Tennis players who prefer to control the game from the baseline will benefit from the increased stability and cushioning that the Gel-Resolution 9 tennis shoe provides. The midsole's Dynawall technology is now extended into the heel for more stability when moving laterally. It's a practical feature that works well when you're jogging along the baseline on both sides. The eye stay's Dynawrap technology has been carefully engineered to strategically deliver pressure when more support is required. As a result, when you're making quick transitions, you'll feel locked-in. The split heel and full-length outsole also contribute to a more secure landing, which speeds up recovery time between shots.
