Received these today and put them on right away for the gym. I have "normal" feet I guess, with rarely any fit issues. These fit just right. I wore them for a "boot camp" workout. Pistols, lunges, etc. were fine, felt stable, no slipping off or rubbing. Good traction. I haven't run in them but they feel good enough to do so comfortably. These would get 5 stars from me if they were as lightweight as my other, retired, shoes which were just about perfect (New Balance WE520 and W890).
