High heels can cause foot numbness due to compression and decreased blood circulation. The ball of the foot, heel, and toes experience extreme pressure, leading to vasoconstriction and reduced oxygenation. Prolonged periods of poor blood flow damage delicate nerve endings, resulting in numbness, tingling, and pain. Ignoring proper foot care can lead to chronic symptoms, but consulting a podiatrist and making lifestyle changes can alleviate the issue. Regular stretching exercises and orthotics can also help mitigate the effects of high heel wear.
