Too tight at opening
Size: 13 Little Kid, Color: Light Pink
I bought a size larger for my child, and the foot won’t go in. Her other sketchers slides are great. But I do not recommend this model.

It’s a perfect shoe without the correct width it needed to be wider
Size: 5 Big Kid, Color: Lavendar
The app suggested a 6.5 but I needed it in wide and it was not an option.
I had to send them back because they were too tight!
