If we go back in time, somewhere near 1960 then women used to put on 6.5 size shoe which was equivalent to size 4 in United Kingdom, but let us not talk about the same size anymore, because shoes sizes have been changed dramatically, even in 70s size was changed from 6.5 to 7.5 in women.
And today with considerable change we notice size has changed to7.5 to 8.5 and even 9 for average American females.
Actual shoe size differs from country to country, and this has been an issue for a lot of people, not everyone can get through this if they do not know how to convert their shoe sizes.
So specifically you just have to know the values from the different chart, especially about your favorite shoes, such as Nike, new balance or any of your favorite shoes.
Average Shoe Size for Women in USA
The size number 7, 7.5, and 8 are most demanding shoes and reason must be because these are some common women shoe size in the US, and if we take a look back then we would come to know that about 7 years ago the common shoe size used to be about 6 and 6.5 which is a long gone case, of course shoe size has grown up with the time.
A theory that states why this is happening, people are getting taller due to the high nutrition in their food, which is not only making them healthy but also taller, so what happens if you get taller? Well, if you are taller then, you also tend to get larger foot, and that makes a big difference in shoe size, so that explains why the change has occurred, but that seems to be the only explanation to that.
