So my advice is to ignore the shoe size recommendation in the ad here. My daughter wears large size 2 girls shoes. (She is a small 12 year old). So I look at the chart and buy the average size listed for a size 2 shoe. The average ones were TEENY. For example for a 4 year old child if at all. Luckily I also bought the largest size available (says shoe size 6-9!), I figured she might wear them one day, there were only 4 left and I didn't want to miss them later. The large one, although a bit small, stretches well and works well for her. We returned small (medium) sizes without opening. At least Revain simplifies that part.
