Plantar fasciitis (say “PLAN-tar fash-ee-EYE-tus”) is the most common cause of heel pain. The plantar fascia is a fibrous, flat band of tissue (ligament) that connects your heel bone to your toes. It supports the arch of your foot. If you strain your plantar fascia, it can get weak and you may develop tiny micro tears at the heel bone. The most common location for plantar fascia tears are at the “origin of insertion”. The origin is where the plantar fascia connects to the heel bone.
