Conventional Footwear

A study found that wearing heels above 5 centimeters for more than 2 years causes a significant reduction in calf muscle size and strength. Raised running shoe heels were originally introduced to reduce sudden Achilles strain for weekend runners. Heavily cushioned running shoes emerged around 1970. Thick-soled or elevated shoes interpose a cushion between foot and ground, degrading the proprioceptive signal the nervous system receives. Thick-soled conventional shoes degrade sensory information and encourage a higher-impact gait pattern. Conventional shoes, especially pointed-toe styles, compress toes into a narrow space that causes toe malalignment and disrupts gait mechanics. Chronically elevated heels can weaken the Achilles tendon and reduce range of motion over time. Arch support insoles may prevent active foot strength from developing by acting as an external crutch. High heels shift body weight forward, force the ankle into chronic plantarflexion, and alter spinal alignment. Altered gait from shoe use causes knee adduction, increasing shear force on the joint and contributing to knee pain.
