Don't ask her shoe size

Weight and age have always been a touchy subject for women, but it seems feet can join that list as women need larger shoe sizes.

Women's average shoe size has increased from UK size four-and-a-half in 1990 to size six in 2011, according to a study carried out by Debenhams.

This is because both men and women getting bigger and taller because of modern diets and the lifestyle change.

Those women who wear size eight to nine feel particularly ashamed and often lie about it as having big feet is seen as masculine.

An article by the Daily Mail identified several celebrities that have particularly large feet such as Nicole Kidman and Paris Hilton who both wear size nine.

Demand for larger size shoes for women has increased to the point where shoemakers have increased production of larger sizes by 80 percent.

"At one time it would have been difficult for a woman to get a size six shoe. Now that is the norm," says Michael Paynton from the British Chiropody and Podiatry Association.

Thankfully, new materials and techniques means that fashionable shoes can be made durable at any size.
