And I know that too but I would like to continue this conversation in an appropriate place if there is such a thing. The topic of authenticators who authenticate a single (or small number) of labels vs. those who authenticate by understanding and being able to differentiate problems of construction is obviously near and dear to me and I don't consider one better than the other regardless of whether authentication is free or charged but from the comments posted it seems that you guys do and when it comes to a paid service an authenticator is best label specific. That's all I'm disagreeing with. I don't think you have to be expert on a specific label to give an expert opinion on designer footwear authenticity if you're expert on how footwear is made but you do need to be expert on how fine footwear should be made.
