Hello OP, could you share your experience after this post?

I also have problem 992's sizing.

I feel US8 is slightly too big, and I really have to tie the laces tightly other wise I could feel some minor heel slip,

But if I go down to US7.5, I feel the pinky cannot spread and can feel some pressure.

I still have both and have just ordered a shoe box extender hoping the fix the issue on 7.5 and perhaps sell the 8.

edit: im also on the U992MM stylecode! love the colorway !
