My little guy is almost a year and has had chunky feet since he was a couple of months old. They aren't necessarily fat, just solid and thick in the middle. It has been impossible to find him sandals that fit him. We've tried every flip flop and water type shoe out there. These Teva sandals have solved our problem though! Since both straps are adjustable (unlike every other shoe out there that only allows you to adjust the ankle strap) they fit his chunky feet PERFECTLY! We bought the camouflage/dark olive sandals for him and the colors are great and go with most of everything he owns. I love these and will end up buying more once he outgrows these since I don't think he will outgrow his chunky feet anytime soon.
