Just to add to the sizing talk. Got my 11.5 Bariums in today and they fit pretty well but a little snug. I'll post a list of what I wear in other yeezys but in my opinion they fit like an 11.5 clear stripe 350 v2. Not sure if I'll hoop in em yet, but if I were to I'd probably prefer a 12 (what I wear in all my kobes/hoop shoes) so that toes aren't completely jammed up when I'm playing. I'll stuff the toes with some paper and see if it loosens up the top because they're pressing down on the top of my big toes right now. If I had the choice, I would go with a 12 to hoop in and 11.5 for casual wear so I wouldn't have to tie them up super tight walking around.
For sizing reference:
350 v2 no stripe: 12
350 v2 clear stripe: 12
500: 12
700 v1: 12
700 v2: 11.5
kobes and all hoop shoes: 12
Also for those that have them, does anyone else feel like the tongue should've been a little longer? If you want to go through the last lace loop and tie them, you basically are tying the knot on your leg because the tongue doesn't cover that high
