Equipped with the latest Max Air innovation, the Nike Air VaporMax Flyknit 2 Women's Running Shoe features up-to-date design details. The greater support on the heel combines perfectly with the wrap-around fit of the Flyknit. The silhouette is completed by a futuristic sole that makes the shoe perfect for a fast ride without giving up a sophisticated look. The latest innovation in the Max Air cushioning ensures an incredible fit from toe to heel. Eliminating the traditional midsole, the shoe is equipped with Nike Air units directly under the foot. The cushioning protects the foot from impacts during the race. And it ensures an exceptional fit. Elastic and plastic, Air VapoxMax ensures a feeling of absence of gravity. The extra outer layer on the heel offers more support than the previous version of the shoe. This ensures a more stable fit that prevents the swing of the foot during the run. Flyknit follows the natural shape of the foot for a comfortable and perfect fit like a second skin. The larger knit bill on the back of the foot ensures proper air circulation during daily 5K or for everyday activities. Further details: Flywire cables are integrated into the laces to ensure maximum support once connected; sole with rubber sections on the heel and forefoot for maximum strength.
