The Zoom Fly SP is specifically designed to enhance long-distance running performance. It comes equipped with a Lunarlon cushioning system and a full-length infused carbon midsole plate, which work together to provide optimal comfort and support. The translucent upper in Guava Ice color not only adds a trendy touch but also allows for airflow and flexibility, keeping your feet cool and unrestricted during your runs. As a tribute to Nike's ambitious Breaking2 project aimed at surpassing the two-hour marathon mark, the Zoom Fly SP boasts special detailing that pays homage to this remarkable feat.
