why are my feet so sore

Feet can become sore for many reasons including overuse, wearing ill-fitting shoes, inflammation of the plantar fascia (plantar fasciitis), flat feet, nerve damage, arthritis, injuries like stress fractures or sprains, infections, and foot deformities. Excessive standing, walking, or high-impact activities can also cause soreness. Wearing shoes that don't provide proper support or cushioning can exacerbate the problem. If foot soreness persists or worsens, it is important to see a healthcare professional for a proper diagnosis and treatment since the cause could be anything from muscle strain to a medical condition like arthritis or neuropathy.
