavy metals or harmful chemicals.
