The Karhu Fusion 2.0 is a tribute to the original 1996 model, once the flagship shoe of the Karhu collection. In collaboration with the original designer, Karhu has reinterpreted the Fusion to bring back this iconic design in a modern sneaker: the Fusion 2.0. New to the Fusion 2.0? We recommend ordering half a size up from your regular size. Made with rubber material.
