Cute and comfortable.
My son loves them. He's only worn them three times so I can't say yet how they hold up. But he's happy. My only wish is that the laces were a little longer so that he could have an easier time tying them. They do also come with an extra pair of turquoise laces.

saucony for life, kidz.
Color: Navy/Silver/Pink, Size: 7 Big Kid, Color: Navy/Silver/Pink, Size: 7 Big Kid
… why I appreciate being an adult female with average-sized feet, Especially considering kids’ shoes are always way cooler!
The sizing is a bit wonky, I’m normally a women’s 8, EU 39 which were my last saucony’s ,
These were exchanged after buying the “big kid 7” (too big),
after replacing w the 6.5 (38.5 EU) I still wondered about sizing down more but I think they’re good, they just fit differently than my previous ones… also I replaced the very long blue laces (48”) with shorter white ones (40”), and now I’m keeping and loving the shoes!

Runs Narrow
Color: Blue/White, Size: 1 Big Kid
They seem to run quite narrow, for my son who wears a medium comfortably. The New Balance fit much better.
