I don't know whether only my set was broken or if they all were - I hope the former! In any case, my Abbey has two right shoes! First I didn't think anything of it that both looked the same from underneath, but the second boot was extremely hard to put on and her big toe almost poked through the plastic in the end.
Since the set is not available in shops anymore I can't compare whether I was just unlucky. I guess so.

That's a pity since I bought the set mostly due to the ice skates. :(
