The HUGO BOSS X 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 extra stability and support from their shoe. 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 help 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).
