For the rally that won't relent and the marathon match that must end in your favour, go with the Vapor Pro 2. We brought back all of the elements you enjoyed in the original Pro: the low-to-the ground design, the springy Zoom Air that helps you break from baseline to baseline and that familiar Vapor comfort that helps keep you fresh on unforgiving surfaces. We coupled those improvements with our innovative Claybreaker technology to help keep you quick on the court.
