The instructions state to order 2 sizes larger than street shoe. My daughter wears an 11.5 to a 12 in a street shoe so I ordered a 13,5 making the ballet slipper 1.5 to 2 sized larger than her street shoe. The slippers came and are at least an inch and a half too long! I cannot comment with confidence on durability, but they seem VERY thin! Now I have to order another pair and hope she likes them enough to wear them when she grows in the 13.5's in a year or TWO!
These are really good shoes, they flatter the feet really nice. But it didn't seem like it had a lot of padding on the instep. Also the shoes got really dirty looking really fast. But over all the shoe is comfortable and looked nice on my feet.
These are good quality canvas shoes for my youngest child. They gap a little when she is on releve, but they wash up nicely in the washing machine and children grow out of them so quickly, you can't beat the price tag.
