High heels can shorten calf muscles,[link widoczny dla zalogowanych]
Long term use of high heels can alter the anatomy of the calf muscles along with aching feet and a variety of foot deformities,[link widoczny dla zalogowanych].
High heels put a lot of stress on the back and knees. Squeezing into high heels with narrow toe boxes can cause a condition called Morton's neuroma,[link widoczny dla zalogowanych], which is a painful thickening of tissue between the third and fourth toes. To investigate the association between high heels and its effect on calf muscles,[link widoczny dla zalogowanych], researchers from Austria followed 80 women aged 20 to 50 years,[link widoczny dla zalogowanych], who had been wearing heels of at least two inches almost daily for the last two years or more. Of those,[link widoczny dla zalogowanych], 11 said they experienced discomfort when walking in flatter shoes.
When compared with women who did not wear heels,[link widoczny dla zalogowanych], ultrasounds revealed the women who wore heels had calf muscle fibres that were 13 percent shorter,[link widoczny dla zalogowanych], while MRIs showed the Achilles tendon,[link widoczny dla zalogowanych], which attaches the heel bone to the calf muscle,[link widoczny dla zalogowanych], was stiffer and thicker.
The incline of high heels causes the calf muscles to contract. Over time,[link widoczny dla zalogowanych], this causes the muscle fibres to shorten and the Achilles tendon to thicken; therefore some women feel pain when they try to walk in flats or sneakers.
The above findings conclude that long-term use of high-heeled shoes induces shortening of the calf muscles and increases Achilles tendon stiffness,[link widoczny dla zalogowanych], reducing the ankle's active range of motion.
