Overview
The GEL-RESOLUTION® X tennis shoe creates advanced comfort for players who like to control the game from the baseline. The NIGHT ENERGY design reflects the nighttime dramas that occur on tennis' biggest stage. DYNALACING™ technology has been strategically designed to hold when extra support is needed. This allows you to experience a locked-in feel when you're making quick transitions. There's also a two-piece midsole design that helps improve stability when your foot lands on the court. 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. 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.
