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.

Fantastic, stylish, and easy shoes!
Size: 2.5 Little Kid, Color: Aqua/Multi
My daughter LOVES these and wears them daily. She says they're really comfy and they slip on easily. They've held up for several months of daily wear so far and are still going strong!

Awesome shoes!
Size: 4 Big Kid, Color: Aqua/Multi
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
