Bought these for my seven year old after he tore through a cheaper pair of tennis shoes in a month. These have held up very well, still looking decent after several months of heavy use, just a few minor scuffs. The fit is great and they are very comfortable for him. My only complaint is that they are not as breathable as I would expect and my son’s feet get hot and sweaty very easily inside. Overall, they’ve been very durable and I would buy again.

Favorite shoe for my picky kid

Size: 3.5 Big Kid, Color: Navy/Red

My picky child loved these. Worn a hole in them because he lived in them even when his feet grew and didn’t want to give them up. Finally convinced him to give them up. Now looking for his next favorite shoe. These were not Merrill brand like the name states. These were Saucony Kinvara.
