GEL-RESOLUTION X | Men | White/Black | Tennis Shoes | ASICS 。Men’s 12.5 nwt. 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 comfort and 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 adds extra support when making abrupt cuts back and forth.
