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.
