Plantar fasciitis is inflammation of the plantar fascia – the thick band of tissue along the bottom of your foot that connects your heel bone to your toes. It causes stabbing heel pain that is typically worst with your first steps in the morning or after long periods of rest, and it is the most common cause of heel pain in adults.

Plantar fascia pain can range from a dull morning ache to sharp, debilitating heel pain that limits your ability to walk. The good news: with the right physiotherapy and home care plan, the vast majority of people recover fully within a few months.

Plantar fasciitis affects an estimated 10% of people at some point in their lives. It’s particularly common in runners, people who stand all day for work, and adults between the ages of 40 and 60. While the pain in the bottom of your foot can feel alarming, it is a well-understood foot and ankle condition that responds well to conservative treatment.

Anatomy: What Is the Plantar Fascia?

The plantar fascia is a strong, fibrous ligament that runs from your heel bone, also called the calcaneus, to the base of your toes. Its primary job is to support the arch of your foot and absorb the shock that comes with each step you take.

Think of it like a bowstring: it holds the curve of your foot under tension. When that tension becomes excessive – through overuse, poor biomechanics, or sudden changes in activity – the tissue can develop small micro-tears near where it attaches to the heel bone. Over time, this causes irritation and inflammation.

The plantar fascia works closely with surrounding structures, including the Achilles tendon and the calf muscles. Tightness in either of these can significantly increase the load on the plantar fascia, which is why calf flexibility is such an important part of treatment.

What Causes Plantar Fasciitis?

Plantar fasciitis typically develops from overloading the plantar fascia through repetitive stress over time, rather than from a single injury. Common plantar fasciitis causes and risk factors include:

Tight calf muscles or Achilles tendon
Limited ankle flexibility puts extra strain on the fascia with every step.

High arch or flat feet
Abnormal foot mechanics and overpronation, which means rolling inward, alter how weight is distributed across the plantar fascia.

Sudden increases in activity
Starting a new running program or increasing weekly mileage too quickly is a classic plantar fasciitis trigger for runners and can be considered a sports injury.

Standing all day
Prolonged standing on hard surfaces is common in retail, healthcare, teaching, and trades work.

Unsupportive footwear
Shoes lacking proper arch support or cushioning accelerate fascial breakdown.

Excess body weight
This increases mechanical load on the heel and plantar fascia with every step.

Age
The plantar fascia loses some elasticity from the mid-40s onward, making it more vulnerable to repetitive stress.

Is It Related to Heel Spurs?

Heel spurs are bony growths that can form on the heel bone where the plantar fascia attaches. They are often mentioned in the same breath as plantar fasciitis, but they aren’t the direct cause of pain – in fact, many people with heel spurs on imaging have no symptoms at all.

The pain of plantar fasciitis comes from fascial irritation, not the spur itself.

Plantar Fasciitis Symptoms

The hallmark symptom of plantar fasciitis is heel pain – specifically at the base of the heel where the fascia attaches to the heel bone. Pain in the arch of the foot and along the bottom of your foot is also common.

The symptoms follow a very distinctive pattern that most patients recognise immediately:

First-step morning pain
Sharp, stabbing pain with your first steps out of bed – usually the most severe symptom.

Pain after rest
Flares after sitting for long periods, then eases once you “warm up” and keep moving.

Activity-related pain
Increases during or after prolonged standing, walking, or running.

Localised tenderness
Tenderness when pressing on the inner edge of the heel or the bottom of your foot.

Callout Box

When to be concerned:
If your heel pain is constant, not worse with activity, comes with significant swelling, or doesn’t improve at all after a few weeks, see a physiotherapist promptly. These patterns can indicate a stress fracture or another condition that needs a different approach.

What Happens If Plantar Fasciitis Is Left Untreated?

Without treatment, plantar fasciitis can become chronic – lasting well over a year and becoming progressively harder to resolve.

Ongoing heel pain when walking can also alter your gait, placing extra strain on your knees, hips, and lower back. In rare cases, a chronically overloaded fascia can develop a partial plantar fascia tear.

Early intervention with a physiotherapist in Edmonton gives you the best chance of a quick, full recovery.

How Is Plantar Fasciitis Diagnosed?

Plantar fasciitis is primarily a clinical diagnosis – meaning a trained physiotherapist or physician can usually identify it through a physical assessment alone, without imaging.

Your physiotherapist will assess:

The location and behaviour of your pain
This includes morning stiffness, post-rest pain, and activity response.

Tenderness along the plantar fascia
Especially at the heel bone attachment.

Your ankle and calf flexibility
Limited flexibility can place more stress on the plantar fascia.

Your foot mechanics and arch structure
This helps identify whether flat feet, high arches, or overpronation are contributing.

Your gait pattern and footwear
How you walk and what shoes you wear can both affect recovery.

Imaging, such as an X-ray or ultrasound, is usually only ordered if the diagnosis is unclear, recovery is slow, or a stress fracture needs to be ruled out. An ultrasound can measure fascia thickness and confirm inflammation, while an X-ray can identify heel spurs.

Treatments for Plantar Fasciitis

The good news: over 90% of plantar fasciitis cases resolve with conservative, non-surgical treatment. Physiotherapy is the cornerstone of recovery.

In the early stages, applying ice for 15-20 minutes after activity and taking anti-inflammatory medication, if appropriate, can help manage acute pain while longer-term treatments take effect.

Here are the most effective approaches:

1. Plantar Fasciitis Stretches & Exercises

Plantar fasciitis stretches are the single most evidence-backed treatment available.

A daily stretching program should include the plantar fascia-specific stretch, where you pull your toes back, a towel calf stretch, and stair heel drops.

These exercises for plantar fasciitis work best when done first thing in the morning before standing, and repeated throughout the day.

2. Plantar Fasciitis Physiotherapy & Manual Therapy

Physiotherapy for plantar fasciitis typically involves 6-10 sessions, depending on severity.

A physiotherapist uses hands-on techniques including soft tissue massage, manual therapy, joint mobilisation, and dry needling / IMS to reduce pain and restore movement.

They’ll correct contributing biomechanical factors and build a progressive loading program tailored to your activity goals.

3. Orthotics & Supportive Shoes

Custom or off-the-shelf custom foot orthotics can redistribute pressure along the plantar fascia and support the arch.

Pair these with supportive shoes that offer good cushioning and arch support – and avoid walking barefoot on hard floors, especially first thing in the morning.

4. Night Splints

Night splints keep the foot in a slightly dorsiflexed position while you sleep, keeping the plantar fascia gently stretched overnight.

This reduces the intense first-step pain many patients experience every morning by preventing the fascia from contracting during rest.

5. Load Management & Activity Modification

Temporarily reducing high-impact activities, such as running and jumping, while maintaining fitness through swimming or cycling allows the fascia to heal without becoming completely deconditioned.

Your physiotherapist will help structure this properly.

6. Shockwave Therapy

For persistent cases lasting longer than 3-6 months, extracorporeal shockwave therapy / ESWT can stimulate healing in chronically inflamed fascia.

Research shows good results for patients who haven’t improved with standard care.

7. Advanced Options: Injections & Surgery

Corticosteroid injections may provide short-term relief in severe cases, though repeated injections can weaken the fascia.

Surgery, including gastrocnemius recession to release calf tightness, is reserved for the small number of cases that fail to respond after 12+ months of consistent conservative care.

Recovery: What to Expect

Recovery from plantar fasciitis varies depending on how long you’ve had it, how consistently you follow your treatment plan, and your individual risk factors.

Here’s a general guide:

Mild cases caught early:
6-8 weeks of consistent stretching and load management often leads to significant improvement.

Moderate cases:
3-6 months with physiotherapy, orthotics, and activity modification.

Chronic cases lasting 12+ months:
May require additional interventions like shockwave therapy, but still respond well to a comprehensive plan.

The single biggest predictor of a slow recovery is inconsistency with stretching. Most people improve dramatically once they build a daily calf stretch and plantar fascia stretch into their morning routine.

Prevention Tips

Once you’ve recovered from plantar fasciitis – or if you’re at risk – these strategies help keep it from coming back:

Daily stretching
Maintain a calf stretch and plantar fascia stretch routine, especially before your first steps in the morning.

Supportive footwear
Wear supportive shoes with adequate arch support and replace running shoes every 500-800 km.

Gradual training increases
Follow the 10% rule – never increase weekly running mileage by more than 10% at a time.

Maintain a healthy weight
Reducing excess body weight lowers the mechanical load on the plantar fascia significantly.

Vary your surfaces
Mix up running surfaces and avoid long sessions on concrete or asphalt where possible.

Address calf tightness
Regular calf stretching and foam rolling reduces the tension transmitted to the plantar fascia.

Frequently Asked Questions About Plantar Fasciitis

What exactly is plantar fasciitis?

Plantar fasciitis is inflammation of the plantar fascia – the thick band of tissue on the bottom of your foot that connects your heel bone to your toes. It causes stabbing heel pain, especially with your first steps in the morning.

How long does plantar fasciitis take to heal?

Most people recover within 3-6 months with consistent physiotherapy and home stretching. Some cases, particularly those left untreated for a long time, can take up to 12-18 months. Starting treatment early significantly speeds up recovery.

Can I keep running with plantar fasciitis?

It depends on severity. In mild cases, continuing low-impact activity with modifications is fine. In moderate to severe cases, temporarily reducing or replacing running with swimming or cycling allows the fascia to heal. Your physiotherapist can advise based on your specific situation.

Is plantar fasciitis the same as a heel spur?

No – but they’re related. A heel spur is a bony growth on the heel bone, while plantar fasciitis is inflammation of the soft tissue. Many people have heel spurs without any pain, and plantar fasciitis can occur without a spur present.

What’s the best stretch for plantar fasciitis?

The most evidence-supported stretch is the plantar fascia-specific stretch.

While seated, cross the affected foot over your knee, pull your toes back toward your shin until you feel a stretch along the bottom of your foot, and hold for 10 seconds.

Repeat 10 times, three times a day – especially first thing in the morning before standing.

Does plantar fasciitis go away on its own?

It can – but it’s slow without treatment, often taking 12-18 months. With physiotherapy, most people recover in 3-6 months.

Without addressing the underlying causes, such as calf tightness, footwear, and load, the condition frequently returns even after it resolves.

Is physiotherapy good for plantar fasciitis?

Yes – physiotherapy is consistently recommended as the first-line treatment for plantar fasciitis.

A physiotherapist can identify the root causes of your condition, guide you through an effective stretching and loading program, and use hands-on treatments to speed your recovery significantly.

What exercises should you avoid with plantar fasciitis?

During a flare-up, avoid high-impact activities like running on hard surfaces, jumping, and exercises that load the heel heavily, such as heavy calf raises through full range on a step.

Walking on tiptoe and long barefoot walks on hard floors can also aggravate the fascia.

Low-impact alternatives like swimming and cycling are generally well tolerated.

Is shockwave therapy good for plantar fasciitis?

Yes, particularly for chronic cases.

Shockwave therapy has strong clinical evidence for plantar fasciitis that hasn’t responded to 3-6 months of conservative care.

It stimulates the body’s healing response in the affected tissue and can significantly reduce chronic heel pain.
