Foot Strengthening Exercises for Runners: The Complete Breakdown
Most runners spend hours strengthening their glutes, quads and hamstrings, but almost no time on the muscles doing the most work on every single run: the feet.
Your feet absorb roughly three times your body weight with each step. For a 70kg runner clocking 40km a week, that is millions of kilograms of force every week, handled almost entirely by a collection of small muscles, tendons and connective tissue that most training programs completely ignore.
The result is a predictable cycle: tight calves, collapsed arches, arch pain, and eventually something that sidelines you for weeks.
This article covers the most effective foot strengthening exercises for runners, the mistakes that slow progress down, and how to build it all into your routine without adding an hour to your training week.
Why Foot Strength Matters More Than Most Runners Think
The foot has two groups of muscles: extrinsic (originating in the lower leg) and intrinsic (originating within the foot itself). The intrinsic muscles are the ones most runners have almost completely switched off, particularly if they spend most of the day in supportive footwear.
Research published in PubMed found that atrophy of intrinsic foot muscles is directly associated with plantar fasciitis symptoms in runners. In plain terms: weak feet get injured. Strong feet stay in the game.
When the intrinsic muscles are weak, the arch collapses under load, the plantar fascia takes on forces it was never designed to absorb on its own, and the whole kinetic chain above it (ankles, knees, hips) starts compensating. This is why runners often blame their knees or hips when the real problem started at ground level.
The Best Foot Strengthening Exercises for Runners
1. Short Foot Exercise (Arch Doming)
Why it works: This is the single most evidence-backed intrinsic foot muscle exercise available. It directly targets the muscles that support your arch during each ground contact.
How to do it:
- Sit or stand with your foot flat on the floor
- Without curling your toes, draw the ball of your foot toward your heel, creating a dome shape in the arch
- Hold for 5 seconds, then release
- Repeat 10 times per foot
Start seated, then progress to standing, then single-leg standing. The movement feels very small at first, which is normal. Most runners have very little neuromuscular connection to these muscles initially.
Frequency: Daily, or at minimum 3 times a week.
2. Heel Raises (Calf and Arch Loading)
Why it works: The calf complex and Achilles tendon work directly with the plantar fascia. Strengthening through the full range of motion, especially the lowering phase, builds the tendon capacity needed for higher mileage running.
How to do it:
- Stand with the balls of your feet on a step or slightly raised surface
- Rise up onto your toes slowly (2 seconds up)
- Lower your heels below the step level slowly (3 to 4 seconds down)
- Repeat 15 to 20 times
- Progress to single-leg once double-leg feels easy
The slow lowering phase (eccentric) is where most of the adaptation happens. Do not rush it.
3. Single Leg Balance Progressions
Why it works: Running is a series of single-leg landings. Training balance on one foot at a time recruits every stabilising muscle in the foot, ankle and lower leg simultaneously.
Progressions (easiest to hardest):
- Single leg stand on flat ground, 30 seconds each side
- Single leg stand with eyes closed
- Single leg stand on a folded towel or cushion
- Single leg stand on a curved or unstable surface
Frequency: 2 to 3 times per week as part of your warm-up or cool-down.
4. Resistance Band Foot Strengthening
Why it works: Adding resistance to toe flexion and ankle inversion and eversion builds the smaller stabilising muscles that standard exercises miss.
How to do it:
- Loop a resistance band around the ball of your foot
- Flex and extend the foot slowly against the band (10 to 15 reps)
- Rotate the ankle inward and outward against the band (10 to 15 reps each direction)
Toe resistance bands designed specifically for foot strengthening make this significantly easier to set up and progress than standard exercise bands.
5. High-Load Strength Training for the Plantar Fascia
Why it works: This is the most clinically supported exercise for runners dealing with plantar fasciitis, backed by a landmark 2015 study from Rathleff et al. that found high-load strength training produced faster pain reduction and better long-term outcomes than stretching alone.
It is worth understanding why. For a long time, plantar fasciitis was treated primarily as an inflammatory condition, with ice, rest and anti-inflammatory medication as the default response. Current research tells a different story. The fascia is now better understood as a structure that responds to load, and one that becomes painful when the load it is asked to handle exceeds what it has been conditioned for. That changes the approach entirely. The goal is not to reduce load but to increase the capacity of the tissue to handle it.
The key is the Windlass mechanism. When the toes are extended (pulled upward), the plantar fascia is placed under tension like a wound spring, increasing the load on it significantly during a heel raise. This is exactly the kind of progressive overload the fascia needs to adapt and become more resilient.
Standard heel raises load the calf and Achilles. High-load heel raises with toes elevated load all of that, plus the plantar fascia directly. For runners recovering from plantar fasciitis or trying to build capacity before it becomes a problem, this is the exercise to prioritise.
How to do it:
You need a surface that elevates and extends your toes while you perform a single-leg heel raise. A rolled towel works as a starting point, but it compresses under load, shifts position and gives you no real control over the angle. The Fasciitis Fighter ROUND 2 was specifically designed for this: a firm, curved EVA foam platform that holds the toes in consistent dorsiflexion throughout the movement, keeping the plantar fascia loaded correctly from the bottom of the rep to the top.
- Place your toes on the ROUND 2 (or a rolled towel) so they are extended upward at roughly 25 to 30 degrees
- Perform a slow single-leg heel raise: 3 seconds up, pause at the top, 3 seconds down
- Lower your heel below the platform level at the bottom for full range
- Complete 3 sets of 12 reps per foot
- Rest 2 to 3 minutes between sets
Progression over weeks:
- Weeks 1 to 2: Double-leg to learn the movement and find your position on the ROUND 2
- Weeks 3 to 4: Single-leg at bodyweight, 3 sets of 12
- Weeks 5 to 6: Add a weighted backpack (5 to 10kg) for the single-leg version
- Weeks 7 to 8: Increase weight or slow the eccentric phase to 4 to 5 seconds
Important notes:
Some discomfort in the arch during this exercise is expected and acceptable, particularly in the first few weeks. A pain level of 3 to 4 out of 10 during the exercise is fine. Pain above 5 out of 10, or pain that is significantly worse the following morning, means the load is too high and should be reduced.
The toe elevation is non-negotiable. A heel raise without it does not produce the same plantar fascia loading effect. The angle of the toes is what makes this exercise specific to the fascia rather than just the calf.
Frequency: 3 times per week with at least one rest day between sessions. This is a strength stimulus, not a daily mobility exercise. The tissue needs recovery time between sessions to adapt.
For runners dealing with persistent arch pain or plantar fasciitis, this single exercise done consistently and progressively over 8 weeks is one of the most effective things you can do. Combine it with the short foot exercise and single-leg balance work and you have the foundation of a complete foot strengthening program.
Common Mistakes Runners Make With Foot Strengthening
This is where most runners go wrong. The exercises above are straightforward. The mistakes below are what stop them from working.
Mistake 1: Only Stretching, Never Strengthening
Stretching the calf and plantar fascia is the default advice for foot pain in runners, and it has its place. But stretching alone does not build the capacity the foot needs to handle running loads. Flexibility without strength is a joint that can move through range but cannot control that range under force.
If you are only stretching and wondering why nothing is improving, this is likely why. Strengthening needs to be part of the picture, not an afterthought.
Mistake 2: Rushing the Eccentric Phase of Heel Raises
The eccentric (lowering) phase of a heel raise is where the tendon and calf complex actually adapt and get stronger. Most runners power up and drop back down quickly, cutting the most valuable part of the movement in half.
Slow it down to 3 to 4 seconds on the way down, every single rep. It will feel harder immediately. That is the point.
Mistake 3: Training Through Sharp Pain
Foot strengthening should create fatigue and a mild burn in the muscles being worked. It should not create sharp, stabbing or shooting pain. If an exercise produces that kind of pain, stop it and work around it.
Pushing through sharp pain during rehabilitation almost always extends recovery time. The foot responds much better to consistent, graded loading than to aggressive overwork.
Mistake 4: Expecting Results in a Week
Tendons and connective tissue adapt more slowly than muscle. Most runners doing foot strengthening consistently for the first time will not notice meaningful changes for 4 to 6 weeks. This is normal and not a sign that the work is not doing anything.
The runners who quit at week 3 because they do not feel different yet are the ones who end up back at square one 6 months later. Commit to 8 weeks before drawing conclusions.
Mistake 5: Relying on Orthotics Instead of Building Strength
Orthotics have their place in acute pain management and for specific structural issues. But using them as a long-term substitute for foot strength is like wearing a back brace instead of doing core work. The support feels good, but the underlying weakness remains.
If you have been in orthotics for months or years, the transition off them should be gradual and paired with a progressive foot strengthening program. Going cold turkey rarely works. Slowly reducing reliance while building strength does.
Mistake 6: Only Training in One Plane of Movement
The foot does not just move up and down. It rotates, inverts, everts and responds to ground surfaces that are never perfectly flat. Most standard exercises only train the sagittal plane (forward and back), leaving the stabilising muscles in the other directions underdeveloped.
Adding resistance band inversion and eversion work, and progressing single-leg balance onto uneven surfaces, addresses this gap and produces a much more resilient foot overall.
Mistake 7: Skipping the Morning Routine
The plantar fascia shortens overnight. The first steps of the morning are the highest-risk moment for people with arch pain or a history of plantar fasciitis. Going from lying down to immediately loading a cold, tight foot is a reliable way to set off symptoms.
Two minutes of arch mobility and short foot activation before you put weight through your foot in the morning makes a significant difference. It does not need to be a full session. It just needs to happen before your feet hit the ground.
How to Build Foot Strengthening Into Your Running Routine
The most common mistake is treating foot exercises as optional extras done when you remember. The runners who see the most benefit make them non-negotiable, built into existing habits.
A simple approach:
Morning (5 minutes): Short foot exercise and arch mobility before getting out of bed or while the kettle boils.
Pre-run (3 minutes): Single leg balance 30 seconds each side, then heel raises 15 reps to activate the calf complex.
Post-run (5 minutes): Resistance band work and a short foot cool-down while your heart rate comes down.
That is 13 minutes across the day. Most runners spend longer choosing their playlist.
Foot Strengthening for Common Running Injuries
Plantar Fasciitis
The most searched foot problem among runners. The plantar fascia is a thick band of connective tissue running along the bottom of the foot. When it takes on load it was not conditioned to handle, it becomes irritated and painful, typically worst in the morning or after periods of rest.
The current research is clear that plantar fasciitis is primarily a load capacity issue, not an inflammatory one. The fascia becomes painful when the demands placed on it exceed what it has been trained to handle. That means the solution is progressive loading, not rest alone. Strengthening the intrinsic foot muscles and building capacity through high-load exercises reduces the demand placed on the fascia itself. Most runners see meaningful improvement within 6 to 8 weeks of consistent strengthening.
Arch Pain While Running
Flat arches or collapsing arches under load are almost always a muscle weakness issue rather than a structural one. The arch is designed to be dynamic, rising and falling with each step, managed by the muscles underneath it. When those muscles are weak, the arch drops excessively, creating pain across the mid-foot.
The short foot exercise is the best starting point. Progress to loaded single-leg exercises as strength improves.
Shin Splints
Often linked to calf and ankle weakness rather than a shin problem. Heel raises, resistance band work and single-leg balance help address the underlying cause rather than just managing the symptom.
Achilles Tendinopathy
Heavy slow resistance loading of the calf complex through full range heel raises is the gold standard approach. Start double-leg, progress to single-leg, and prioritise the slow eccentric lowering phase.
How Strong Should Your Feet Actually Be?
A useful benchmark: you should be able to perform 25 single-leg heel raises on each foot without the heel drifting outward or the knee collapsing inward. If you cannot, your calf and foot complex has meaningful room to grow before adding mileage.
Another marker: you should be able to balance on one leg with eyes closed for at least 20 seconds. Less than that signals a proprioception deficit that will limit your ability to absorb and stabilise force during running.
The Bottom Line
Foot strengthening is not complicated, but it requires consistency and the right kind of load. Stretching has its place, but it is high-load strength training through the full range of the plantar fascia that actually builds resilience in the tissue.
The exercises above are low-tech and can be done at home or as part of your existing warm-up and cool-down. Avoid the common mistakes, commit to at least 6 to 8 weeks of progressive loading, and the return is fewer injuries, better running economy, and a foot that can handle the mileage you are chasing.
The Fasciitis Fighter ROUND 2 was built specifically for high-load plantar fascia strength training. Its curved EVA foam design holds your toes in the optimal position for the Windlass mechanism to engage, making it the most effective tool available for this kind of work at home. Used daily by runners across Australia and the US, it is the difference between guessing at the right angle with a rolled towel and training with a tool designed for exactly this purpose.
Start with the short foot exercise. Build toward the high-load single-leg work. Your feet will thank you by the time your next race comes around.
