Constructed for comfort, the Tubular X Primeknit preserves elements from the original Three Stripes Tubular design of 1993, while adding innovative design features. Inspired by car tires, the original Tubular was the first inflatable shoe in adidas history. Dropped in June 2017, the 'Black Blue' edition is equipped with a high-top, breathable Primeknit upper with a textile lining. The Tubular X showcases a vintage white and gum midsole and Tubular outsole to keep the tradition.
