Big Kids' Kootenay Waterproof Boot

$75.00

Please choose a size!

Cozy faux shearling lines this warm, waterproof boot, made of a tough leather-and-mesh mix. Waterproofing seals out the elements, while a snow- and ice-gripping sole adds all-terrain traction.

  • Hook and loop strap over instep
  • Waterproof breathable membrane

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.
