The Vibram FiveFingers KSO EVO is a versatile all around minimalist gym shoe and is part of Vibram's MAX-FEEL range. The KSO EVO is more than just an upgrade to the original KSO: it takes many of the best features from the other Vibram FiveFingers that are available and incorporates them into arguably the best offering for versatility to date. It has a zigzagging, sliced up Vibram rubber sole that provides excellent traction on a wide variety of surfaces. You will not find another shoe that is as good at manoeuvring on the spot. The Vibram FiveFinger KSO EVO includes the “max sole thickness" of 4.7mm with a 2mm EVA foam insole. The EVA foam compresses quickly, after which it moulds itself to the shape of the sole of the wearer’s foot, creating a more comfortable shoe. The shoe is made from a stretch nylon that is abrasion-resistant and has a breathable mesh upper.
