My daughter just started running track and she really likes these; however, they run SO small. She is usually between a 1 and 2 in "big kids" sizes so we first tried the women's 2.5 based on reviews. They were laughably small so we tried the 3.5 and her toes were still scrunched at the front. We finally went for a 4.5 and those worked so definitely size way up!
