The GEL-RESOLUTION 9 is a premium tennis shoe in our Protection+ Tennis range that is suitable for the player who typically controls the game from the baseline and requires a stable and supportive shoe with premium cushioning features. DYNAWALL support technology in the midsole now extends into the heel for added stability during lateral movements. It's a functional feature that's effective when you're covering both sides of the baseline.​ DYNAWRAP technology in the eyestay has been strategically redesigned to apply pressure when extra support is needed. This allows you to experience a locked-in feel when you're making quick transitions.​ The separated heel design helps produce a more stable landing for quicker recoveries in between shots. The outsole design is suited for all types of court surfaces (mainly hard courts).
