I purchased a size 10.5 M for my almost 5 year old daughter.  Like most little girls she wanted pink cleats.  I had to sacrifice color for quality in this case. (Thank God for Frozen and Elsa having a matching dress! lol)  These are excellent quality cleats and are super lightweight.  She wears these cleats comfortably and they don't rub her feet or ankles in anyway that might give her blisters.  Overall I would highly recommend these cleats!
