These are the cutest shoes. Every time I put them on my little boy we get so many compliments. They are also comfortable for him to wear, even in this Texas heat, and easy to walk in. My son is 16 months now, but we ordered the first pair when he was only just over a year old. I purchased the 18-24 month size because he does have some pretty large feet, typically wearing a size 5 in toddler shoes. I wanted to make sure he would have room to grow. And that was the perfect choice. They were a little too big on him a couple of months ago, but now they are the perfect fit. I just purchased another pair in a different color because I love them so much. He has worn the first pair several times, outdoors at the park and also at the beach, and I have not noticed any problems with excessive wear so far. I would highly recommend these for your toddler!
