These are the shoes I wore at my wedding reception- Maybe 5 total hours of wear- and is the only time I have worn them. They are in perfect condition - sparkly and so lovely. The darker color appearance on the inside is from the adhesive padded cushion insert I wore on the wedding day- not from actual wear. It is not sticky, no residue - and shoes fit great! I love these shoes so much and hope they go to a good home!
