Running With Plantar Fasciitis

In this article, I’m going to be exploring plantar fasciitis in some detail, looking at how to treat this common running injury, and trying to answer the question: “can I run with plantar fasciitis?“.

I’ll be discussing when running with plantar fasciitis might be ok, versus when you simply have to stop running and rest and allow your body to heal. If your pain continues to worsen, stop and rest.

The short answer is: You can potetially continue to run with plantar fasciitis, as long as your pain remains at 5 or below on a 0-10 scale, and settles by the next day.

What is plantar fasciitis?

Plantar fasciitis is a condition so common in athletes it’s even been called runner’s heel. It creates pain in the sole of the foot, where the plantar fascia a thick tissue on the sole of the foot, attaches to the heel bone. The plantar fascia is sometimes aggravated by walking barefoot or sports involving running.

The plantar fascia is made up of three bands of tough fibrous tissue extending from heel bone to multiple attachments in the metatarsals (bones at the base of the toes). Of these three bands, the central band is considered most important in plantar fasciitis, the lateral band is very variable and not fully formed in many people while the medial band is very thin at its attachment to the heel bone.

I should point out at this stage that I’ve probably got the title wrong…

We should really be calling plantar fasciitis ‘fasciopathy‘ or ‘fasciosis‘.

When a word ends in ‘itis’ it suggests inflammation, and research has indicated that plantar fasciopathy probably doesn’t involve inflammation (Lemont et al 2003).

Let’s keep it simple and stick with the common term, plantar fasciitis, as it’s what most runners (and physios for that matter!) are familiar with.

Plantar fasciitis is said to affect more than 1 million people per year (Goff and Crawford 2011) and while it does tend to be self-limiting and resolve in 6-18 months (Wearing 2006), it can be a long and frustrating process, especially for an athlete.

Understanding the pathology is key to managing the condition but can be complex and challenging to understand (by ‘pathology’ we mean what is actually going on with the tissues).

Wearing (2006) describes common tissue changes in plantar fasciitis:

“Collagen degeneration with fibre disorientation, increased mucoid ground substance, angiofibroblastic hyperplasia and calcification are the most frequently reported findings.”

Unless you study histology I doubt that clarifies much!

A simplification would be to say there are changes where the plantar fascia attaches to the heel bone (an area known as the enthesis). These changes involve thickening of the tissue and disruption of the fibres which make up the fascia (collagen).

In degenerative cases this can involve the development of blood vessels within the fascia in areas that usually have limited blood supply, this is called neovascularisation or angiofibroblastic hyperplasia.

Calcification refers to parts of the tissue changing to become more bone like in nature, this can happen in plantar fasciitis with the development of a bony ‘heel spur’ – a small bony projection on the heel bone. However, heel spurs can be present in patients without plantar fasciitis so they may not be relevant to the pathology.

These changes share a lot in common with another group of conditions – tendinopathy. In fact the plantar fascia shares a lot of similar features to tendon.

Both thicken in response to excess load and both show a non-inflammatory reaction that can progress to degenerative change. They also have similar structures and display ‘viscoelastic’ properties during loading.

In recent years the work of Cook, Purdam, Magnusson and co. has advanced our understanding of tendon pathology. This progress has resulted in fundamental changes in how we manage tendinopathy. Plantar fasciopathy hasn’t enjoyed as much of the lime light and as a result there are still many questions about how best to manage it.

There are certainly many overlaps between tendinopathy and fasciopathy, this begs the question: should we approach plantar fasciitis in a similar way to tendinopathy?

At present I think there can be a ‘one size fits all’ approach to plantar fasciitis. Standard advice and stretches are given, sometimes regardless to the stage of the condition.

In fact, at the NHS Trust I previously worked in, plantar fasciitis was managed with telephone advice and a standardised exercise sheet. I’m hoping that following a similar reasoning process as exists in tendinopathy rehab might improve our management of plantar fasciitis.

So how do we go about doing this? Key features in tendinopathy are determining the stage of the tendinopathy, modifying both tensile and compressive load and promoting tendon adaptation through appropriate loading exercises.

Can we apply these to Plantar Fasciitis?

What are the different stages of plantar fasciitis?

Cook and Purdam (2009) highlighted the importance of determining the ‘stage’ of a tendinopathy in determining management. They suggested that clinically 2 broad stages could be used – reactive/ early dysrepair and degenerative/ later dysrepair.

In the reactive stage the tendon responds to excessive load by thickening and stiffening which helps act as a stress shield to decrease load.

Unfortunately this process usually results in pain but is reversible and settles when the excessive load is removed. In degeneration the tendon structure changes and there is change in the collagen which makes up the tendon.

For more on this read staging of tendinopathy.

Scott Wearing is widely published in plantar fasciitis research. He suggests in his excellent 2006 paper that there is similarity between the response of plantar fascia and tendon. This could mean that plantar fasciitis also goes through stages along a similar continuum.

All that jargon aside where does it leave us with managing plantar fasciitis?

Well, I would suggest it may be helpful to stage plantar fasciitis in a similar way – determine if it is in an acute ‘reactive’ stage or a more chronic ‘degenerative’ stage and vary your management accordingly.

The reactive response usually occurs after a fairly rapid increase in loading so if you’ve not had plantar fasciitis before and it’s developed as you’ve increased your running distance or introduced new training it’s more likely to be reactive.

Degenerative change usually happens after prolonged overloading. If you’ve had grumbly heel pain for a while which has gradually worsened and you’re an older athlete it is more likely a more degenerate picture.

How to treat plantar fasciitis

In the reactive stage treatment will largely centre around reducing load on the plantar fascia. This can be achieved by reducing activities that increase pain such as walking barefoot and running.

Taping the fascia can also help. Stretching the Achilles is widely recommended for plantar fasciitis but it might be best avoided in the reactive stage as it places greater stress on the fascia. In tendinopathy ‘load management’ is key in the reactive stage and the same is true of plantar fasciitis.

With more chronic degenerate plantar fasciitis load management is still key but can involve a gradual increase in load on the plantar fascia. This will probably involve stretching of the plantar fascia itself as well as the Achilles’ tendon.

Strengthening calf muscles and tibialis posterior may also help these muscles to manage load associated with impact during running to prevent recurrence. Again if we take the lead from tendinopathy management we have some guidance in terms of pain and exercise.

Can you run through plantar fasciitis?

Research on achilles tendinopathy by Silbernagel (2007) found that people could continue sport as long as they aimed to keep their pain below 5 out of 10 (where 0 is no pain and 10 is worst pain you can imagine) and pain had reduced by the next morning.

You could certainly apply this concept to plantar fasciitis. Indeed, many runners continue to run with their symptoms. However, I would urge caution with this, as running with plantar fasciitis hasn’t been widely studied.

Types of loading

When we consider the stress on a tendon or the plantar fascia with often think of tensile load which places a stretching force on the tissue. Until fairly recently compression has been overlooked but Cook and Purdam (2012) highlight the importance of compressive load.

Tensile load on the plantar fascia is thought to be created by something described as the ‘windlass mechanism‘ and can be increased by achilles tendon tightness. However according to Wearing (2006) compressive load has not been fully examined in plantar fasciitis. Perhaps future research will shed light on this.

A number of factors will play a part in loading – your training type, volume and intensity will have a role as will footwear and training surface.

There can be a connection between barefoot running and plantar fasciitis as this promotes forefoot striking and increases load on the calf complex.

Harder surfaces like road may have a larger ‘ground reaction force’ than grass or off-road training placing more load on the fascia. Try to spot patterns between changes you’ve made and changes in symptoms.

This can help you identify a cause to your plantar fasciitis and potential solutions.

What Causes Plantar Fasciitis

Several risk factors have been identified in plantar fasciitis and generally these link to increase load on the fascia;

  • Obesity – BMI over 30
  • Achilles tendon tightness
  • Reduced ankle dorsiflexion (the upward movement)
  • Foot posture? High arches and excessive pronation have both been linked to Plantar Fasciitis and are listed as risk factors by Goff and Crawford (2011). However there is some debate in the literature as few empirical studies have demonstrated a clear connection between plantar fasciopathy and shape of the arch of the foot.
  • Excessive load through sport or occupation – especially prolonged standing or distance walking/ running.

Addressing these factors will likely reduce load on the plantar fasciitis allowing the tissue to heal.

Plantar Fasciitis Stretches

Stretching the calf muscles has been a cornerstone of plantar fasciitis rehabilitation for years. Many articles in the literature recommend it alongside traditional exercises like rolling your foot over a frozen bottle of water.

Despite its popularity there is a sparsity of quality evidence supporting calf stretches for plantar fasciitis. The theory is that a tight achilles increases load on the fascia so we stretch it to reduce load. The problem is there is some debate whether stretching will actually achieve this.

A big question too is why stretch a condition that is usually aggravated by tensile load?

Cole et al. (2005) reviewed the evidence base for treatment of plantar fasciitis and reported “the benefits of stretching both the plantar fascia and achilles tendon are unknown”.

That said I do feel achilles stretches have a role in more chronic cases where you are aiming to gradually increase load on the fascia.

There is some evidence that stretching the plantar fascia itself may be more effective – DiGiovanni et al. (2003) found fascia specific stretches were superior to achilles stretching in treating chronic plantar fasciitis. Their follow up study (DiGiovanni et al. 2006) revealed marked long term improvement with specific plantar fascia stretching.

Whether you can actually ‘stretch’ the fascia remains a subject of debate but this intervention does seem to help symptoms.

Research Limitations

Many aspects of plantar fasciopathy have not been extensively studied. My thoughts here come from the perspective of a reasoned way of managing a condition heavily linked to overload with many similarities to tendinopathy.

It’s based on general theories on how tissues respond to load and how treatment often involves ‘optimal loading’ of the tissue to stimulate recovery.

However, without a sound evidence base this can only really be theory and opinion in relation to plantar fasciopathy. Indeed while there are similarities to tendinopathy (which has been used as a framework to guide some of these ideas) there are differences too.

The use of isometric and eccentric exercise has become a key factor in managing tendinopathy, this is difficult to achieve with plantar fascia. The pathology of tendinopathy and fasciopathy differ too so questions remain on how much of what we’ve learned from tendon studies can be applied to plantar fasciitis.

Summary

It can be helpful to think of plantar fasciopathy as a response to excess load. This can be an acute response that will settle with temporary reduction in load or a more chronic response that requires a gradual re-introduction to loading.

Modifying sporting activities to find a level that doesn’t aggravate symptoms is key to management. There are similarities with tendinopathy that might help guide us in some respects but this approach is not evidence-based.

In 2003 the Cochrane Collaboration did a systematic review of interventions for treating plantar heel pain. The work, by Crawford and Thompson reported,

“At the moment there is limited evidence upon which to base clinical practice”

They updated the review in 2010 but it was later withdrawn as it was substantially out of date! This highlights a big gap in the research for this common and complex condition.

And finally…

Plantar fasciopathy is not the only potential cause of heel pain and is frequently misdiagnosed.

With any lingering injury, it is sensible to seeking a professional opinion to clarify diagnosis and management. As ever with injury management if in doubt get it checked out!

  1. Great article. A NICE recommended treatment which is very effective is Shockwave Therapy.
    It is very effective at all stages of plantar fasciitis pain.

  2. My PF is currently fading. I took a whole week of rest and deep tissue massage using a tennis ball (which is now egg shaped as a result. Applying that much pressure was painful at first, but had immediate result). Stretching was OK. After a week I did a fast 8k run. The day after was slent with multiple massages. Going from there, I’ve been able to increase mileage and speed while reducing pain, mainly by keeping an eye on the pain level. Appears to match this article nicely.

  3. Hi Guys,
    I’ve been suffering with PF for 10 months now and I’m still non of the wiser, Ive been to my GP on many occasions but the NHS don’t have the resources or time to help me. I work in manufacturing and so i walk on concrete floors approx 4/5 miles per day, i also stand a lot.

    Ive tried Naproxin (helps but resumes when not taking)
    X-Ray No stress fracture but a heal spur is present.
    Cortisone injection,didn’t help.
    Consultant (told me he can’t help me).
    Physio
    Stretching and strength building using many of your videos.
    Podiatrist, still working with him.
    Orthotics (helped a little)
    Strassburg sock, (helps a little)
    Golf ball
    Ice filled water bottle.
    Taping (helped a little)

    I haven’t run since September

    I am currently paying private for Shockwave therapy and have just had my second session, my foot is sore for 24/48hrs after treatment but the pain does seem slightly reduced, I am worried that this isn’t going to work and it’s costing me a small fortune.

    Can you offer me any advice, I have a busy schedule next year and as previously said I haven’t run since September, it really is having a massive impact on my life now.

    Any advice would be greatly appreciated.

    Best Regards

    Paul

    1. Hi Paul, it’s now April so I don’t know if you’re still having trouble, but let me tell you briefly what worked for me. I suffered from PF for about two years. After a year and a half with a podiatrist, I tried physical therapy. And by tried, I mean three times a week for three months. That was about $2000, yes its going to cost money. My foot was taped almost 24/7 for two of those months. I had custom orthotics made (soft ones by the PT, not hard ones by the podiatrist). I bought Vionic flip flops and was NEVER without supportive footwear, even in the shower. On top of that I soaked my feet in warm water every morning immediately after getting out of bed. Then I did stretches while they were warm. Massages constantly throughout each day. My feet were my life for that period of time, but it healed me. I’m getting back into running now! Also, get off EVERY medication. I was hooked on ibuprofen for a while and I swear it hindered my rehab. Ice ice ice. Good luck!

      1. Hi April,
        Is your Plantar still going good? do you have any other suggestions? I know its been almost a year but I was hoping to see if you had any new advice.

        Thanks,
        Michelle

    2. No MRI on that list. I’m so sensitive that my stress fracture didn’t show up until I had the MRI. You can pay out of pocket these days and schedule your own. It was 3 months in, with 12 weeks in a boot, no relief. Crazy painful. I made the ortho CAST me. One little step on that foot, and they told me I’d be back to day 1 of non-weight bearing for six weeks. I healed perfectly!!!!!!!!! Get the MRI. Broken bones need six weeks to heal! Nothing else will help

  4. Hi Emily,

    Great info, thank you for posting this. I have just begun developing PF for the first time (I’m 49). I became a triathlete last year, so I am starting to feel the pressures on my body….tendonitis in any form is tough to treat for sure. Ice is definitely key! Thanks again!

  5. I have an FC, well not sure since doctors don’t know.
    I only have pain in the morning, I have not run in 2 month, I was wondering if it’s ok for me to run, since I don’t have pain while running…
    Thanks for a nice article!!

  6. Hi James, really well balanced article and informative. Currently 2 weeks into treatment and possibly going to try a XC Parkrun to see how it is.

    Having done the exercises for 2 weeks every morning I am managing the symptoms and pain is down at 1-2. Will start to work on strengthening it from next week if run goes well.

  7. Had PF a few years ago and an exercise of over stretching the big toes x 3/day. That seemed to wok as it went as quickly as it came. Now have Heel Spur which feels very similar. Having treatment/exercising it regular and surprised about how ‘high’ the stretches go (Glut, IT band etc).Had the sput for over a year and it seems to be subsiding a little however, if I’m out and about I’m always on the look out for a chair since standing for any period I find I’m moving from one foot to the other all the time. hope it goes soon, really had enough of it now and it sounds so insignificant but quite debilitating.

  8. My advice to anyone with PF is to use the entire panoply of massage balls, cricket balls, softballs, tennis balls all of differing tensions as one of them will get to the root of the pain. I also found standing on my bed mattress incredibly helpful. 🙂 Essentially, what you want is for your foot to regain natural movement around a surface with the necessary give and take to support, massage and ultimately strengthen against. I don’t know if it was because the last ball I used or if I’d used it first, would’ve worked regardless but the very soft balls small children use to play indoor tennis worked miracles on my foot and I was back running two days after first using having not run for 10 weeks in all kinds of pain.
