My kid loves these shoes. We’ve bought them multiple times. She can get them on and off easily and they stand up to her wild adventures.

So cute and so worth it!
Size: 3 Little Kid, Color: Turquoise
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.

Our everyday shoe!
Size: 13 Little Kid, Color: Turquoise
Great shoes and good fit. Fits as expected. The sole has worn down a bit quicker than I had hoped but my kiddo wears them everyday. I would buy them again for sure!
