The causes of heel fasciitis, in general, are the following: First, aging, as we get older, the flexibility and elasticity of the plantar fascia decreases, making it easier to develop plantar fasciitis. Second, overexertion, such as long-distance runners or people who often stand and walk too much are more likely to have heel fasciitis. Third, flat feet, also known as flat feet, because the arch is flat so that the plantar fascia contact with the ground when the pressure is too high, over time may appear heel fasciitis. Fourth, diabetic patients, because the foot small blood vessel occlusion will lead to local ischemia of the fascia, when fatigue or after prolonged standing easily cause heel fasciitis.
