These adidas Ultraboost 1.0 running shoes are perfect for all-day wear. The PRIMEKNIT upper hugs your foot and features a see-through cage with a faded print on the back. With BOOST cushioning, you'll feel energized and comfortable as you run, and the Stretchweb rubber outsole allows for a natural and efficient stride. This shoe's upper is made with a high-performance yarn, containing 50% Parley Ocean Plastic and 50% recycled polyester. The BOOST technology offers temperature-independent cushioning for ultimate comfort in any weather, while the new PRIMEKNIT knit fabric improves breathability in key sweat areas. The STRETCHWEB WITH CONTINENTAL rubber outsole provides excellent grip and moves in sync with BOOST for a smooth and flexible ride. Plus, the FIT COUNTER heel construction supports the Achilles tendon for maximum motion.
