Grand Slam champion Stanislas Wawrinka's shoe of choice, the Power Cushion Eclipse II offers exceptional cushioning, stability and support for the serious tennis player. Yonex's signature Power Cushion technology is newly upgraded with a 3-layer design that now absorbs shock more efficiently from harsh landings and transfers energy back up into the foot faster than ever for better court movement. The Guard Durable Skin upper helps the shoe keep its shape and provide stability when changing directions. The Endurance Rubber outsole has a modified herringbone pattern for great durability and traction on all surfaces. New Agility Bolt technology makes quick turns more possible than ever, with renewed construction that enlarges the size of the mid-sole part to the upper.
