Plantar Fasciopathy in Runners: Symptoms, Causes and Evidence-Based Treatment
Plantar Fasciitis: A Runner's Guide to Heel Pain and Recovery

Struggling With Heel Pain?

​

If you experience sharp heel pain when taking your first steps in the morning, discomfort after long periods of sitting, or persistent pain during running, this guide is for you.

Plantar heel pain is one of the most common running injuries we see at Fit and Flex. Alongside Achilles tendinopathy, plantar fasciopathy accounts for approximately 6–24% of running-related injuries depending on the population studied (Mulvad et al., 2018; Lopes et al., 2012).

Below, we explain what plantar fasciopathy is, why it develops, how long recovery typically takes, and the evidence-based treatments that help runners return to training safely.

​

What Is The Plantar Fascia?

​

The plantar fascia, also known as the plantar aponeurosis (PA), is a thick band of connective tissue located on the sole of the foot. It originates from the heel bone (calcaneus) and extends toward the forefoot, where it divides into five bands attaching near the toes (Wearing et al., 2006; Ryskalin., 2024).

The plantar fascia consists of three distinct sections:

• Medial band

• Central band

• Lateral band

The central band is the thickest and most clinically significant portion, accounting for most plantar fascia injuries (Ryskalin., 2024).

​

What Does the Plantar Fascia Do?

​

The plantar fascia plays a critical role in supporting the arch of the foot. During walking and running, it functions through the windlass mechanism, tightening as the toes extend and helping maintain the longitudinal arch.

This mechanism:

• Prevents excessive arch collapse

• Assists foot stability during weight-bearing

• Contributes to subtalar joint supination during propulsion

• Helps transfer force efficiently during running

(Ryskalin., 2024)

​

How Common Is Plantar Fasciopathy?

​

Plantar fasciopathy is the most common cause of plantar heel pain and affects both athletes and non-athletes.

Research suggests:

• More than 1 million healthcare visits occur annually in the United States due to plantar fasciitis (Riddle et al., 2004)

• Lifetime prevalence is approximately 10% in the general population (Trojian & Tucker., 2019)

• It accounts for 6–24% of running-related injuries (Mulvad et al., 2018; Lopes et al., 2012)

• Up to 17.4% of runners experience plantar fasciopathy (Rhim et al., 2021)

• Recreational and elite runners show incidence rates between 5% and 10% (Trojian & Tucker., 2019)

• The condition is most common between ages 45 and 64 (Nahin, 2018)

• Women are approximately 2.5 times more likely to be affected than men (Nahin, 2018)

• Fifteen years after diagnosis, around 44% of patients still report some level of pain (Cooper, 2023)

Fortunately, with appropriate treatment, approximately 80% of patients improve within 12 months (Trojian & Tucker., 2019).

​

It's Not Just "Inflammation"

​

Historically, plantar heel pain was labelled plantar fasciitis, implying inflammation of the plantar fascia.

However, modern histological studies have found that many chronic cases demonstrate:

• Collagen degeneration

• Fibre disorganisation

• Increased mucoid ground substance

• Tissue thickening

• Calcification

Importantly, inflammatory cells are often absent on microscopic examination. This has led many researchers to favour the term plantar fasciopathy or plantar fasciosis, reflecting a failed healing response and tissue degeneration rather than a purely inflammatory condition (Ryskalin., 2024; Trojian & Tucker., 2019).

This shift mirrors what has occurred with Achilles tendinopathy and other chronic tendon disorders.

​

Symptoms of Plantar Fasciopathy

​

The hallmark symptom is pain at the underside of the heel, typically near the inner aspect of the calcaneus.

Common symptoms include:

• Sharp stabbing pain underneath the heel

• Pain during the first steps in the morning

• Pain after prolonged sitting or inactivity

• Tenderness at the medial calcaneal tubercle

• Pain that improves after walking for a few minutes

• Increased discomfort after prolonged standing

• Pain that worsens at the end of the day

• Symptoms aggravated by running or weight-bearing exercise

(Riddle & Schappert, 2004; Ryskalin., 2024)

Unlike nerve-related conditions, numbness and tingling are uncommon.

 

What Causes Plantar Fasciopathy?

​

The exact cause remains incompletely understood, but most researchers agree that plantar fasciopathy develops from repetitive mechanical overload exceeding the tissue's capacity to recover (Ryskalin., 2024).

Like Achilles tendinopathy, the condition is multifactorial, meaning several intrinsic and extrinsic factors usually contribute.

​

Biomechanical Risk Factors

​Research has identified several biomechanical contributors:

• Reduced ankle dorsiflexion, particularly less than 10° (Riddle et al., 2003)

• Flat feet (pes planus) (Trojian & Tucker., 2019)

• High arches (pes cavus) (Trojian & Tucker., 2019)

• Excessive subtalar joint pronation (Tahririan et al., 2012)

• Tight calf muscles

• Reduced Achilles tendon flexibility

(Ryskalin., 2024)

One of the strongest findings in the literature is the relationship between Achilles tendon tightness and plantar fascia strain. Tightness of the Achilles tendon is present in nearly 80% of individuals with plantar fasciopathy and is strongly associated with symptom severity (Ryskalin., 2024).

 

Modifiable Risk Factors

​Several lifestyle and training factors increase risk:

• Elevated BMI (>27 kg/m²) (Trojian & Tucker., 2019)

• Sedentary lifestyle (Trojian & Tucker., 2019)

• Excessive running volume (Trojian & Tucker., 2019)

• Sudden increases in training load

• Prolonged standing at work

• Intrinsic foot muscle weakness

• Calf muscle tightness

• Inappropriate footwear with poor support

(Trojian & Tucker., 2019)

 

Medical Conditions

​Certain medical conditions appear to increase susceptibility:

• Diabetes mellitus (Gariani et al., 2019)

• Rheumatological conditions affecting joints and connective tissues (Romero-López et al., 2021)

• Obesity

• Age-related tissue degeneration

(Robert et al., 2019)

​

Why Are Women More at Risk?

​

Women are approximately 2.5 times more likely to develop plantar fasciopathy than men (Nahin, 2018).

Several factors may contribute:

​

Footwear Choices

• High heels alter lower-limb biomechanics and increase plantar fascia loading (Wang et al., 2021)

• Unsupportive footwear may increase repetitive strain 

 

Hormonal Influences

Estrogen influences collagen metabolism and connective tissue function. Hormonal fluctuations may affect tissue elasticity and repair capacity.

 

Pregnancy

Pregnancy may increase risk due to:

• Increased body weight

• Ligament laxity

• Changes in gait mechanics

(Yalçınkaya et al., 2025)

 

Menopause and Perimenopause

Declining estrogen levels may contribute to:

• Reduced collagen synthesis

• Increased tissue stiffness

• Reduced elasticity and recoil

• Weight gain and altered biomechanics

(van Leeuwen et al., 2016; Kodoth et al., 2022)

 

How Plantar Fasciopathy Develops

​

The plantar fascia experiences substantial tensile loads during walking and running.

During the push-off phase of gait, the toes dorsiflex and tighten the fascia through the windlass mechanism (Tourillon et al., 2019).

When repetitive loading exceeds the tissue's capacity to repair:

1. Microscopic damage develops near the calcaneal attachment.

2. Collagen fibres become disorganised.

3. Degenerative changes accumulate.

4. The fascia thickens and becomes less efficient at transmitting force.

5. Persistent heel pain develops.

(Tourillon et al., 2019; Ryskalin., 2024)

This process closely resembles the pathology seen in chronic tendon disorders.

 

Conditions That Can Mimic Plantar Fasciopathy

​

Several conditions can present similarly and should be ruled out during assessment:

• Tarsal tunnel syndrome (Rodríguez-Merchán & Moracia-Ochagavía., 2021; Haq et al., 2024)

• Baxter nerve entrapment (Tedeschi et al., 2025)

• Calcaneal stress fracture

• Fat pad atrophy

• Subcalcaneal bursitis

• Plantar fascia tear or rupture

• Flexor hallucis longus tendinopathy

• Posterior tibial tendinopathy

• Rheumatoid arthritis

• Psoriatic arthropathy

• Seronegative spondyloarthropathies

• Sinus tarsi syndrome (NICE, 2024)

Heel spurs are commonly seen on imaging, occurring in approximately 50% of patients, but their clinical significance remains uncertain (Buchanan., 2024).

​

How Long Does Plantar Fasciopathy Take to Heal?

​

Recovery is often gradual rather than linear.

 

Current evidence suggests:

• Typical recovery: 3–6 months (Latt et al., 2020)

• Approximately 75% recover within 12 months (Buchanan., 2024)

• Between 90–95% achieve symptom resolution within 12–18 months (Lim et al., 2016)

 

Recovery depends on:

• Duration of symptoms

• Tissue degeneration severity

• Adherence to rehabilitation

• Biomechanical contributors

• Body weight and activity levels

Early intervention generally improves outcomes.

​

Evidence-Based Treatment for Plantar Fasciopathy

​

Research consistently supports a multimodal approach focusing on load management, mobility restoration, strengthening, and biomechanical correction.

 

What Works Best

​

Current evidence supports:

• Progressive loading exercises

• Calf stretching

• Plantar fascia-specific stretching

• Intrinsic foot muscle strengthening

• Load management and activity modification

• Footwear modification

• Orthotics or heel supports where indicated

• Manual therapy to improve foot and ankle mobility

(Trojian & Tucker., 2019; Ryskalin., 2024)

Improving Achilles tendon flexibility appears particularly important due to the strong mechanical relationship between Achilles loading and plantar fascia strain (Ryskalin., 2024).

 

The Fit and Flex Approach

​

At Fit and Flex, our treatment approach addresses both the painful tissue and the underlying biomechanical contributors.

​

Osteopathic Treatment

We use:

• Soft tissue mobilisation of the plantar fascia

• Calf muscle treatment

• Foot and ankle joint mobilisation

• Myofascial release techniques

 

Acupuncture

Acupuncture may be used alongside rehabilitation to help manage pain and improve comfort during recovery.

 

Rehabilitation

Our rehabilitation programmes focus on:

• Restoring the windlass mechanism

• Improving intrinsic foot muscle strength

• Enhancing calf and lower-limb capacity

• Addressing running biomechanics

• Improving lower-limb stability and force transfer

• Progressive return-to-running programmes

Research suggests that intrinsic foot muscles play an important role alongside the plantar fascia in creating the stiffness required for efficient push-off during running (Tourillon et al., 2019).

By addressing the entire kinetic chain rather than simply treating the painful heel, we aim to improve running efficiency and reduce recurrence risk.

 

FAQs

​

Is plantar fasciopathy serious?

Plantar fasciopathy is not usually dangerous, but it can significantly affect running performance, work, and quality of life. Without treatment, symptoms can persist for months or even years.

​

Can I keep running with plantar fasciopathy?

In many cases, yes. Running can often continue if symptoms remain manageable and do not worsen significantly during or after activity. Training volume may need modification while rehabilitation progresses.

 

Do orthotics help?

Orthotics, heel cups, and supportive footwear can reduce strain on the plantar fascia and may provide symptom relief. The best option depends on individual foot mechanics, training demands, and footwear choices.

​

What is the fastest way to recover?

The most effective recovery strategy combines:

• Progressive loading exercises

• Plantar fascia-specific stretching

• Calf flexibility work

• Foot strengthening

• Smart load management

• Biomechanical assessment and correction

Quick fixes are uncommon. Consistent rehabilitation over several months delivers the most reliable long-term outcomes.
