Risk Factors Associated With Plantar Fasciitis
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.
