Risk Factors Associated With Plantar Fasciitis
Age

Although plantar fasciitis can arise without an obvious cause, certain age groups are more likely to develop it than others. Plantar fasciitis most commonly develops when an individual is between forty and sixty years old. But why is this?
Well, heels have a pad of fat that protects them and absorbs the shock when individuals walk or run. As the body grows older, the thickness of this fat decreases, which puts more pressure on the tissue. This chronic pain can also affect the elderly, as the muscles in the calves become weaker and tighter as individuals progress through life. The inflammation associated with plantar fasciitis can cause severe problems with walking and moving, warranting wearing orthotic implants.
Tight Achilles Tendons

Tight Achilles tendons can cause individuals to develop plantar fasciitis. Several scenarios can cause the Achilles tendon to tighten. Some individuals may have naturally tighter Achilles tendons. The tendon may also become tighter and harder to stretch if individuals wear heels for prolonged periods. Runners may find their Achilles tendon becomes tight and sore after long-distance running or short-distance sprinting. If individuals overuse their Achilles tendon, they may develop Achilles tendonitis. This occurs commonly in runners who have increased their run duration or intensity. Individuals with Achilles tendonitis may also develop plantar fasciitis due to the overuse of their leg muscles.
