Nice kids shoes
Size: 3.5 Big Kid, Color: Blue
I bought 2 pairs, one for my son and one for my daughter. they seem to run a tad snug so size up at least one size. My sons fit well right away, had to return and reorder my daughters pair, cause her size was too small, sized up twice and she now says they are super comfortable. They are proving to be fair sturdier than the other shoes I have bought them in the last year. The colors are true to the photos. I find them rather stylish, and my kids can easily get them on and off.. I've not had to clean them.

Must buy
Size: 2 Big Kid, Color: Blue
My 7yo loves doing his "magic trick" and stepping into his shoes. They slide on easy and stay on, they fit as expected. He says they are very comfortable and make him go very fast. Stylish as well
