… 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!

They seem to run quite narrow, for my son who wears a medium comfortably. The New Balance fit much better.
