The SOLUTION SPEED™ FF 2 shoe from the NOVAK PACK celebrates the power of connection. Its colorway is inspired by individual yarns that are woven together in Serbia (Djokovic's homeland) to form a flat tapestry rug. The upper features a PU (polyurethane) application that helps generate better support, flexibility, and an improved fit. It also implements DYNAWRAP™ technology in the eyestay to provide better forefoot stability during side-to-side movements. TWISTRUSS™ technology in the outsole is functional for when you're moving from the baseline to the net. By allowing you to accelerate quicker, you're able to make faster cuts and transitions. This helps you get to the ball with more time to plan your shot with plenty of pace.
