I just purchased the AE Strand at the nordstrom sale, and have been wearing the shoes for the good part of today. I noticed as I was cleaning my shoes that they have small black smudges (I was able to wipe these off but it is still a bit dirty), the leather is very slightly cracking, and some of the stitching is fraying(slight but still a bit noticeable). I just finished exchanging a pair of shoes there and am hesistant to exchange ANOTHER pair of shoes...but I just have the feeling that these aren't living up to AE standard (the other pair i purchased are almost perfect condition). Has anyone had similar experiences? Are these imperfections common? Or do you think these flaws warrant an exchange?
