KEEN Focus Shoe: WK400

The Shoe: Following three years of development and more than 5000 miles of testing, Keen launched the WK400 walking shoe in February. Keen discovered that the foot moves in a constant arc when walking — a pattern that is uniquely different from a runner’s stride. To enhance this constant arc, Keen created its patent-pending Keen.Curve technology that combines constant curve geometry, underfoot plate technology and a high-energy midsole to create a feeling of forward momentum that makes walking feel like rolling. Additionally, a 30mm toe spring gives a smooth and easy transition from heel strike through to toe off. A 10mm last drop between the heel and forefoot further promotes forward momentum in the gait, while also aiding stability.

MSRP: $165

A Look Ahead: Keen is launching Waterproof and Leather versions of WK400 this fall.
