An evolution of the Trigenic Flex, the Evo delivers casual style with a crafted sports look. Staying true to the pioneering icon, this modern silhouette uses an asymmetric last and three-part, decoupled Vibram® sole unit. Crafted with feet in mind, the outsole features a linear map of the human gait cycle emphasising the high stress areas of the foot, while elastic on the upper is used to reflect the muscle tendons.
