I bought them for my 4-year old for a 2-week dance camp - not for heavy use. The first pair was too small (I ordered half size up from her usual, but they didn't fit at all). On the plus side, I was not charged for the return and the new pair in size 10 arrived quickly. When unpacking them I saw that the box looked different from the first one and they had some small issues (a bit of glue visible on the trim of one, slight discoloration around the ties of the other). But these were just cosmetic and I was running out of time for a second return so I sent her to class with them. Today is only the 5th day of use and the inside of the sole is coming off! It's probably a glue problem again, but it literally is tearing in several places, so we'll have to glue it ourselves if we want these shoes to hold for another week of camp.
I was very disappointed - sizing issue was almost expected based on reviews, but few people seem to have had such quality issues. I am starting to wonder whether we got a refurbished pair or something.
