Health concern: Plantar fasciitis

My health concern is plantar fasciitis. I've had foot problems since I was young and often visited the hospital, but after becoming an adult, I don't go frequently. However, when plantar fasciitis occurs while walking, I endure the pain and keep walking. If I endure it, the pain eventually subsides, but it's very painful. I also pay attention to insoles to avoid overstraining my feet. Is there a solution? I want to know any preventive measures.
