Speed on the court is so much more than just sprinting quickly in a straight line. With the Wilson Kaos Swift 1.5 Clay, you'll be fast in all directions, whether you're moving from side to side or running back for a smash. Since lateral movement is crucial in tennis, this shoe is built on a Kaos chassis that provides you with flexibility and support for side sprints. We have enhanced ventilation to keep your feet comfortably cool at all times. Combined with the internal sock construction, this results in a shoe that is both comfortable and fast.
