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.

My daughter is SUPER picky about shoes and loves these. They are easy and quick to put on, run true to size, and most important COMFORTABLE. She is outgrowing them and will have to get her the next size up. Highly recommend for picky kids
