Query: Heel Protector

My daughter is 10 and has Sever's disease. She doesn't weigh over 55 lbs and the extra small wouldn't fit on her foot at all. They should explain that it is hard to get on and possibly go by shoe-foot size instead of weight. Very disappointed. I had to reorder and pay more shipping to get new ones. Hopefully they work.
