Adidas Springblade Shoes
Shoes don’t really help you run as much as cushion your feet from repeated blows to the concrete – or at least not until now. The first shoe to feature sixteen individually tuned, highly elastic blades along the sole, Adidas’ Springblade releases energy collected with each step to contribute to the push-off. Or, in layman’s terms, it’s like running with springs under your feet. Springblade also features a flexible foot-hugging construction, is highly temperature resistant (presumably to prevent changes in bounce through various conditions), and, we assume, one spring density that fits-all.
