where the foot enters into the shoe, ankle area so small so tight that 2yrs old fit toddlers feet can't go in to size 7. These made for toddlers with skinny and very narrow feet. good looking boots, but sole is too hard no flex to it. the ankle (neck of the shoe) portion has no stretch at all, nothing is stretching or flexing to get regular feet in there. your toddler must have very narrow and skinny feet to fit in. they also looks like run half size small.Otherwise they are great looking, soft inside, cushiony sides and rugged looking boots with thick fleece.
