If you wear the boots for a week then there'll be sufficient creases on the uppers that you won't be able to pick out the mark. Provided the boots themselves aren't damaged, it shouldn't matter.
That said, even if Viberg are selling work boots, they're charging a significant amount of money for them. It's not an unreasonable expectation that they'll arrive unmarked. Either it's a problem with manufacturing and QA, or they aren't packed well enough for shipping.
