As a kid I always thought I could run faster and jump higher when I got a new pair of shoes. I am sure 99% of that magic feeling was just in my head, the good old fashioned placebo effect.
The Adidas Springblade ($180) might actually make you run faster, this time for real. Adidas has added "blades" that are tilted backwards and are supposed to propel the runner forward. Assuming they come in other colors I might try them out when they are released (August 1st)
Unlike standard EVA midsoles that deliver energy return in a vertical direction, Springblade features 16 forward angled blades made out of a high-tech polymer. The highly elastic blades instantaneously react to any environment, compressing and releasing energy to create an efficient push-off that feels like you have springs under your feet. Each blade is precisely tuned in geometry, thickness and position for each phase of a runner’s stride to provide support and a full range of movement. Additionally, Springblade’s flexible construction was designed to hug the top of a runner’s foot, locking it in to harness the energy returned from the springs on the outsole.
