  • 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.

    We’ve shaved an entire line of footwear down to 10 oz. each, but kept the protection that made us famous. It’s addition by subtraction.

Care

KEEN water sandals are machine washable. Use a small amount of detergent, wash on gentle cycle and air dry.

We took our original hybrid sandal and gave it a lighter, lower-profile outsole and our new split-toe bumper for less bulk. Great for balancing on a SUP or wedging into a raft, yet it still has arch support, heel stability, and closed-toe protection for the trail.

• More Ground Feel: Our low-profile CNX outsole puts you closer to the ground for better balance and has flex grooves for natural movement.

• Made for Water: Quick-dry, washable webbing and mesh lining.

• 12-Point Fit: Quick-cinch bungee lacing for an instant secure fit, whether in whitewater or navigating a rocky trail.
