So my 2 year old son just started wearing KAFOs today because he is bowlegged. He wears a size 7 Toddler W shoe, but they are just barely accommodating the braces. He probably needs at least an XW or maybe even an XXW shoe. Also, I am trying to find some sort of sock that he can wear under the braces. I am looking for something thigh-high that could fold over the top and is not too thick.
