Rubs their foot
I purchased two pair of these for my 2 year old and 4 year old. They rub a blister on the inside part of their foot (where the circle rivet is). I had to put a band inside the shoe to keep it from rubbing, but it didn't help much. My 4 year old absolutely will not wear them now.
They are very cute, but I wish they didn't rub blisters their feet.
