Spring shoes look goofy but adidas found a way to make them less so with the Springblade. Now less than a year since the Springblade was introduced, comes the new Springblade Razor. The 16 angled blades on each shoe are like springs to help you run or walk faster with less effort and more cushioning. It uses the same concept on the soles and with the same Techfit technology to enhance breathability and keep your feet snug as the original. But the new web design on the upper gives the Springblade Razor a more modern look compared to the standard mesh of its predecessor.
