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.

Gently brush with a soft, damp sponge to remove loose dirt. Treat stains right away with a gentle cleaner. Air dry away from heat.

Nothing helps kids outrun a snowball like being light on their feet and sure of their footing. Our ultra-light, ultra-warm waterproof snow boot has cold-weather grip and 400g of KEEN.WARM insulation rated to -40°F. The molded shell construction on bottom prevents slush from soaking in, while the cozy collar repels snow and cold rain without the use of harmful PFCs.
