This is the best sandal my kids have owned to date. My son who is 10, had a pair last year and they were great so I decided I would try some for my 1yr old little girl. I did order a size bigger than what she normally wears because the reviews said they ran small. I am so glad I did because I want her to be able to wear them in the summer and it is now February.  She wears a size 5 so I ordered a 6 and they are just a tiny bit big but still wearable. They will big perfect for summer. My advice, definitely order a size bigger. AND, they came within 2 days!!! Very happy costumer!!
