# Statistics: Shoe Size and Foot

DENISE CAPALBO

Gender statistics is an area that cuts across traditional fields of statistics to identify, produce and disseminate statistics that reflect the realities of the lives of women and men, and policy issues relating to gender.

Women can still wear men's shoes, but the size they are accustomed to will be labeled differently in the men's sizes. Although the shoe size is related to the length of your foot, the sizes do not follow a direct formula. Subtract 1 1/2 from your size, if you are a size 6. Therefore, your equivalent men's size would be a 4 1/2.

Above is a dot graph showing the female comparison if she was to convert to a male shoe by length. It is a difference in length by a size and a

When the human foot is looked at over hundreds of thousands of years and the effect of pregnancy on the foot is considered, modern woman should have a foot longer and wider than males. This expectation stems from the fact that the feet of nearly all pregnant females widen to support the increased load, and because women carry this load in front, their center of gravity moves anteriorly and therefore the feet lengthen to maintain balance. Helping with this process is the pregnancy chemical relaxin, which causes ligaments to weaken and go lax. Below is our sizes incorporated with the averaged.

This distribution shaped left skewed graph shows the evidence of the drastic difference in average between the male and female shoe sizes.

Now just looking at the graph from the general average of both male and female, collectively, to see how close in average the 32 people would be, this is what I came up with.

The basic average for all 32 people combined was a size 9. The average shoe size for a male is 10 1/2 (USA). American women, on the average, wear a size 8 wide shoe. So again this has proven that for Nyke to make just one shoe is not a good business decision. There is just not a close compromise that can be reached that would be comfortable enough to justify wearing either a small or too big of shoe.

Always lean toward getting shoes that are a little bigger than ones
