This week, Keen launched a new walking shoe called the WK400. The $165 style is designed with patent-pending KEEN.CURVE  technology. According to the brand, the design combines constant curve geometry, underfoot plate technology, and a high-energy midsole to create a unique feeling of forward momentum that makes walking “feel like rolling.” The WK400 also has a 30mm toe spring that delivers an easy transition from heel strike through to toe off. A 10mm last drop between the heel and forefoot further promotes forward momentum.

The idea for the shoe evolved from a traumatic experience. Four years ago, Keen's Global Product Innovation Creative Director, Rory Fuerst Jr., suffered a skiing accident that left him unable to walk for several months. Along his road to recovery, he says that discovering the simple joy of walking helped bring him out of fog and depression and saved his life. The experience served as a catalyst for the brand’s new walking technology and shoe.

The WK400 is available in four colors across men's- and women's-specific fits. It is available online and at select retailers now.
