I ordered a pair of shoes of the same brand in size 12/18 months for my son of 14 months. Unfortunately they were really great. So, I ordered a pair of 6/12 months that her perfectly. It is free to move as if he were barefoot, but her little feet are warm and above all it does not slip on the floor. Ideal for learning to walk. I keep the 12/18 months later. Proceeds received faster than expected, despite her from the United Kingdom.
