The LOOK of SPEED In a fluid design that expresses the speech of speed, the Nike Air Zoom Winflo 6 shoe has less footprint and a more sculpted profile than previous versions. Instead of a single Zoom Air unit, it has 2 for targeted responsiveness in the forefoot and heel. At the top, a engineered mesh optimises breathability. 2 Zoom Air units give a feeling of responsiveness and stability under the foot. The engineered mesh upper provides support structure and breathability. The elegant and carved profile creates a snap look. Partial shoe wraps around the foot for a comfortable and secure fit. The foam in the heel does not compress the Achilles tendon and provides ideal comfort. The lightweight Cushlon foam provides soft and elastic cushioning of the midsole. Waffle elongated flaps reduce the time of the foot to the ground. The rubber crash rail on the side sole provides maximum cushioning, while a crash pad improves resistance in the area most prone to wear. Triangular cutout reveals a Zoom Air unit inside.
