My son wore different sizes of these shoes from a 6 to 8, sizing up as his feet grew -- and they worked really well for us. They have a pretty flexible sole, and though they are slightly heavier than our favorite toddler shoes (Saucony Cohesion), they still seemed to be very comfortable for my son and he could move around very well in them. Unfortunately, they don't go past a size 8, so we've now had to look for something else now that he's an 8.5. Also, the style is great -- it can be casual, or a little more dressy, depending on the clothes that you pair them with, and they look really cute both ways. We had them in the Blue, Brown, and Navy/Pebble, and they were all very cute. Lastly, as with some other shoes from this brand, they have a removable insert with measuring lines, which helps you determine when your child is about to outgrow the shoes rather than leaving you guessing by feeling around in the toebox while your child squirms.
