I preordered my size (only pair in my size) and when they arrived to R&H they were shipped straight to me so I do not believe that to be the case. They are approx 1" indents in the leather and not creases.
I've seen some pairs on IG with similar marks. Found this with a quick #viberg search, left boot, pretty much same mark and positioning. Very different than the creasing actually on the roght boot.
