Stun your competition with your agility and speed on the court in the Jet Mach II. Built off the original Jet, you will step into comfort as the upper is made out of an updated Matryx 2.0 material which weaves together durable Kevlar and Plolymide threads to offer support and breathability. Active Flexxion technology continues to provide lightweight underfoot cushioning as the KRPS-X midsole absorbs harsh shocks engineered to be effective for tennis specific movements. With an outsole specific for clay courts, you will find awesome traction levels. Built to help you take your game to new heights, we found this to be a comfortably quick option for even the most aggressive movers.
