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.

My brand new Nat'l CXL had those same lines from the SF GMTO. It's not really an issue. However, donk's right boot is a bit more prominent than I've seen. It's really up to him if he wants to keep those or not - CXL is going to crease anyway. Suprisingly, mine have held up extremely well. Seems like I won CXL lottery.
