This is the exercise programme we give every customer who writes in with plantar fasciitis. It is short on exercises and long on reasoning — because the exercises themselves are not the point. The progression is.
Three phases. Each phase has a specific job. The only wrong version of this programme is the one where you skip phase 2 because you're feeling better and go straight back to running. We'll get to that.
One note before we start: if you have any red flags — severe pain, fever, sudden onset without trauma, heel pain that is constant rather than loading-related — skip the programme and see a clinician. Everything below assumes an uncomplicated, ordinary case of plantar fasciitis.
The principle behind the programme
Plantar fasciitis is, at its core, a load-tolerance problem. The tissue has stopped being able to handle the load you are giving it. The cure is not less load forever — it's rebuilding tolerance through progressive, measured loading [1].
This means the programme does three specific things, in order:
- Settle the tissue down so it can heal. This is phase 1.
- Reload it, heavily and slowly, to stimulate the fascia to remodel and regain tolerance. This is phase 2. It is the most important phase and the one most commonly skipped.
- Re-introduce the activity that provoked it at a pace the rebuilt tissue can accept. This is phase 3.
Skipping phase 2.
When the morning pain eases in weeks 2–4, most people stop exercising and start doing their sport again. The tissue isn't ready. It relapses. Phase 2 is where the actual durability gets built.
Phase 1 — Calm the tissue (weeks 0–3)
Goal: reduce pain enough to load the tissue in phase 2. Do these once per day, ideally in the evening.
Wall calf stretch
Hands on a wall, back leg straight, front leg bent. Push the back heel to the floor. Feel the stretch in the upper calf. Hold 45 seconds, each side, 3 rounds.
Bent-knee calf stretch (soleus)
Same setup, but bend the back knee slightly. This shifts the stretch to the lower calf (soleus). 45 seconds each side, 3 rounds.
Plantar fascia stretch (the DiGiovanni protocol)
Sit down. Cross the painful foot over the opposite knee. Pull the toes back toward the shin with your hand until you feel a stretch across the arch. Hold 10 seconds. 10 reps. This specific stretch was shown to outperform calf-stretch-only programmes [2].
Frozen-bottle roll
Freeze a water bottle. Sitting down, roll the sole of the foot over it. 5 minutes per foot. Cold + massage + compression, in one lazy move.
During phase 1, also reduce load. Cut your daily walking or standing volume by 20–40%. If you run, stop running. Swim, cycle, or row instead — none of those load the fascia. This is the hardest sell for most people and the most important one.
Phase 2 — Load the tissue (weeks 3–8)
This is where recovery actually happens. The Rathleff heavy-slow calf-raise protocol is the best-evidenced single exercise for chronic plantar fasciitis we have [3]. It is boring. Do it anyway.
High-load calf raises with towel under toes
Stand on a step. Roll a towel and place it under your toes so your toes are dorsiflexed — this pre-loads the plantar fascia. Lower your heel slowly below the step over 3 seconds, pause 2 seconds, rise over 3 seconds. 3 sets of 12, every other day. Add weight (hold a backpack, a kettlebell) once bodyweight is easy — you're aiming for a weight that makes 10–12 reps genuinely hard.
Single-leg balance with eyes closed
Stand on one foot. Close your eyes. Try to hold 30 seconds. Repeat 3 times per side. Wakes up the intrinsic foot muscles.
Toe spreads and curls
Try to spread your toes wide, then curl them under, 20 reps. Sounds silly. Restores intrinsic foot muscle function, which takes load off the fascia in daily walking.
Keep doing the phase 1 stretches as a warm-up before the strength work. They stay in the programme forever.
Heavy, slow calf raises with the toes blocked up are the closest thing we have to a magic bullet for chronic plantar fasciitis. Almost nobody does them.
— Maya Iwamoto, Head of ProtocolDuring phase 2 your day-to-day footwear matters more than usual. If you haven't already, this is when an arch-support insole in your daily shoes pays the biggest dividend — the calf raises can rebuild tolerance, but only if you aren't re-irritating the fascia every afternoon on unsupportive flats.
Phase 3 — Return to activity (weeks 8–12)
Add the activity you stopped back in, slowly. The 10% rule works well: increase your running distance, standing hours, or walking volume by no more than 10% per week. Keep doing the calf raises two or three times per week forever. Tendinous tissue loses adaptation quickly if you stop loading it.
Monitor one thing: morning pain the day after. If a run on Tuesday makes Wednesday morning's first step worse than the previous week's baseline, you went too far too fast. Drop volume 25% and climb again from there.
Troubleshooting
If you are 4–6 weeks in and nothing has shifted:
- Check your calf-raise form. Toes must be blocked up — if you let them drop, you are not loading the fascia. The eccentric must be slow.
- Check your evening volume. If you are standing all day and not reducing load, the calf raises can't catch up.
- Check your footwear. Worn-out trainers, flat dress shoes, or indoor barefoot time can undo the whole programme.
- Check your expectations. Chronic cases can take 3–6 months. The trend is what matters, not the week-by-week.
If you've genuinely run the programme for eight weeks with no meaningful improvement, it's time to see a podiatrist. A small number of people have contributing factors (a partial tear, a nerve entrapment, an atypical presentation) that require more than this programme can offer.
For everyone else — and that's most people — this is what works. Run it for 12 weeks. Keep the calf raises forever.
