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, which is highly insulating, has antimicrobial properties, and offers a great warmth-to-weight ratio.

The Thermal Heat Shield insole features a soft woolly exterior, supportive cushioning in the middle, and a layer of thermal foil 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 odor without heavy metals or harmful chemicals.
