I unfortunately can't return them even if they did agree to take them back since I used an AMEX offer for $20 off of $100 from Adidas so I would lose that if I returned the pair. I'll just wear them and hope that they break in and get slightly less tight.
My first pair of 500s arrived and I went half a size up from my actual size and they fit pretty snug. My big toe is nearly at the tip of the shoe. I don't have wide feet or anything either. I'm normally a 9.5 but got a 10 like I do for 350s.
