AMAZING for my 7 year old daughter. She can tie shoes but I no longer have to wait on her to do so. It takes 2 seconds for her to put these on and she says that they are super comfortable. We have been to Silver dollar City multiple times and she never complains about her feet hurting! They are easily washed in the washer. They hold up great. I think they are very much worth the money! Fit normal.
