The Keen WK400 Walking Men's Sneakers are ideal for travel and everyday wear. They have a contoured cut that follows the shape of the foot, and the KEEN.CURVE provides a smooth transition from toe to heel. The green color goes well with travel outfits. The directional tread on the KEEN.ALL-TERRAIN outsole ensures grip on a variety of surfaces, while the nylon reinforcement increases stability. A removable insole and flexible foam improve comfort during all-day activities.
