The Nike Women's Air Sunder Max 'Electric Green' celebrates the 25th anniversary of the retro training shoe. A neon green hue is executed on the zippered-shroud upper, featuring a black synthetic nubuck mudguard covered in reflective paneling. Opening the zipper reveals traditional lace closure and a tongue marked with '6453,' which spells out 'N-I-K-E' on the telephone keypad and represents the last four digits of Nike's global office number. Lightweight cushioning arrives via a full-length Phylon midsole with exposed Air-sole units in the forefoot and heel.
