Too bad because the foot wanders a bit width in the fangs. I would not say it's too long, the sizes are, nevertheless width that feet "floating" does not help the feeling of safety.
For children 4 to 6 years is "almost" pile it takes.
Should be able to choose the type of comfort you would like to buy based on feet of our children (or ours).
Overall buying without much hesitation because for 20 puncture-proof shoes for outdoor or beach this is perfect.
Character we all pair in the family including my own for 4 years and they have not moved ...
