Which factor is a common cause of plantar fasciitis?

Plantar fasciitis is commonly caused by overuse and excess pressure on the heel, making this the correct answer. The plantar fascia is a thick band of tissue that runs along the bottom of the foot, connecting the heel bone to the toes. When this tissue experiences repeated strain or pressure, whether from excessive walking, standing for long periods, or engaging in high-impact activities, it can become inflamed, leading to the pain associated with plantar fasciitis.

Factors like high-impact activities can contribute to this overuse, but the key element here is the sustained pressure on the heel, which directly impacts the plantar fascia's integrity. Understanding this connection is essential for both prevention and management strategies for those susceptible or affected by the condition.
