The Mizuno Running USA Sky Prime is in for testing!
And you can too. We’ll be hosting Riley Hennessy from Mizuno on October 3rd from our Denville store to demo the Sky Prime and other Mizuno models. One for a run, talk shoes, and maybe have an impromptu book club. More details to come soon.
The Sky Prime is Mizuno’s new premium cushion trainer. Built on a 47mm dual foam platform, the Prime brings surprising performance in a wide, stable package with a 6mm drop. The top layer of foam gets a new bouncy PEBA blend ENERZY NXT+ foam. The bottom layer gets standard ENERZY NXT, a supercritical EVA known for stability and impact protection (and a surprisingly fun ride, in my experience.) Up top is a comfort-focused plush upper with a stretchy knit tongue that holds the foot perfectly. Underneath, is Mizuno’s tough-as-nails X10 rubber.
It sounds like a recipe for success and first try on is shockingly comfortable. Full review with more miles!
