Definitely do not worry about that, the pinking isn't glued down anywhere on the shoe as far as I know. You could maybe trim it with some sharp scissors if you are extremely careful, but I would just let it ride and enjoy. Those shoes look amazing and I think you picked an outstanding style for a "first AE". Now just good luck keeping yourself from buy many more in the next few months, because after just a few wears you will be hooked. Cheers and welcome!
