The Asics Gel-Resolution X(2E) men's tennis shoes create 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 extends into the heel for added stability during lateral movements. It's a functional feature that's effective when you are running covering both sides of the baseline.
