Our Take 

The GEL-RESOLUTION™ X tennis shoe creates advanced comfort for players who like to control the game from the baseline.

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.

Lastly, the higher medial collar helps increase support for either a more flexible foot or the player that is more aggressive in their movements.
