This durable, comfortable hiking boot will take you anywhere, whatever the weather. Two types of insulation cut the chill, and the outsole is designed to holds its ground in icy, slick conditions.
Keen Dry - A proprietary waterproof, breathable membrane that lets vapor out without letting water in.
Heat Trapolator - Three layers of innovative heat-trapping materials get sandwiched underfoot to hold warm air in. Works a lot like the insulation in your house.
Thermal Heat Shield Footbed - On the outside, wooly softness; in the middle, support cushioning; and inside, a thermal foil barrier to harness radiant heat. Keeps the cold out and the heat in.
