This casual, comfortable boot is ready for the weather, whatever it may be. Waterproof leather adds rainy-day protection, and a layer of light insulation keeps you cozy. A breathable lining keeps air flowing.

  • 100 grams KEEN.WARM insulation
  • Cleansport NXT™ for natural odor control

We've carefully selected leather uppers designed to last. Then again, if you're wearing your KEENs daily, they won't always be scuff and dirt-free. To treat day to day wear and tear, especially on lighter color leathers, we recommend using a leather cleaner and conditioner, found at most footwear dealers and/or shoe repair shops.
