I think you'll be ok. I have a pair of derbies I was considering topying cuz of the quick wear I noticed on the heel but I never did. Turns out initially the wear is heavy but the crepe doesnt fall off in chunks too much, it just compresses, so after a certain amount of time you don't see as much wear progression as initially. Unless the crepe is substantially less dense on those (havn't had a chance to handle a pair myself :/) i wouldn't worry about it.
