How to measure your foot length:
  • 1. Place a piece of paper against a wall.
  • 2. Stand on it with your heel against the wall.
  • 3. Mark where your longest toe ends (both feet).
  • 4. Measure from the edge of the paper to both marks in centimeters.
  • 5. Use the longest foot measurement and match it up to our size chart.

Technologies

  • KEEN.DRY
    A proprietary waterproof, breathable membrane that lets vapor out without letting water in.
  • 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.

Our bestselling waterproof boot for kids is ready for winter. We added 100g of insulation plus a thermal lining to keep not-so-little feet toasty in colder weather. Same easy on/off design and comfort kids love.
