My ds is 2.5 and is starting to grow out of his size 11 shoes!
The last time I took him to get shoes a couple of months ago the girl measured his foot and said he is no longer in toddler sizes! I knew he had big feet but I didn't realize how big until this thread! He is also very tall for his age so I guess its all in proportion!
His very first pair of shoes were a 6.5.
