|K-Swiss K-Ona S Shoes|
|AOSTA II RUBBER COMPOUND - High-density outsole provides unsurpassed durability from heel to toe|
|FLOW COOL SYSTEM - Enhances breathability and moisture management from heel-to-toe to keep feet cool and dry|

Racing shoes are ultra-lightweight, built on a curved last and stripped of the majority of cushioning and stability features found on most training shoes. Generally, the lighter the shoe, the more minimalist the design. You should choose these if you’re a fast, elite runner concerned predominantly with weight. Unless you’re very light, these aren’t for you if you run a marathon outside 2:45, or 1:30 for a half.
Since 1966 K-Swiss has represented innovation, quality, performance and style. Its signature K-Swiss 'Classic', the first leather tennis shoe, made its debut at Wimbledon in 1966 and more than 40 years later, is still a style staple both on and off the court. Today K-Swiss premium sports heritage has expanded from tennis footwear, to also lifestyle, running, training, nautical and free-running foot-wear that stands up to the performance demands of world-class athletes and trendsetters alike.
