” The Nike Lunar Ballistec in a men’s size 10 weighs just 13 ounces with the introduction of Nike Lunarlon, a proprietary Nike technology that provides extra cushioning while keeping the shoe lightweight and responsive. That weight reduction translates into pure speed to the ball for tennis athletes.
Nike Tennis continuously focuses on delivering lighter, faster and better products for tennis athletes. That journey has trade-offs and challenges—especially with regard to footwear. A light shoe needs to be durable enough to last five sets on hot, hard courts or slide with finesse and control on clay. But a shoe with the right protection and support elements needs to be faster than its predecessors. ” – Nike
