I need help!! My DD's skates are too small as they are about four years old. She only likes Riedell's as that is all she has ever known, Her old skates were model 91. Does anyone know if the current model is 910? also her coach recommends something for double jumps and there are so many to choose from. I am looking to get used or new but at a good price. My DD has started back skating after a long break and I don't know how long she will continue to skate as she is cheering for her high school, so obviously I'm not looking to spend lots of money on these!!
