Why Intrinsic Foot Strength Matters
The foot contains two groups of muscles: the extrinsic muscles (originating in the lower leg and controlling ankle and toe movement via long tendons) and the intrinsic muscles (originating and inserting entirely within the foot itself). The intrinsics — including the flexor digitorum brevis, the four lumbricales, the three interossei, and the abductor and flexor muscles of the hallux and fifth toe — are small but mechanically critical: they control toe position during push-off, provide real-time arch support during weight-bearing, and decelerate the rate of arch collapse in late midstance.
Modern footwear significantly reduces the demand on intrinsic foot muscles — thick soles, arch support, and toe spring all substitute for muscular work that the intrinsics would otherwise perform in minimally shod walking. The result, observed across decades of footwear biomechanics research, is measurably weaker intrinsic musculature in regularly shod populations compared to unshod or minimally shod populations. This weakness contributes to plantar fascia overload, forefoot instability, and reduced arch dynamic support.
Exercise 1: Arch Doming (Short Foot Exercise)
Arch doming — also called the short foot exercise — is the most evidence-supported intrinsic foot strengthening exercise. Technique: sit with the foot flat on the floor, knee bent to 90 degrees. Without curling the toes, contract the foot intrinsic muscles to shorten the foot and raise the arch — as if trying to bring the ball of the foot toward the heel without bending the toes. Hold for 5 seconds. Release. Perform 10 repetitions, 2 times daily. Progress to standing arch doming, then to single-leg standing (eyes open, then eyes closed) as strength improves.
The arch doming exercise specifically targets the flexor digitorum brevis and abductor hallucis — the intrinsic muscles most directly responsible for arch support. Clinical research shows that 8 weeks of arch doming significantly increases intrinsic muscle volume on MRI and reduces navicular drop (a measure of arch collapse) in runners with overpronation.
Exercise 2: Towel Scrunches
Place a small hand towel flat on the floor. Scrunch the towel toward you using only the toe flexors — pulling the towel under the foot while keeping the heel flat. Perform 3 sets of 20 scrunches per foot, 2 times daily. This exercise is particularly effective for building endurance in the intrinsic toe flexors (lumbricales and flexor digitorum brevis) and the short toe flexors (flexor digiti minimi, flexor hallucis brevis).
Exercise 3: Marble Pickups and Toe Spreads
Marble pickups: place 10–20 marbles on the floor. Using only the toes of one foot, pick up each marble and drop it into a cup. This exercises toe flexion and proprioceptive control of individual toe segments — improving the fine motor control of the intrinsic muscles that stabilize toes during push-off. Toe spreads: while seated, spread all five toes as far apart as possible (abduction) and hold for 5 seconds. Perform 10 repetitions. This specifically activates the toe abductors (abductor hallucis, dorsal interossei) that are often profoundly weak from narrow toe box footwear.
Progressing Intrinsic Strengthening
Initial intrinsic exercises are performed seated or standing with bilateral weight-bearing. As strength and motor control improve, progress to: single-leg standing balance (30 seconds each side, 3 repetitions), single-leg balance on a foam pad, and single-leg heel raises with toe flexion control. These progressions transfer intrinsic strength to functional weight-bearing activities that mirror the demands of running and sport.
Dr. Tom's Product Recommendations
Spiky Massage Ball Set (Foot Intrinsic Activation)
⭐ Highly Rated
Spiky massage balls for plantar activation and self-massage — rolling the sole of the foot on a spiky ball before intrinsic exercises activates neural receptors and prepares intrinsic muscles for strengthening work.
Dr. Tom says: “Rolling on the spiky ball before my toe exercises makes the intrinsic activation exercises much more effective.”
Pre-exercise plantar activation, plantar fascia self-massage, foot intrinsic warm-up
Patients with severe plantar fasciitis where direct plantar pressure causes significant pain

Yoga Toes Gems Toe Stretcher and Separator
⭐ Highly Rated
Toe spreading device that passively separates and realigns toes — stretches the interdigital muscles and toe abductors while providing gentle mobilization that complements active toe strengthening exercises.
Dr. Tom says: “Wearing these for 30 minutes after my toe exercises improved my toe splay dramatically over six weeks.”
Toe abductor stretching, bunion toe realignment, complement to active intrinsic strengthening
Patients with significant structural bunion deformity requiring surgical correction rather than conservative management

BOSU Balance Trainer (Balance and Intrinsic Progression)
⭐ Highly Rated
Hemispheric balance trainer for advanced intrinsic foot strengthening — single-leg standing on the BOSU dome-side maximally activates foot intrinsics and ankle stabilizers, providing the gold-standard proprioception challenge.
Dr. Tom says: “Adding the BOSU to my foot strengthening routine was the final step that got my plantar fasciitis completely resolved.”
Advanced intrinsic strengthening, proprioception training, ankle instability rehabilitation
Patients in the early or acute phase of intrinsic muscle training — begin with flat surface exercises first

✅ Pros / Benefits
- 8 weeks of arch doming measurably increases intrinsic muscle volume and reduces arch collapse in runners
- Toe strengthening exercises require no equipment and can be performed anywhere throughout the day
- Intrinsic strengthening reduces plantar fascial passive tension by increasing active arch support
- Progressive balance training transfers intrinsic strength to functional sport-specific movements
❌ Cons / Risks
- Intrinsic strengthening takes 8–12 weeks to produce measurable changes — requires consistent daily practice
- Exercises are adjunctive — intrinsic strengthening alone without stretching and footwear changes is insufficient for plantar fasciitis
- Arch doming requires careful instruction — most patients initially curl their toes instead of isolating the intrinsics
- Foot weakness is often bilateral even when symptoms are unilateral — both feet should be trained
Dr. Tom Biernacki’s Recommendation
The intrinsic muscles are the unsung heroes of foot health. When I see a patient with plantar fasciitis, I almost always find weak intrinsics on the same side — the arch isn’t supporting itself actively, so the passive fascia is doing all the work. Add the arch doming and towel scrunches to the stretching protocol, and the recovery is faster and more complete. It’s a simple prescription that pays real dividends.

Frequently Asked Questions
What are the best exercises to strengthen the feet?
The evidence-based foot strengthening exercises are: arch doming (short foot exercise) — 10 holds x 5 seconds, 2x daily; towel scrunches — 20 repetitions, 2x daily; toe spreads — 10 repetitions, 2x daily; marble pickups — 10–20 marbles per session; and progressive single-leg balance (floor, foam, BOSU). These exercises directly target the intrinsic muscles that support the arch and control toe function during running and walking.
Can toe exercises help with plantar fasciitis?
Yes. Intrinsic foot strengthening is an effective adjunct to stretching for plantar fasciitis — clinical research demonstrates that arch doming reduces navicular drop (arch collapse) and reduces passive plantar fascial load. The exercises work by building active muscular arch support that reduces the passive mechanical stress on the plantar fascia during walking and running.
How long does it take for foot strengthening exercises to work?
Measurable improvements in intrinsic muscle strength and arch control take 6–8 weeks of consistent daily exercise. Subjective improvements in foot stability and plantar fascia symptoms typically begin within 4–6 weeks. Like all progressive strengthening programs, consistency of daily practice is the most important determinant of outcome — skipping multiple days resets the adaptation process.
Should I do toe exercises barefoot or with shoes?
Intrinsic foot exercises are most effective when performed barefoot or in minimal footwear that allows full toe movement. Thick soles, toe spring, and arch support built into conventional shoes reduce intrinsic muscle demand and diminish exercise effectiveness. Beginning exercises seated and barefoot, then progressing to standing barefoot, maximizes the training stimulus to the intrinsic muscles.
