A woman's size 8 shoe is about the same size as a big kid's size 6 1/2 or 7. The length of the woman's shoe is about 9 11/16 inches, while the kid's size 7 runs approximately 9 13/16 inches. There are slight variations depending upon the type of footwear and the manufacturer.
Women's shoe sizes are also easily converted to men's sizes. The size for women is about one size larger than for a man. Therefore, a woman's size 8 shoe is about the same length as men's size 7. However, standard men's shoes tend to be wider than women's shoes.
