About this product
The GEL-RESOLUTION® X 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 GRX is fairly similar to the overall structure and fit of the GR9. The GRX fits a D width with a little extra room for slightly wider feet. If you are approaching a EE width, you will definitely want to go with the GRX Wide. The GRX is fairly similar to the fit of the GR9; however, with a higher medial collar for great roll-over prevention, the fit around the ankle is different.
