A pair of 5-inch stilettos can add the finishing touch to any outfit. After all, aren’t Louboutins and Manolos a girl’s best friend? But strutters beware: The “mile-long legs” effect from high heels could cause long-term back, ankle, and knee damage (not to mention that aching feet thing).

Hell on Heels — Why It Matters

According to Carrie Bradshaw, all women have the right to shoes. Carrie is also ignoring about 250 years of scientific inquiry into heelsA History of medical scientists on high heels. Linder, M., Saltzman, C.L. College of Law, University of Iowa. International Journal of Health Services: Planning, Administration, Evaluation, 1998;28(2):201-25. Before getting into a brawl over a pair of Jimmy Choos, take note that wearing heels (even ones less than an inch high) can cause muscle strain and possibly even permanent damage among frequent wearersModerate-Heeled Shoes and Knee Joint Torques Relevant to the Development and Progression of Knee Osteoarthritis.

Wearing high heels every day can shorten calf muscles by up to 13%, causing lower leg stiffness and limiting the ankle’s range of motionOn muscle, tendon and high heels.

Heels may give women a certain swish to their walk but that “je ne sais quoi” could cause some serious “dommage.” Heels change a person’s walking motion, increasing the amount of bone-on-bone forces in the knee which can lead to osteoarthritisWalking on high heels changes muscle activity and the dynamics of human walking significantly.

Studies also suggest stilettos can cause back problems and exacerbate existing ones.

To Heel With It — The Answer/Debate

Although it’s tempting to slip on those pumps before a night on the town, the achy pain experienced after the first few struts is a tell-tale sign something is wrong. Instead of heels, rheumatologists suggest wearing flat, flexible shoes with good arch support to ease stress on knee joints and lower body muscles. If heels are an absolute must, it’s best to wear them sparingly, since many of their biggest harms come via repetitive stress on the calves and knee joint.

Don’t want to sacrifice fashion for health? Try trading heels for a cute pair of flats or non-heeled boots to wear to work or for a night out. Perhaps someone better get Lady Gaga on the telephone about her choice of footwear.

Are high heels really worth the health risks? How do you cut the pain while walking tall? Let us know in the comments.
