In the United States, a woman’s shoe size 6.5 is about the same as a youth size 4.5. The 4.5 is a size for big kids, not toddlers or babies.
Know the size of the foot to convert a woman’s or man’s shoe size to a youth size. The length of a woman’s size 6.5 shoe is about 9.1 inches. Size 4, which is 8.75 inches, or size 4.5, which is exactly 9 inches, are the closest youth sizes. As women’s sizes go up, it gets harder to change them to youth sizes. For example, you can’t just switch from a woman’s size 8 to a youth’s size 8.
