I just bought my first pair of TB reva flats in the chocolate snake print. I must say that I LOVE them, but they feel a bit big (my heel can come out occasionally)... but the logo medallion in the front is killing my left foot below my big toe! I really want to keep these shoes and really really want to wear them often... any suggestions? I don't want to go up a size as these are a tad bit big already... can you stretch the snake print one? I don't want to ruin the faux scales!?!
