Most people never think about their toes until something goes wrong. A stubbed toe, a bunion that makes shoes uncomfortable, or plantar fasciitis that makes the first steps of the morning miserable. By that point the damage is done and the toes, which should be functioning as active contributors to every step, jump, and push-off, have been neglected for years.
The toes are not passive structures at the end of the foot. They are the final contact point between the body and the ground during every step of walking, every stride of running, and every push-off in jumping and sprinting. Toe strength and mobility directly affect running efficiency, balance, injury resilience of the foot and ankle, and the health of structures as far up the chain as the knee and hip.
This guide covers the anatomy of the toes relevant to training, the best exercises for toe strength and mobility, and how to put them into a routine that actually makes a difference.
Why Toe Strength and Mobility Matter
Running push-off power: The final phase of every running stride involves a push-off through the toes, particularly the big toe (hallux). The flexor hallucis longus and flexor digitorum longus, the muscles that flex the toes, contribute significantly to the propulsive force of each stride. Weakness here reduces running economy and increases the load on the calf and Achilles.
Balance and proprioception: The toes contain a dense network of mechanoreceptors that provide the nervous system with real-time information about foot position and ground contact. Toe strength and mobility directly affect the quality of this proprioceptive input and therefore the quality of balance during dynamic movements.
Plantar fascia health: The plantar fascia runs from the heel to the base of the toes. Toe extension mobility, particularly big toe extension, tensions the plantar fascia through the windlass mechanism, which is a critical component of the foot’s arch support system during walking and running. Restricted big toe extension overloads the plantar fascia and is a primary contributor to plantar fasciitis.
Bunion prevention: The most common structural deformity of the big toe, hallux valgus (bunion), is partly driven by weakness of the abductor hallucis, the muscle that should pull the big toe away from the second toe. Targeted toe strengthening can slow or prevent the progression of early bunion deformity.
Ankle stability: The toe flexors cross the ankle joint and contribute to ankle stability during single-leg activities. Weak toe flexors reduce the ankle’s ability to resist inversion forces, increasing the risk of ankle sprains.
The Anatomy of the Toes Relevant to Exercise
The foot has five toes (digits). The big toe (hallux) has two bones (phalanges), while the other four toes each have three. The toes are moved by a combination of intrinsic foot muscles (muscles that originate and insert within the foot) and extrinsic muscles (muscles that originate in the lower leg and whose tendons cross the ankle to reach the toes).
Key muscles for toe exercises:
Flexor hallucis longus: The primary flexor of the big toe. Originates in the posterior lower leg and runs behind the ankle to the underside of the big toe. Critical for push-off power in running and jumping.
Flexor digitorum longus and brevis: Flex the lesser toes (2 to 5). The longus originates in the lower leg, the brevis in the heel bone. Both contribute to push-off and to gripping the ground for stability.
Extensor hallucis longus and extensor digitorum longus: Extend the toes upward. Important for foot clearance during the swing phase of running and for the windlass mechanism.
Abductor hallucis: Pulls the big toe away from the second toe and supports the medial longitudinal arch. Weakness here contributes to bunion formation and arch collapse.
Lumbricals and interossei: Small intrinsic foot muscles that control the fine positioning of each toe. Often severely underdeveloped in people who wear rigid or narrow shoes.
How to Assess Toe Strength and Mobility
Big toe extension test (windlass mechanism):
- Stand barefoot and place a small object (a pen) under the big toe, elevating it
- Observe whether the arch of the foot rises when the big toe is extended
- A visible arch rise confirms an intact windlass mechanism
- If the arch does not rise, big toe extension mobility or plantar fascia function is compromised
Toe spread test:
- Sit barefoot and attempt to spread all five toes as wide apart as possible
- Most people find this extremely difficult, particularly spreading the little toe away from the others
- Inability to spread the toes indicates intrinsic foot muscle weakness and poor toe motor control
Single toe flexion:
- Place the foot flat on the floor
- Attempt to flex only the big toe downward while keeping the other toes still
- Then attempt to lift only the big toe while keeping the other toes on the floor
- These isolated movements are very difficult for most people and reveal the degree of toe motor control available
Towel scrunch test:
- Place a small towel flat on the floor
- Attempt to scrunch the towel toward you using only the toes
- Inability to scrunch effectively indicates toe flexor weakness
Toe Exercises
Mobility Exercises
Toe Circles
Purpose: Improves joint mobility in the metatarsophalangeal joints (the knuckle joints of the toes) and distributes synovial fluid before loading.
How to do it:
- Sit with the foot resting on the opposite knee
- Hold the base of one toe firmly between the thumb and index finger
- Slowly circle the toe in one direction 5 times
- Reverse direction for 5 circles
- Work through all five toes per foot
Big Toe Extension Mobilisation
Purpose: Improves big toe extension range, which is critical for the windlass mechanism and for running push-off mechanics. Restricted big toe extension is one of the most common and most impactful foot mobility limitations in runners and athletes.
How to do it:
- Sit with the foot resting on the opposite knee
- Hold the big toe and gently pull it upward into extension
- Hold for 10 seconds at the comfortable end of range
- Release and repeat 5 times per foot
- Progress to performing this standing, placing the big toe against a wall and gently leaning into the extension
Toe Flexion Mobilisation
Purpose: Improves the downward flexion range of the toes, which is needed for push-off and for gripping the ground during balance activities.
How to do it:
- Sit and cross one foot over the opposite knee
- Hold all five toes and gently bend them downward into flexion
- Hold for 10 seconds and release
- Repeat 5 times per foot
Plantar Fascia Stretch With Toe Extension
Purpose: Stretches the plantar fascia through the windlass mechanism by extending the toes while also stretching the calf and Achilles.
How to do it:
- Kneel on the floor with toes tucked under (toes in extension, balls of the feet on the floor)
- Sit back onto the heels, allowing the body weight to stretch the plantar fascia and toe flexors
- Hold for 30 to 60 seconds
- Repeat 2 to 3 times
Key cue: This can be intense, particularly for people with tight plantar fascias or restricted toe extension. Start with less bodyweight by supporting some weight through the hands and progress to full bodyweight over several sessions.
Strengthening Exercises
Towel Scrunch
Purpose: Strengthens the toe flexors (flexor digitorum brevis and lumbricals) through a functional gripping movement. One of the most effective toe strengthening exercises for people new to foot training.
How to do it:
- Place a small towel flat on the floor
- Place the bare foot on the towel
- Scrunch the towel toward you using only the toes
- Release and repeat
- Complete 3 sets of 15 scrunches per foot
Progression: Once the towel scrunch feels easy, perform the exercise on a slightly thicker or heavier towel, or use the toes to pick up small objects (marbles, pens) from the floor and place them in a bowl.
Marble or Object Pickup
Purpose: Develops fine motor control of individual toes and strengthens the lumbricals and interossei through gripping and releasing small objects.
How to do it:
- Place 10 to 15 marbles or small objects on the floor
- Use the toes of one foot to pick up each marble and place it in a bowl
- Complete with one foot then switch
- Perform this exercise 2 to 3 times per week
Toe Spread and Control
Purpose: Develops the intrinsic foot muscles responsible for toe abduction and individual toe control, which are severely underdeveloped in most people who wear shoes regularly.
How to do it:
- Sit barefoot with the foot flat on the floor
- Spread all five toes as wide apart as possible
- Hold for 3 seconds
- Bring the toes back together
- Complete 15 repetitions per foot
Progression (short foot exercise):
- Sit with the foot flat on the floor
- Without curling the toes, attempt to shorten the foot by pulling the ball of the foot toward the heel
- This activates the intrinsic foot muscles including the abductor hallucis
- Hold for 5 seconds and release
- Complete 10 repetitions per foot, progressing to standing and eventually single-leg standing
Big Toe Press
Purpose: Isolates the flexor hallucis longus and brevis, the primary propulsive muscles of the big toe. This exercise directly develops the push-off strength used in running and jumping.
How to do it:
- Stand barefoot with equal weight on both feet
- Press the big toe firmly into the floor without curling the other toes or lifting the heel
- Hold for 5 seconds and release
- Complete 15 repetitions per foot
Key cue: The other toes should remain relaxed and flat on the floor. If they curl or the arch of the foot lifts significantly, focus on isolating the big toe press before progressing.
Towel Scrunch Standing
Purpose: Performs the towel scrunch exercise under partial bodyweight loading, significantly increasing the demand on the toe flexors.
How to do it:
- Stand barefoot on a small towel
- Scrunch the towel toward you using the toes while supporting bodyweight through the foot
- Complete 3 sets of 15 per foot
Toe Yoga (Big Toe Lift and Little Toe Lift)
Purpose: Develops independent control of the big toe and the lesser toes, which is a specific skill that transfers to running mechanics and balance.
Big toe lift:
- Place the foot flat on the floor
- Lift only the big toe while keeping the other four toes on the floor
- Hold for 3 seconds and lower
- Complete 10 repetitions per foot
Little toe lift:
- Place the foot flat on the floor
- Lift only the four lesser toes while keeping the big toe on the floor
- Hold for 3 seconds and lower
- Complete 10 repetitions per foot
Key cue: These movements are genuinely difficult for most people and require patience. Most people initially find it impossible to isolate one toe group from the other. Improvement comes within 2 to 3 weeks of daily practice as the neuromuscular connection develops.
Calf Raise With Toe Emphasis
Purpose: Integrates toe flexor strength with calf and Achilles loading in the functional push-off position used in running and jumping.
How to do it:
- Stand with feet hip-width apart
- Rise onto the balls of the feet and the toes, pressing the toes firmly into the floor throughout
- At the top of the calf raise, actively press the big toe and all toes into the floor as hard as possible
- Hold for 2 seconds at the top
- Lower slowly
- Complete 3 sets of 12 reps
Key cue: The toe press at the top of the calf raise is what makes this exercise different from a standard calf raise. The active pressing of the toes into the floor at the top activates the toe flexors in the position most relevant to running push-off.
Balance Exercises With Toe Emphasis
Single-Leg Balance With Toe Spreading
Purpose: Combines the proprioceptive demand of single-leg balance with active toe spreading, which significantly increases the engagement of the intrinsic foot muscles during the balance task.
How to do it:
- Stand on one leg with a slight bend in the knee
- Actively spread all five toes as wide apart as possible during the balance hold
- Hold for 20 to 30 seconds per side
- Complete 3 holds per side
Key cue: The toe spread significantly increases the difficulty of the balance because it activates the intrinsic muscles and changes the proprioceptive input from the foot. Most people find single-leg balance noticeably more challenging when actively spreading the toes.
Single-Leg Calf Raise With Toe Control
Purpose: Develops toe flexor strength and balance simultaneously in a single-leg position that replicates the demands of running push-off.
How to do it:
- Stand on one leg, holding a wall lightly for balance support
- Slowly rise onto the toes and ball of the foot
- At the top, press the toes firmly into the floor and hold for 2 seconds
- Lower slowly
- Complete 3 sets of 12 per leg
A Structured Toe Exercise Routine
Daily routine (5 minutes, can be done while sitting at a desk or watching TV):
- Toe circles: all toes, both feet
- Big toe extension mobilisation: 5 x 10-second holds per foot
- Toe spread and control: 15 reps per foot
- Big toe press: 15 reps per foot

- Single-leg calf raise with toe control: 3 x 12 per leg
How Toe Exercises Connect to Running and Sport
The connection between toe strength and running performance is one of the most underappreciated relationships in athletic conditioning. Research has found that toe flexor strength is significantly correlated with running economy, with stronger toe flexors producing more efficient push-off mechanics and reduced oxygen cost at the same running pace.
For jumpers, the toe flexors contribute to the final extension of the foot during takeoff. Weakness here reduces jump height and reduces the reactive spring of the foot during plyometric movements.
For anyone dealing with plantar fasciitis, Achilles tendinopathy, or shin splints, addressing toe strength and mobility is frequently a missing piece of the rehabilitation puzzle. The toe flexors, when weak, force the plantar fascia and Achilles to absorb more of the propulsive load during each stride, contributing to overuse in these structures.
Frequently Asked Questions
How long does it take to build meaningful toe strength?
Most people notice improved toe mobility and motor control within 2 to 3 weeks of daily practice. Meaningful strength improvements, measurable as improved towel scrunch performance and better single-leg balance, typically develop over 4 to 6 weeks of consistent work. The neuromuscular control improvements (toe yoga, independent toe movements) often come faster than the strength improvements.
Do I need to be barefoot to do toe exercises?
Yes, for all of the exercises in this guide. The intrinsic foot muscles are activated most effectively when the foot is in direct contact with the floor without the constraint of a shoe. Performing toe exercises in shoes significantly reduces the effectiveness of the intrinsic muscle work. Spending more time barefoot in general, even just walking around the house without shoes, accelerates toe strength development.
Can toe exercises help with bunions?
Early-stage bunions respond well to toe strengthening, particularly the abductor hallucis exercises (toe spreading, short foot exercise, and big toe press). These exercises strengthen the muscle that should be pulling the big toe away from the second toe. They do not reverse existing structural deformity but can slow progression and reduce discomfort. Established bunions with significant structural change are less responsive to exercise alone.
Will toe exercises help with plantar fasciitis?
Yes, significantly. The plantar fascia works in concert with the toe flexors and the windlass mechanism during walking and running. Strengthening the toe flexors reduces the load on the plantar fascia by sharing the propulsive work of each stride. The big toe extension mobilisation and the plantar fascia stretch with toe extension are particularly relevant for plantar fasciitis management.
Why can I not spread my toes individually?
This is extremely common in people who wear shoes regularly. Modern footwear, particularly shoes with narrow toe boxes, compresses the toes together and prevents the intrinsic foot muscles from moving the toes independently. The muscles are there but the motor control and strength to use them has atrophied from years of disuse. Daily toe spreading and toe yoga practice restores this control within weeks.
