Anyone else? So many reviews have said it's equal to the performance of the Vaporfly(I'm looking at you, Believe in the Run) and for me it's not even close. I've taken them out on a couple of tempos/threshold sessions and beyond a significantly elevated HR to maintain paces that are much more efficient in the VF Next/Alphafly/Endorphin Pro, the feeling is that I have to work harder in them too because I'm getting less propulsion. Debating sending them back because there's no way I'd pick these in a race setting and they're $250.
