  • 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.

When we walk, our foot travels in a constant arc, but our shoes are mostly flat. WK400 with KEEN.CURVE™ technology changes that. Designed for active walking, it’s our first shoe engineered from the ground up to create a unique rolling feeling and forward momentum. Whether you’re hiking the South West Coast Path, cruising up to a viewpoint with friends, or commuting by foot, the men's WK400 shoe makes walking more fun.

• Propels You Forward: Our patent-pending KEEN.CURVE™ Technology creates a feeling of forward momentum that makes walking more fun. If they feel a little different when standing, that’s because they were made for walking.

• How It Works: The WK400 balances plate technology, curve geometry, and last shape with a high-energy midsole to give you the feeling of forward momentum. It makes walking feel more like rolling.

• Field Tested: It took three years, nearly 10,000 hours of design and development, 5k miles of testing, too many cups of coffee, and a few tears to perfect the WK400.
