Adidas have introduced the Springblade, taking their running shoe technology to the next level with sixteen individually tuned blades designed to propel runners forward. The forward-angle polymer blades have a special geometry that gives support while also offering a high energy return in any environment. In addition to this, each blade has been tuned to provide support during all phases of a runner's stride. When tested by the adidas Innovation Team, the shoe was said to be be seven times more temperature resistant than adidas models with a standard EVA midsole. Launch is due for 1 August with a retail price of $180 USD (approx. £115).
