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!

Probably the perfect pair of kids shoes
Size: 1 Little Kid, Color: Black/Multi
No more lagging at the door on the way to school, my daughter steps right into these sneakers and is out the door in two seconds. The black base and rainbow elastic laces ensure they match any casual play outfit. And she has really emphasized how comfy they are and how they are so easy to put on and take off. My daughter runs and plays hard outside and they really take a beating! There are no breaks in the sole and no holes in the fabric despite the everyday abuse. I am very happy with these and would buy them again in the next size up when we are ready. The size fits as expected and my daughter’s foot runs narrow, but there was no gapping.

Perfect Every Day shoe for School!
Size: 12 Little Kid, Color: Black/Multi, Size: 12 Little Kid, Color: Black/Multi
My 5 year old daughter (6 next month!) picked these out for back to school. She started Kindergarten and she really liked these. They’re super adorable! Love the black since they’ll match pretty much any outfit. The rainbow is super vibrant and the fabric of the shoe is very soft. She says they’re very comfortable as well. She’s growing into a 12, so that’s what we went with and it’s perfect bc she had a little bit of room at the toe. They’re easy for her to put on and they’re very lightweight. The perfect every day shoe. She’s been wearing them to school for about a week and so far they still look brand new (that’s the pic I took from today.) Definitely recommend!

Great shoe for Littles
Size: 13 Little Kid, Color: Black/Multi
These were super comfortable for my 7 year old. They've held up and endured the play grounds and school days. Washed up easily, the color made that possible. These were super lightweight and didn't rub her heel when she walked.
