These are the only qasa's that I actually got tts, if I remember correctly I took the chance because they didn't have a half size smaller. Surprisingly, they worked out though. Idk if being a high and my wide feet but they are not sloppy or anything(that funky toebox creasing from extra space). I've worn them a few times already and no issues.
I will say though that they are roomy and if I would ever cop again I would definitely try for the half size down for a snugger fit. I have only gone down a half size in my other qasa's(lows and racer) because I feel my feet are too wide to go a full size down, BUT if I had skinnier feet I would have gone down a full size.
