What are the risk factors for plantar fasciitis?

The plantar fascia is a strong band beneath the foot that helps support the arch and absorb force. Repeated stretching or loading can irritate it, particularly when activity rises quickly. Running, walking long distances, dancing, or work that involves many hours on hard floors may increase strain.

Foot shape and movement also matter. Flat feet can allow the arch to drop more during walking, while high arches may absorb shock less efficiently. Tight calf muscles, reduced ankle flexibility, worn or unsupportive footwear, and excess body weight can add to the load. These factors raise risk but do not prove that heel pain is plantar fasciitis.

Increase walking or running gradually and alternate demanding sessions with easier movement. Calf and plantar fascia stretches, foot-strengthening exercises, and supportive footwear may help, especially when tailored by a physiotherapist. Avoid spending long periods barefoot on hard surfaces if that worsens symptoms. Look at the whole pattern: training load, work demands, ankle motion and foot control all guide a useful plan.

Arrange an assessment when heel pain persists, changes your walking, or returns each time activity increases. Seek prompt care after a sudden injury, or if the foot is markedly swollen, numb, weak, hot or red. Inability to bear weight or severe pain at rest deserves urgent evaluation because other foot conditions can look similar.

Ask whether your arch shape, calf flexibility, footwear or training pattern is contributing. Ask for a staged return to activity and whether you need an assessment for another cause of heel pain.
