These flip flops are certainly very cute!  I read other reviews first and I would agree that they definitely run big.  My son is currently in size 4.5 shoes and the 3-4 size I purchased is still a little big.  I have to mention the backs slip off my sons heel, but I wouldn't call it a defect - I think my son has narrow feet/heels.  If you child has cute little chubby feet- I say they would be perfect!!!
