The Vibram Fivefingers KSO EVO Womens is Barefoot Junkie's best selling barefoot trainer. The KSO EVO Womens Black has an ultra minimalist design to give the wearer a fantastic barefoot shoe experience. Built on a platform that offers the best ground feedback in the Vibram Fivefingers range, the KSO EVO Womens Black is part of the max feel Vibram product philosophy. The KSO EVO Womens Black shares the same 3mm rubber outsole as the Vibram Fivefingers EL-X for maximum articulation and ground feel. The outsole is made from the excellent Vibram XS Trek compound which is not only tough yet highly flexible but also Non-marking. The KSO EVO tread design offers great grip on smooth and rough surfaces. The upper features an easy to use adjustable speed lace system. This is what primarily distinguishes the KSO EVO from the EL-X which has a slip-on design. The breathable polyester mesh is reinforced with protective PU Film sections. There is a 2mm EVA insole with a Drylex sock liner. The Vibram Fivefingers KSO EVO Womens Black feel great on and this is typified by the superb sensory feedback you get from the tough yet flexible minimalist sole. They are lightweight and really allow your feet to flex and move more naturally giving your feet the freedom and movement they crave. As with all shoes in the Vibram Fivefingers range the KSO EVO have a zero heel to the drop to give a natural foot grounding.
