Crocs Baya vs Orignal Shrink help!

So I got the original pair and they have shrunk over time but are still oversized but good for me.

I got the baya ones today and I got an exact size plus a size up.

Both are smaller somehow than the originals and I’m worried they may shrink or may not.

The exact size is considerably smaller than the originals but an exact size to what I want (if they don’t shrink they would be awesome), but the size up is slightly bigger but not the size of the originals somehow as those are still bigger.

What to do.
