The K-Swiss Men's Defier boasts superb all round performance. Defy your opponent's best shots with the complete combination of comfort, support, durability and response. The stellar levels of durability in this shoe are afforded by the Aosta 7.0 high density rubber outsole, DragGuard abrasion resistant material placed in the hard wearing toe and heel of the outsole and moulded Dura-Wrap protection around the toe and on the medial side. Traction comes courtesy of the tennis specific herring bone tread pattern, suitable for multiple court surfaces. The tread itself wraps around the toe and sidewalls for added grip in these crucial areas of the shoe. Support is so crucial to success on the court and the Defier won't leave you wanting with an external TPU heel chassis and an extra high lateral sidewall at the forefoot. Comfort is enhanced with vented medial cut-outs and an open mesh tongue that allows for a greater degree of breathability keeping you cool and calm on court.
