Plantar Fasciitis: A Complete Guide to Heel Pain Relief

Reviewed by the FootWell editorial team · Edited by Mustafa Bilgic · Updated June 2026 · ~9 min read

That sharp stab under your heel during the first steps of the morning is the hallmark of plantar fasciitis — an irritation of the thick band of tissue running along the sole of your foot. The good news: roughly 90% of cases resolve with conservative care.

What is plantar fasciitis?

The plantar fascia is a strong, fibrous band that connects your heel bone (calcaneus) to the base of your toes, forming and supporting the arch of the foot. When it is overloaded, tiny tears and inflammation develop where the fascia attaches to the heel. The result is pain that is typically worst with the first steps after waking or after a period of rest, then eases as the tissue warms up.

It is one of the most common orthopaedic foot complaints, affecting an estimated 1 in 10 people at some point in life. Runners, people who stand all day, and those carrying extra weight are most often affected.

What causes plantar fasciitis?

Plantar fasciitis is an overuse injury — it builds up from repeated strain rather than a single event. Common contributors include:

• Sudden increases in running distance or standing time
• Tight calf muscles and Achilles tendons that pull on the heel
• Flat feet or high arches that change how load travels through the fascia
• Worn-out or unsupportive footwear
• Higher body weight, which raises the load on every step
• Occupations on hard floors such as nursing, retail and hospitality

Symptoms to recognise

The classic picture is sharp, stabbing heel pain that is worst with the first steps in the morning. Other signs include pain after (not usually during) exercise, tenderness when you press the inner part of the heel, and stiffness that loosens with gentle movement. Pain that is constant, throbbing, or accompanied by numbness suggests a different problem and warrants a professional assessment.

Proven home treatments

Most people improve with a consistent conservative routine over 6–12 weeks:

1. Rest and load management — reduce high-impact activity temporarily rather than stopping all movement.
2. Calf and plantar fascia stretches performed daily (see our dedicated stretching guide).
3. Ice the heel for 15 minutes after activity, or roll the arch over a frozen water bottle.
4. Supportive shoes and arch support — avoid flat, flexible shoes and barefoot walking on hard floors.
5. Over-the-counter orthotics or heel cups to cushion and offload the heel.
6. Night splints to keep the fascia gently stretched overnight for stubborn cases.

If symptoms persist beyond a few months, a podiatrist may discuss custom orthotics, physical therapy, corticosteroid injections, or shockwave therapy.

Preventing a recurrence

• Increase activity gradually using the 10% rule
• Replace running shoes every 500–800 km
• Maintain calf flexibility with regular stretching
• Keep a healthy body weight to reduce heel load
• Choose supportive footwear for long days on hard surfaces

Frequently asked questions

How long does plantar fasciitis take to heal?

With consistent conservative care most cases improve within 6 to 12 weeks, though stubborn cases can take several months.

Should I keep running with plantar fasciitis?

Reduce volume and intensity rather than stopping entirely. Sharp pain during a run is a sign to back off and prioritise stretching and support.

Are heel spurs the cause of the pain?

Often not. Many people with heel spurs have no pain, and many with plantar fasciitis have no spur. The fascia irritation is usually the pain source.
