I recently purchased these as I've been a fan of the KSO EVO and it seems like the Alpha has a very similar construction. I've taken them on 5 treadmill runs and 5 road runs and they fit and feel really great. They're very light too, just like the KSO EVO. The big difference between the 2 models is the new Megagrip sole on the Alpha which I think are going to handle great on trails and going off road. It feels like there's a little more protection with the Alpha sole than the KSO EVO sole. I don't feel the ground as much as I do in the KSO EVO but it still has that minimal barefoot feel that I love. Seems like an all around great shoe! Very happy with it!
