Light, comfy, and a brand you can trust with your feet
Size: 3.5 Big Kid, Color: Black/White
My son tears through shoes and somehow they're perpetually untied, no matter what we do. These are great as they don't need to be tied but look laced up, are very light and cushiony, and just look great so they go with everything. Saucony is also a great trusted brand that I've run a few marathons in myself, so I figured, let's try a pair and see how long they last. It's only been a few days but I'm getting good reviews from my son and they're his new go to pair.

Great shoe seems supportive

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
