They definitely run small. My daughter is a size 1 but after reading the reviews I decided on a size 2. They arrived and we tried them on straight away and they fit perfectly, she even said they were comfortable in them. Well fast forward to an event we needed them for and she hadn't worn them in over 30 minutes when she started complaining of pain in her heel and when we checked she had blisters on both heels ! We obviously can't return them as they are worn out but I would call it a waste of money as we only used them for a couple of hours.
