Plenty of life left! Got it from a fellow hobby jogger for $130 shipped and I put 9 miles on them over the course of two runs. This is my third go at the Prime X series and I sadly think they just don’t work for me.

I loved the ride and every time I run in the PX series, my heart rate is lower and I feel super efficient hopping along in 50mm of stack. Hope someone else can get use out of them.
