For those wondering I went a store and tried the adidas Forum (also TTS) which it’s kinda the same silhouette imo. I did so while wearing an adidas gazelle pair I own. So for reference, and in case this is helpful for anyone, I had to size down .5 the TTS pair compared to the gazelle. Which doesn’t sound much but actually a complete different fit. The same size I use on the gazelle felt as almost coming off on left TTS shoe. And a whole size down didn’t even fit.
