These are very good quality and are very durable.
My son is 3.5yrs old and just started to wear a Little Kid size 12 shoes. He has a regular width foot. I ordered a Little Kid size 13 Keens to be sure that they would fit and they fit him great. I'm however crossing fingers that they will fit him for next year that was the whole point of ordering up a full size. I recommend ordering up one full size if you want your child to fit in them for the following year if not order a half size bigger. My son wears DC shoes, Adidas shoes, Vans shoes, Converse shoes and Airwalks the fit has always been true to size but Keens seem to run a half size small. I hope this as well as the brands that I mentioned help give you an idea on what size to get for your child.
