This was an excellent track shoe for my nine year old son (not old enough or competitive enough for spikes yet like his big brother). He loves how light they are, the stability and the traction on the sole. He typically wears Nike but these outperform for young, recreational track feet. He says he feels like they allow him to run faster because they fit well with no slipping inside. They hold up very well too for the amount of use they have had.We had to get familiar with Adidas sizing. It seems that his usual size 2 Nike shoes are the equivalent of an Adidas 1 -- at least in the kid sized shoes. I was hesitant to rate them as running large, but I think that generally speaking their kid sizing convention is different as most of my son's other shoes are 2. We had tried on a bunch of other Adidas in store and found this to be the case. This style in his size wasn't available locally so we were really pleased to find them here on Amazon! My son says he would wear Adidas next year when track season comes around again!
