The K-Swiss Ultra Natural is all-new for 2008 and is the lightest and most durable K-Swiss tennis shoe. Durability is achieved with an Aosta II rubber outsole and toe drag zone combined with a high-abrasion TecTuff toe wrap. Traction comes from a tennis specific, multi-surface wavebone tread pattern. Stability is maximized by an anatomically correct 30 degree radius midsole/outsole with large surface area and an external heel counter. Cushioning is achieved with a k-EVA 45 midsole compound, Shock Spring cushioned sockliner and a minimalistic microfiber upper.
