Nike Free Trainer 7.0 has seen a number of alluring iterations since its debut in 2004, from the initial model to the weather-ready Shield edition and now a new rendition that incorporates Nike’s advanced technologies. The Free Trainer 7.0 NRG features a predominantly black upper with vibrant blue and yellow accenting at its tongue, lining and “Dynamic Flywire” eyelets. Elsewhere the gradient furthers onto the inverted Swoosh at its lateral heel, while the perforated toe box allows extra breathability. Sitting atop a white Free Run midsole and a serrate yellow outsole, the dynamic profile is fitting for a number of outdoor training activities, adding a boost of style to your workout. The Nike Free Trainer 7.0 NRG is now available from the Nike online store at $120 USD.
