Great shoe seems supportive
Size: 3.5 Big Kid, Color: Black/White
Bought the shoe because it was recommended by a podiatrist for young kids and I'm pleased with what seems like good support.

Good fit. Good support. Good for my new runner!
The quality definitely meets our expectations. The price point is pretty good; I can't swallow adult-sized prices for kid-sized shoes. Delivery was early...which my son really appreciated!

Falling apart
Size: 5 Big Kid, Color: Teal/Periwinkle, Size: 5 Big Kid, Color: Teal/Periwinkle
I bought these two weeks ago for my daughter to train and use for a mini triathalon she is doing and the sole tread are already coming apart in several areas. Including the toe. Not worth the money

Not True “Running” Shoes
Size: 3 Big Kid, Color: Plum/White
Okay every day shoes but not great for running. I’m a small adult, who happens to fit in kid sized shoes. While it has its perks of being cheaper, finding a good supportive shoe in youth size has its challenges. Youth shoes are not always built to last due to the fact kids grow out of them quickly. I had high hopes for these, and bought them on sale. Initially trying them on, they felt great. But after a few runs and miles on them they just weren’t cut out for running. I only ever do a mile here and there. After a month and maybe only 10 miles in them I was experiencing shin splints. So they’re only good for every day errands and I upgraded my running shoes to something else. They do fit true to size though! Was to clean. And very pretty purple.
