This is a great playground shoe for my 4th grader. I love the unisex design. These shoes usually last 6 mo - until we need next size- but aren’t in same spotless shape that Keens are for passing down to next sibling. Still, they are far from bad shape after six months of abuse. Way better than UA or Nikes in our experience. I had adult version and had heavy rotation with other shoes, and still lasted 5 years before I gave to my growing son, and he trashed them in 6 mo wearing as lawn mowing shoes. As an adult, I add an arch support or metatarsal support insole. My kid hasn’t indicated it needs one for comfort - but it’s not as cushy at all compared to Saucony running shoes.

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.

… 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!
