Any ON Cloudrunner wearers here? (Read 128 times)

I just bought ON Cloudrunners today after being fitted at a local running store.  I'm not sure if I was hoodwinked into buying an expensive experiment or not.  Did a slow 3.5 mile run today with them (while trying a heart rate experiment at the same time) and my legs werre extremely fatigued. My right quad is killing me now.  I can bring them back within 2 weeks if I need, but thought I'd see if anyone had any experiences on here!
