Best Toddler Sneakers
Started using them when my toddler was 1.5 years old (she wore the size 18-24). Since Robeez doesn’t have bigger sizes of this shoe in their website and they also don’t deliver to my country, I looked in Amazon and to my surprise I found them. So I now have the next size. My toddler loves them, they’re comfortable, easy to put on/take off and beautiful. I highly recommend all Robeez shoes (if they deliver to your country!)

Double check sizing
Too big for my toddler, recommend sizing down. Quality is good if the fit is good.
