well toddler sizes and 'kids' sizes kinda confuse me, but I can tell you the measurement of the insole and hopefully that will help better. From toe to heel, the insole measures 7"
There is no big kid size 12 so I'm not sure about the confusion. in all the kids shoes from baby to big kid there is only 1 size 12 and its for a preschool age. toddlers end at 10 then preschool begins from 10.5 to 3. hope that helps.
yea true, ok so these would be more for boys, not toddlers. Like I said my daughter wore them and I know that boys and girls sizes are different, that's why I really couldnt answer which age they would fit for a boy. So thank you. That helps big time!
