Get back what you put in. Our new nylon Speedboard® makes for powerful forward rolls and shaved-off seconds. And a Helion™ superfoam midsole softens landings and springs you forward. Prepare to leave limits in the dust. Results of an independent study conducted with Progressive Sports Technologies based at Loughborough University showed that the double CloudTec® reduces both the onset and duration of muscle soreness. So you can just keep going, and going.
