There are a plethora of lightweight, speed-oriented performance shoes on the market, but not many can do what the Solution Speed FF 2 does! It remains light while still maintaining a high level of support, plus cushioning for the most aggressive movers. TheFlyteFoam midsole provides a smooth, plush ride while the Twisstruss system helps with stability for ultra-aggressive lateral cuts. One key improvement our testers found was the Flexion Fit upper material which contours to the foot better than before making movement seamless. Durability has been improved with added protection to the medial side for hard court sliders. The outsole provides a nice blend of grip, while not feeling overly sticky, catering to speedy players, like Alex de Minaur, who run down every ball on clay courts.
