What Is Plantar Fasciitis?

Plantar fasciitis is one of the most common causes of heel pain, affecting runners, people who spend long hours on their feet, and sedentary individuals alike. The plantar fascia is a thick band of connective tissue that runs along the bottom of your foot, connecting the heel bone to the toes. It acts like a bowstring, supporting the arch of your foot and absorbing ground forces when you walk or run.

When this tissue is subjected to repetitive stress or overload, it can develop micro-tears and become irritated — a condition we call plantar fasciitis. Despite the "-itis" suffix suggesting inflammation, research increasingly describes this as a degenerative rather than purely inflammatory process, particularly in chronic cases.

The Classic Symptom: First-Step Pain

The hallmark of plantar fasciitis is a sharp, stabbing pain at the bottom of the heel — worst with the very first steps in the morning, or after a long period of rest. This happens because the plantar fascia shortens while you're off your feet, and then is suddenly loaded and stretched when you stand. Many people find the pain eases after a few minutes of walking, only to return after prolonged activity.

Who Gets Plantar Fasciitis?

Several factors are associated with increased risk:

  • Sudden increase in activity: Taking up running or increasing mileage too quickly
  • Prolonged standing: Occupations requiring many hours on hard floors
  • Foot mechanics: Both high arches and flat feet can alter load distribution through the fascia
  • Calf and Achilles tightness: Reduced ankle dorsiflexion increases strain on the plantar fascia
  • Inappropriate footwear: Poor support or sudden changes in heel height
  • Body weight: Higher load through the foot increases fascial stress

Diagnosis

Plantar fasciitis is usually diagnosed clinically — meaning a physiotherapist or doctor can confirm it based on your symptoms and a physical examination. Tenderness is typically pinpoint at the medial (inner) aspect of the heel, where the fascia attaches to the bone. Imaging is rarely necessary but may be used to rule out other causes, such as a heel stress fracture or nerve entrapment.

A bone spur on X-ray is sometimes found in people with plantar fasciitis, but it's worth knowing that many people have heel spurs without any pain — they are not the cause of the condition.

Physiotherapy Treatment

Physiotherapy is the primary treatment for plantar fasciitis and has a strong evidence base. A comprehensive programme typically includes:

Stretching

  • Plantar fascia-specific stretch: Before getting out of bed each morning, pull your toes back toward your shin and hold for 20–30 seconds. Repeat several times. This pre-loads the fascia before your first step.
  • Calf and Achilles stretching: Both standing gastrocnemius and seated soleus stretches to improve ankle mobility.

Loading Exercises

Research supports progressive loading of the plantar fascia as a key treatment component. Exercises such as single-leg heel raises (performed slowly, including lowering off a step) help remodel the tissue and build resilience over time.

Manual Therapy

Soft tissue massage, myofascial release to the calf complex, and joint mobilisation of the ankle and midfoot can all reduce pain and improve function.

Footwear and Orthotics

Your physiotherapist may advise on appropriate footwear or refer you for custom orthotics if foot mechanics are a significant contributing factor. This is supportive, not curative — loading exercises remain essential.

How Long Does It Take to Recover?

With consistent treatment, many people see meaningful improvement within 6–8 weeks. However, plantar fasciitis can be stubborn, particularly if it's been present for several months before treatment begins. Patience and consistency with your exercise programme are essential — rushing back to high-impact activity too soon is a common reason for setbacks.

When to Seek Further Help

If symptoms haven't improved after 3–6 months of physiotherapy, your physiotherapist or GP may discuss other options, including shockwave therapy (which has good evidence for chronic cases) or, rarely, surgical intervention.

Final Word

Plantar fasciitis is frustrating, but it is very manageable with the right approach. Early physiotherapy assessment and a commitment to your home programme give you the best chance of a full recovery and a return to the activities you enjoy.
