Firstly, I would like to say that I have the adult versions of these, and I love them. They are great for warming up and wearing them to auditions/performances, etc. So we decided to get a pair for my sister, and we got the child sizes because the adult small was kind of big on me (I'm 5'2, 95 lbs) However, the large for kids, was too small. My sister (around the same height and weight as me) put them on and they were fine, they reached to right above the ankle, but when you stretch (splits, grand battements) they would be too small and feel like they would break. If she lifted her leg above 90 degrees, they would be very tight. So overall, I would recommend this to people who are under 4'10, or else probably get the adult sizes.
