Hello ladies. Literally just received my first Gucci shoes today and I'm a bit disappointed since one of the shoes has a yellow crusty stain on the inside (I think it could be glue but I'm not sure). I am assuming this is not a normal occurrence and that I should return but was wondering if this has happened to more people? I thought Gucci shoes were supposed to have excellent quality so this definitely came as a surprise! What are your thoughts?
