With mid-high kicktail and mellow concave, Surestance Pro Fusion may just be the Goldilocks of the Surestance Pro family. Fusion offers a different profile than Surestance Pro, with its concavity starting from the center of the pad resulting in a more gradual lift from heel to toe. The net effect is a comfortable and supportive ride feel that still provides substancial kicktail for foot reference and control.
