The METASPEED Edge 2 racing shoe is designed for stride or cadence-style runners who are looking to start fast and finish faster. The main difference between both shoes are the carbon plate positioning and shape. The METASPEED Edge 2 shoe features a new toe-spring shape that raises the heel lift to propel you forward. Its design also has approx. 130% more FF BLAST Turbo cushioning than the previous version. This helps produce a more responsive bounceback in every step.
