The GEL-RESOLUTION™ tennis shoe 9 of the NOVAK Pack is inspired by the idea of being there for each other and living giving your best. ???DYNAWALL™ technology in the midsole now extends to the heel to offer greater stability in lateral movements, an important feature when running to cover both sides of the baseline. DYNAWRAP™ technology in the reinforcement eyelet has been strategically redesigned to apply pressure when extra support is required. This way, you can experience a more stable sensation when making quick transitions. Finally, the full-length outsole and separate heel counter help provide a more stable foothold for quick recovery between shots.
