Dunk SB sizing question vs Jordan for reference.

I’ve heard that because of the larger insole more padding and bigger tongue that SB dunks run a little bit tighter. I wear a size 12 in Jordans and I’m usually good because I have a narrow foot but I wear 12.5 and new balance and Brooks. From what I understand, they only make size 12 or 13 no half sizes in an sb dunk. Would it be recommended to just buy a 12 or a 13 for a better fit. Generally, speaking more room is more acceptable than being too tight we’re going up a whole sign seems a bit much. Any advice would be appreciated.
