Plantar fasciitis: stretch the calf, load the foot

First-line care for plantar fasciitis is unusually specific and well evidenced, and most of it is not about the heel itself.

This isn’t a workout to push through. It watches how your body responds and adjusts as it goes.

“Some mornings my feet simply refuse. On those days the practice softens instead of pretending nothing is wrong.” Jordan K. · Plantar fasciitis

What it is

Plantar fasciitis is irritation of the thick band of tissue that runs along the sole of the foot from the heel to the toes. It is a loading problem rather than an inflammation problem in the usual sense: the tissue has been asked to tolerate more than it currently can, often after an increase in time on the feet, a change of shoes or surface, or a period of doing much less followed by a return to normal.

How it behaves day to day

The signature is the first few steps in the morning, or the first steps after sitting for a while. It eases as you move and often returns later in the day after a long period standing. Tight calves are extremely common alongside it, and are part of why the heel is loaded the way it is.

What tends to feed it

• ·A sudden increase in walking, standing or running
• ·Unsupportive footwear, or a change of shoe or surface
• ·Long periods of standing on hard floors
• ·Tight calves, which increase the load passing through the heel

What the research recommends

The reference document is the American Physical Therapy Association's clinical practice guideline for heel pain and plantar fasciitis, revised in 2023. It gives grade A, its strongest grade, to two things in particular: plantar fascia specific stretching and calf stretching, for both short and long term pain reduction. The 2023 revision also added a grade B recommendation that clinicians prescribe therapeutic exercise including resistance training for the muscles of the foot and ankle, which is the clearest published support for loading the foot rather than only protecting it. Manual therapy is recommended, and taping carries grade A explicitly in conjunction with other treatment. Orthoses are the one place the guideline recommends against something: a grade B says clinicians should not use them, prefabricated or custom, as an isolated treatment for short-term pain relief, and only a grade C says they may be used when combined with other treatments. Night splints get grade A, as a one to three month programme, specifically for people who consistently have pain with the first step in the morning, which is the pattern this page opens with. Nothing in it recommends rest. Separately, a 2015 randomised trial found high-load strength training using slow heel raises produced a Foot Function Index 29 points lower than plantar-specific stretching at three months, with no difference between the groups at one, six or twelve months.

   Heel Pain, Plantar Fasciitis: Revision 2023, APTA clinical practice guideline (Koc et al., JOSPT 53(12))

   Plantar fascia specific stretching and gastrocnemius and soleus stretching carry strong, grade A evidence for short and long term pain reduction; the guidance is activity modification rather than rest.

2. 2
   Rathleff et al., high-load strength training in plantar fasciitis (Scandinavian Journal of Medicine and Science in Sports, 2015)

   High-load progressive strength training, using slow heel raises, is part of treatment, so graded loading belongs in the plan.

Where Vinys is different

• ·Vinys routes plantar fasciitis towards loading rather than towards protecting, because that is what the guideline describes. An app that reacts to a foot problem by making everything softer is working against the evidence.
• ·Calf and foot-specific stretching are built in, which is the grade A part, rather than left to a generic lower-body stretch.
• ·The distinction between an irritable day and a settled day is made in the session, so forefoot loading is dialled back when symptoms are reactive rather than removed permanently.
• ·The foot work is graded, so heel raises progress as they become available rather than starting at a level that flares it.
• ·Where yoga meets physiotherapy: the stretching and the strengthening in one short session, at home, on the days it is worst.

A short session to try

1. 1

   Downward dog, hands on wall · 30 to 45 seconds

   Calf stretch at partial load, which is the grade A recommendation without the full body weight through the heel.

2. 2

   Heel raise with a block between the heels · 8 to 10 slow reps

   Foot strength and arch support, the graded loading side of the plan.

3. 3

   Heel raise · 10 to 12 slow reps

   The slow heel raise that the high-load strength training evidence is built on.

4. 4

   Butterfly · 45 seconds

   Settles the hips and lower body to finish, without asking anything more of the foot.

The full practice · 12 to 16 minutes
