Karhu's classic Fusion 2.0 runner arrives with a seasonal colourway and layered uppers, ranging from mesh, leather and synthetics. Branding adorns the sidewalls and tongue, while speckled hiking-inspired laces lock you in up top. The sole unit is equipped with Fulcrum technology too: this is a pivot point in the midfoot that propels you forward, while providing cushioning and energy return for a premium, cloud-like feel.
