Our son is just over a year old and is now on his second pair of these Pediped.  Other reviewers have said they run a bit small, and I would tend to agree with that.  Our son is in the 75% height and weight and these have a little bit of room for him, but not as much as one might think.  Initially they kept slipping off of his feet, but then my wife took out the insert and they now fit his feet perfectly and do not slip anymore.  They are stylish and look great and the tread on the bottom with rubber soles appears to be very durable.  These are the first shoes he will have where he is really walking on his own so it will be interesting to see how they hold up, but he appears to be very comfortable and they fit great-but only after removing that insole.
