The GEL-RESOLUTION® 9 WIDE 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.

RAY'S Fit/Feel assessment: The GR9 WIDE is fairly similar to the overall structure and fit of the GR8 WIDE.  The GR9 WIDE fits a EE width foot.  Forefoot comfort in the GR9 is an improvement over the GR8 due to a better design of the PGuard anti-abrasion coating.  Also, the forefoot cushioning seems more resilient and plush.  If you loved the the GR8 WIDE, you are going to really love the GR9 WIDE.
