Our almost 2 yeard old used to wear crocs and while cute and comfortable....they would always fall off. We would see him walking with only one shoe almost all the time. We knew something had to be done. I am not a big advocate of keeping baby feet in socks and in shoes for a long period of time. Their little growing feet need air to breathe ! That's why I love these sandals. First, they are VERY sharp looking...much better looking in person. The pictures do not do them justice. Secondly, I agree with the other reviews...purchase the bigger size because they are very adjustable !  My son wears a size 7 and we got him the 8 and they fit just fine. Like the other reviewers mentioned...he will easily be able to grow into these because of the adjustable straps.  Best thing about these shows, unlike the crocs, they do not fall off ! What a God sent.  Super happy with these Teva's......we will for sure be purchasing these in bigger sizes as he gets bigger.
