Technologies

  • KEEN.WARM
    Our signature insulation is extremely compressible and light for the foot warmth it provides, and it retains its insulating ability, even when damp.

Care

Gently brush leather with a soft bristle brush or hand towel to remove loose dirt and debris. Tough stains may require a leather cleaner.

Whatever winter hiking looks like for you, warmth, comfort, protection, and traction are non-negotiable “must-haves.” So we built an insulated, waterproof, grippy hiker that checks all the boxes. All hike. No compromises.

• Warm and Dry:200g of KEEN.WARM insulation rated to -25°F and a KEEN.DRY waterproof, breathable membrane keep your feet toasty and dry.

• Better Leather: Environmentally preferred leather upper is lighter on the planet.

• Lightweight Cushioning: KEEN LuftCore technology embeds a lightweight foam core inside the midsole to absorb shock for comfort that lasts all day.
