It isn't so much the size, but the shape of the foot. A woman's foot is smaller and more narrow than a man's. Years ago one mold was used for athletic shoes, so the woman's shoes never did fit a woman's foot quite right. Now, they use a mold for women.
the sizes
I don't know about children's shoe sizes, but for adults, it is two sizes different. For example, if a woman wears a size 7 shoe, then she would wear a size 5 in men's shoes.
The difference between men and boys' shoe sizes is the number of the size. Men's shoe sizes generally start at number 6 and can be as high as 30. Boy's shoe sizes start at 0 and go up to the number 6. The average size shoe for men is 9.
The width ... "EE" is narrower than "EEEE".
It is an 8.5 shoe size in US women sizes.
Currently, the average shoe size for women in Canada is 6.5. In Centimeters, the average woman's shoe size is 38.5.
A 7.5 in men's shoes- American sizes, = a 8.5 to 9 in women's.
There is not much of a difference between Jordan's and Jay's. One is a running shoe the other is a jumping shoe.
American shoe sizes are a 1/2 size smaller
To convert american shoe sizes add 2 to the man's size to get the woman's size. Thus men's 9 is women's 11.
Spanish shoe size uses the European sizes so a 38 (Woman) would be an American Women's 7.5. Because of the difference in size and rate the size may vary a little but that's the most common converted size I've found online.
