What these researchers should have done was use epidemiological field research techniques in tracking down the women and men with osteoarthritis in their knees and finding out their use of high heels in detail. Then, draw conclusions from this data. I am curious to find out the percentages of these women and men who actually wore high heels, whether they wore chunky or stiletto high heels, the number hours they stood and walked in high heels, and whether the men thought they looked good in high heels. Also, this study did not consider how people's weight might affect their knees. This greater flexibility allow women to get up on their toes and do ballet on pointe dancing, while men can not.
Weight can stop a freight train.
Excess weight can damage people's legs, especially the knees. I would also like to find out from these women and men who have osteoarthritis in their knees, what their history of being overweight is. This article reviews some interesting survey results of 160 women by the St Barnabas Clinic in Oxford, England. It also mentions that children's feet are not fully developed until they are 18. 18 is the earliest age mentioned in my book that girls should try to wait until before wearing high heels, at least on a regular basis.
