Great for the price and the rhinestones add the extra pop.
Size: 2 Big Kid, Color: White/Rhinestones
My 7yo loves them. They appear well made and fit as expected. I saw some reviews of them being too big but no issues here. She’s worn them everyday for a week and she said they are comfortable. Color matches description and the rhinestones add the “extra sparkle” she loves. They did get some mud on them at recess but it was easy to clean off. Overall, no complaints for the price.

Inexpensively Cute, Resilient and Durable...
Size: 5 Big Kid, Color: Purple, Size: 5 Big Kid, Color: Purple
Purchased these cheap mesh-like breathable, high quality light-weight canvas material non-reputable, off-brand name sneakers for my stepdaughter because her puma sneakers were wet. My daughter loves them; not only are they her favorite color, she says they're very comfortable and easy to put on. They're easy to put on, with a slip on style and also have tie up for a tighter fit. My daughter also says likes the purple in-sole bubble that looks like a real air bubble but its really hard plastic volcanized to give a nice polished purple color finish. My daughter is happy with them, so I am too. They're well worth the practical cost, I look forward to them lasting a growth period of approximately six months to a year. Highly recommended. Pick you child's favorite color! You'll be happy you did...
