From the Manufacturer
Aura Performance is changing running and training shoes. For the same reason you no longer see wooden tennis racquets, straight skis or small wooden heads on golf clubs, Aura Performance’s technology will change the way you think about training. After ten years in development and thousands of miles of wear testing, they are proud to introduce the world’s first true footwear suspension system…Aura Dynamic Suspension System. DSS is a fully independent suspension system that is specifically engineered to better accommodate a runner’s size and weight. This unique technology also allows its springs to work independently, providing superior stability and more uniform displacement of impact--all allowing for an unsurpassed ride. Your performance will also improve due to measurable energy return capabilities in every step, as well as unparalleled cushioning and comfort. This high level of shock displacement will cut down on injuries and dramatically reduce recovery time between workouts. DSS…History will be made.
