This is one amazing pair of shoes. I got this for my boys when they first started walking. This particular show goes up to size 6 however there are few more styles of the same (first walker) shoe that goes even higher in size. At first I was wondering why would first walker shoe goes so high in size but after I spoke to the company directly and the AAOP I learned that these shoes are not meant for first time walkers only but for later on as well. Now we have gone throug a total of 6 pairs (each kid) in the same style and we love them all. Super easy to put in and out and another thing to know is that the ther styles come in M, W and XW which is super important for little kids since their arch is different and this company make shoe shopping easy. Great quality as well.
