The GEL-RESOLUTION 9 X HUGO BOSS tennis shoe creates advanced stability and cushioning for players who like to control the game from the baseline.  DYNAWALL 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 running 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. Lastly, the full-length outsole and separated heel help produce a more stable landing for quicker recoveries in between shots.
