More comfort, more performance Fastness on the court is so much more than just sprinting fast in a straight line. With the Kaos Swift 1.5 from Wilson, you'll be fast in all directions, whether you're running side to side or backwards for a smash. Because lateral movement is paramount in tennis, this shoe sits on a Kaos chassis that gives you flexibility and support for lateral sprints. Combined with the internal sock construction with an athletic (snug) fit, the result is a shoe that's as comfortable as it is fast. Highlights of the Wilson Kaos Swift 1.5 A flexible arch support for comfort and mobility and a lateral support for torsional control and increased overall stability. The full inner sock construction provides increased comfort, stability and an intuitive fit. The rubber overlay in the medial area provides additional durability and protection when pulling the foot. The high-density Ortho Lite foam offers maximum cushioning and impressive durability. Heel drop (9 mm) offers the best compromise between comfort and performance. The high-density, extremely hard-wearing rubber compound offers abrasion resistance and maximum traction on all surfaces. The midsole foam offers the best combination of cushioning and rebound for dynamic performance.
