I was a die hard kinvara fan until the 10s. The change from everun to Powerun just didn’t work for me. They felt hard. I was lucky to find another pair of 9s before the endorphins were introduced. This show feels a tad heavier but the cushion is awesome. The pro reviews about stability at slower speeds are spot on. But I still wear these for everyday and tempo runs. There is also definitely less of a ground feel with the 8mm drop, coming from the kinvaras but I’m happy with my purchase and am considering the shifts to replace my kinvaras as well.
