The GEL-RESOLUTION X NIGHT ENERGY tennis shoe creates advanced comfort for the intermediate to competitive player who likes to control the game from the baseline and requires a stable, supportive shoe. The outsole is suited for Hardcourt surfaces. This colourway is rendered with a primarily black color palette that's offset with prism blue accents for contrast. 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. ​
