I bought these for my narrow footed 6 year old.  If I tighten them across the foot it leaves to much length on the buckle end and I can't tighten them enough around his ankle.  The leftover tab is also super long and drags on the ground.  I tucked it into the loop on the back but that makes it a pain to take them off.  These were recommended by our doctor for a flat foot issue and I think they would be great for someone with a wider foot and thicker ankles.
