The improved KEEN WK400 X2 women's trekking and sports shoes bring a provocative approach to walking. Rounded sole with KEEN technology. CURVE creates a constant sense of forward movement. What may seem strange while standing around, you will understand immediately as soon as you step forward. It's like you're rocking in the WK400 X2. The upper is made of solid mesh, which has reinforced overlays for higher durability. The mesh lining is breathable, ventilates well and the environmentally friendly Eco Anti-Odor technology ensures natural odor control without pesticides. Comfortable wearing is contributed by lacing off the axis of the instep, softened tongue and collar of the shoe, as well as soft foam padding. Contoured Fit supports the foot with a snug fit and comfortably wraps around the foot. A full-length nylon plate gives your stride more stability. Rubber outsole with multi-directional pattern ensures stability and traction on a variety of surfaces. Shoe maintenance: Clean with a soft brush and a cloth soaked in lukewarm water. Dry slowly, never on a direct heat source. Do not wash closed shoes in the washing machine.
