Foot

What It Is

Line drawing of the bones of the foot seen from the inside, with the arch shaded and a band of tissue running underneath it from the heel bone to the ball of the foot.
The plantar fascia runs under the arch from heel to toes — plantar fasciitis is usually felt where it meets the heel.

Plantar fasciitis is one of the most common causes of heel pain (American Academy of Orthopaedic Surgeons, n.d.). The plantar fascia is a strong, flat band of tissue (a ligament) that runs along the bottom of the foot and connects the heel bone to the front of the foot. It supports the arch in your foot (American Academy of Orthopaedic Surgeons, n.d.). Too much pressure on the plantar fascia can damage or tear the tissue, and the body's response is inflammation, which causes the heel pain. Tight calf and foot muscles can make it worse (American Academy of Orthopaedic Surgeons, n.d.). The pain is usually felt on the bottom of the foot near the heel, and is often worst with the first few steps in the morning or after a long rest, and after (rather than during) exercise (American Academy of Orthopaedic Surgeons, n.d.).

The condition is most common in people aged 40 to 60. It is also more likely in people who stand for long periods on hard surfaces, do a lot of high-impact activity such as running, are overweight, or have flat feet or a high arch (American Academy of Orthopaedic Surgeons, n.d.; NHS, 2025). You can get the condition in one foot or both feet.

Long-standing tension where the plantar fascia attaches to the heel bone can lead to a heel spur (a small bony growth). However, heel spurs do not cause plantar fasciitis pain, and most people who have a heel spur have no heel pain at all (American Academy of Orthopaedic Surgeons, n.d.).

Plantar Fasciitis Anatomy

The feet are full of flexible structures consisting of bones, muscles, ligaments, joints and other soft tissues that allow you to stand upright and perform activities such as running, walking and jumping. Three sections make up the feet:

  • The forefoot contains five longer bones and five toes.
  • The midfoot is a collection of bones forming arches in the feet. These include three cuneiform bones, the navicular bone and the cuboid bone.
  • The hind foot is composed of the ankle and the heel. The talus bone supporting the leg bones form the ankle. The heel bone is the largest out of all the bones in the foot.

Tendons, muscles and ligaments run along the surface of the feet, which allows all of the complex movements that are needed to maintain balance and motion. The Achilles tendon connects the calf muscle to the heel, which is essential for jumping, running and being able to stand on your toes.
