KEEN WK400 Men – Walk Further with Less Effort

KEEN WK400 Men is an innovative walking shoe designed for people who spend long hours on their feet. Whether you're exploring a city, travelling, commuting or simply enjoying long daily walks, the WK400 delivers outstanding comfort and a unique walking experience.

The shoe is built around the revolutionary KEEN.CURVE™ technology, featuring a continuously curved sole geometry that naturally rolls your foot forward. This design promotes smoother transitions, improves walking efficiency and helps reduce fatigue during long distances.

KEEN.CURVE™ Technology

The patented KEEN.CURVE™ system combines a curved rocker sole with a full-length nylon propulsion plate to create a dynamic rolling motion. Every step feels smoother and more natural, making walking easier and more efficient.

All-Day Comfort

The lightweight performance mesh upper provides excellent breathability while TPU overlays improve durability and structure. The padded tongue and collar increase comfort, while the offset lacing system reduces pressure across the top of the foot.

A removable resilient foam insole and high-energy midsole cushioning provide excellent shock absorption throughout the day.

Grip and Stability

The durable rubber outsole features a multidirectional tread pattern that delivers confident grip on pavements, parks and light trails. A full-length nylon plate improves stability while supporting the KEEN.CURVE™ rolling geometry.
