We just bought these for my 3 year old ballet freshman year. After reading many reviews we increased her giant size from 9ft to 10B and she fit perfectly. If she keeps growing like a monster I don't know if they will last year round but full size increase was a good idea. The elastic tightens the extended parts so they fit perfectly and are easy to tuck into slippers. Can't comment on durability as dance class hasn't started yet but love the fit and the quality of the design.
