Okay, so as promised. My pair of EQT Support ADV in the OG/green colorway arrived and i finally got to inspect them and try them on (GORGEOUS shoes by the way/ the shape is what the NMD should have been).
DO NOT, i repeat DO NOT size down a full size. Contrary to someone's comment in this thread about them being Prime Knit and running big thus requiring for them to be sized down, both piece of advice are INCORRECT.
My feet are considered to be narrow to normal width and sizing down .5 from my TTS, would still be too snug (and this coming from someone who likes his shoes snug).
With all that said, these run TTS so i would highly recommend going with the size you are in your UB, i would imagine that wide footed folks might want to consider going up a .5 size since this model' toe box is very tapered/slim.
