Nike Romaleos 4 sizing?

Wanting to buy a pair but they’ve been dropped from the Nike website so I’m limited in where I can buy them from / CS.

Those who have both romaleos 4 and Nike metcon 9s, are you the same size in both? Or different?

(Also has anyone heard if Nike is discontinuing their weightlifting shoes? Kind of odd that they’re all sold out and no replacement model).
