Re-issued and rejuvenated in recent years, Adidas? Tubular silhouette started life as yet another of the brand?s high-performance running shoes. Unveiled in 1993, the Tubular allowed the wearer to alter the cushioning in the heel with a hand-held pump. Featuring a Vibrastop outsole and groundbreaking LCD display built into the insole, the futuristic silhouette introduced Adidas runners to the idea of customizing their running experience.
