Basketball shoes are form fitting shoes, so the idea of "sizing down" in a basketball shoe doesn't make sense to me. Either you don't know your true size and/or you're accustomed to wearing one brand.
In my opinion and experience, Adidas is more true than Nike. I wear a lot of running shoes.
I think some people confuse their Nike sizing with their Adidas sizing. I usually go up 1/2 in Nike models, TTS Adidas. They're snug, but that's how basketball shoes should be, maybe go up if you're wearing them casually.
Finally got my pair, came with an ugly crease on one of the shoes, but I’m keeping them. I can tell they’re going to feel great once broken in. They definitely fit tts.
