… 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.

Comfortable boy shoes

Size: 4 Wide Big Kid, Color: Black/White

My son’s favorite sneakers. I think this is a fourth pair we ordered as he grows. Lightweight but mostly wide enough to be comfortable. I wouldn’t buy them for a full price but they are often in sale and then it’s great value for my money.
