Hoka Ora Primo Trainer in Black / Black. Hoka's cutting-edge Ora Primo design cues to deliver the boldest expression of their Ora franchise to-date. A futuristic silhouette that delivers the same post-run relief as its predecessor, the new Ora Primo has been elevated with a soft knit collar, elastic lace system and insulated puff upper for that seasonless, slip-on comfort you crave.
