IMO, you shouldn't be shoe polishing brand new shoes. Condition yes, but polish only sparingly. I would have applied conditioner to those captoes when new to see if it would be absorbed. It could have been leather shoes that were sitting on the shelves and they dried a little bit. I don't see any cracking.
I do condition before I do anything to a new shoe as a rule. The dalton was fine when I picked it up to replace the first one, but the toe was a little dull/matte, so I was looking for a little more pop. It's good after a strip of the polish and recondition. I was trying to avoid returning another boot I love, if I could... Appreciate the feedback!
