Hallux rigidus is a degenerative condition of the first metatarsophalangeal joint, the big toe knuckle joint, that produces progressive stiffness and pain with big toe extension. The name translates directly from Latin: hallux means big toe, rigidus means stiff. It is the most common arthritic condition of the foot, affecting approximately 1 in 40 people over the age of 50, though it regularly presents in younger athletes who have experienced repeated trauma to the big toe joint.
If you have hallux rigidus, you already know what it feels like. The ache at the top of the big toe joint during push-off. The catching sensation when the toe is forced into extension. The way it limits your squat depth, your running stride, and any activity that requires loading through a bent big toe. What you might not know is that targeted exercise is one of the most effective tools for managing hallux rigidus, slowing its progression, and maintaining athletic performance despite the condition.
What Hallux Rigidus Is and Why It Matters for Athletes
The first metatarsophalangeal joint is the hinge between the first metatarsal bone of the foot and the proximal phalanx of the big toe. Normal extension range at this joint is approximately 60 to 70 degrees, which is the range required for the push-off phase of walking and running and for the squat pattern in strength training.
In hallux rigidus, degenerative changes in the joint cartilage produce bone spurs (osteophytes) on the top of the joint that physically block extension range. The result is a progressive reduction in big toe extension that follows a predictable pattern: from mild stiffness with pain at the end of extension range in early-stage disease, through to complete loss of pain-free extension in advanced disease.
Why this matters athletically:
Running: Each running stride requires approximately 60 degrees of big toe extension during push-off. When this range is restricted, the body compensates by supinating the foot (rolling outward) to avoid loading the stiff joint, which alters the entire kinetic chain from the ankle to the hip.
Squatting: The squat pattern requires big toe extension as the knee tracks forward over the toes. Hallux rigidus restriction forces compensatory heel rise, excessive trunk lean, or lateral weight shift during squatting movements.
The windlass mechanism: The plantar fascia tightens when the big toe extends, creating the arch rigidity needed for efficient push-off. When big toe extension is restricted by hallux rigidus, this mechanism is impaired and the foot’s natural spring is reduced.
Grading Hallux Rigidus
Hallux rigidus is graded from 0 to 3 based on the severity of symptoms and structural changes:
Grade 0: Mild stiffness and occasional pain at the end of big toe extension range. Full or near-full range maintained.
Grade 1: Mild to moderate stiffness, pain with passive extension, early bone spur formation. Extension range reduced but functional range for walking maintained.
Grade 2: Moderate stiffness, pain through a significant portion of extension range, visible bone spur formation, extension reduced to 20 to 40 degrees.
Grade 3: Severe stiffness, pain through almost all extension range or only in end range, significant bone spur formation, extension severely restricted or absent.
The exercises in this guide are most effective for Grade 0 to 2 hallux rigidus. Grade 3 disease may require surgical assessment alongside conservative management.
Exercises for Hallux Rigidus
Mobility Exercises
The goal of mobility work in hallux rigidus is to maintain the available extension range, prevent further restriction from soft tissue tightening around the stiff joint, and reduce the pain associated with joint stiffness through movement-induced synovial fluid distribution.
Manual Big Toe Extension Mobilisation
Purpose: Directly maintains and attempts to improve the available extension range at the first metatarsophalangeal joint. The most important exercise in the hallux rigidus management programme.
How to do it:
- Sit with the foot resting on the opposite knee
- Place one hand on the first metatarsal head (the ball of the foot behind the big toe) to stabilise it
- Use the other hand to gently grasp the base of the big toe
- Slowly and gently pull the big toe upward into extension
- Hold at the comfortable end of range for 10 seconds
- Release and repeat
- Complete 10 repetitions per foot, 2 to 3 times per day
Key cue: The stabilising hand on the metatarsal head is critical. Without it, the movement comes from the entire foot rather than from the joint itself. Hold the metatarsal head firmly on the floor or against the opposite knee throughout.
Pain guidance: A mild aching sensation at the end of range is acceptable and expected. Sharp pain or a catching sensation means you have reached the bony block of the bone spurs and should reduce the range.
Progression: Once comfortable with passive mobilisation, add a gentle oscillatory movement at the end of range, small rhythmic pulls into extension rather than a sustained hold. This oscillation technique is a standard joint mobilisation approach that can produce greater range improvements than sustained holds alone.
Big Toe Circles
Purpose: Takes the first metatarsophalangeal joint through all available planes of movement, distributing synovial fluid and maintaining the non-extension planes of motion that are often neglected.
How to do it:
- Hold the big toe as in the extension mobilisation
- Draw slow circles with the big toe, moving through flexion, lateral deviation, extension, and medial deviation in sequence
- Complete 5 circles in each direction
- Perform 2 to 3 times per day
Key cue: Move only within the comfortable range. Hallux rigidus primarily restricts extension, so the circles will be smaller in the extension direction than in other directions. This asymmetry is expected.
Towel Toe Curl With Extension
Purpose: Moves the big toe through its available flexion and extension range under the gentle resistance of a towel, developing both mobility and the beginning of strengthening work.
How to do it:
- Place a small towel flat on the floor
- Use the toes to scrunch the towel toward you (flexion)
- Then spread the toes and attempt to extend the big toe as the towel releases
- Repeat 15 times per foot
Plantar Fascia and Toe Flexor Stretch
Purpose: Releases the plantar fascia and toe flexor tightness that develops secondary to hallux rigidus as the foot compensates for reduced push-off range.
How to do it:
- Sit and cross one foot over the opposite knee
- Hold all five toes and gently pull them upward into extension
- Feel the stretch along the sole of the foot
- Hold for 30 seconds
- Repeat 3 times per foot, twice daily
Strengthening Exercises
Strengthening around the hallux rigidus joint serves two purposes: it supports the stiff joint by developing the surrounding musculature, and it addresses the compensatory weakness that develops in the foot and ankle from altered movement patterns.
Short Foot Exercise
Purpose: Activates the intrinsic foot muscles, particularly the abductor hallucis, which support the medial arch and reduce the compensatory loading on the big toe joint during push-off.
How to do it:
- 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
- Think of creating an arch under the foot by activating the small muscles of the sole
- Hold for 5 seconds and release
- Complete 10 repetitions per foot
- Progress to performing standing and then single-leg standing
Big Toe Press
Purpose: Strengthens the flexor hallucis brevis and the intrinsic muscles of the big toe in the flexion direction, which is the direction of movement least affected by hallux rigidus and therefore the direction where strength development is most accessible.
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
- Hold for 5 seconds
- Release and repeat
- Complete 15 repetitions per foot
Calf Raise With Toe Modification
Purpose: Maintains calf and Achilles strength while modifying the top of the calf raise to avoid the painful end-range extension of hallux rigidus.
Standard modification:
- Perform a calf raise as normal
- At the top of the raise, keep the big toe slightly flexed rather than allowing it to extend fully into the painful range
- This maintains the training effect on the calf and Achilles while avoiding the painful impingement position
Further modification for more severe cases:
Perform the calf raise on a slightly elevated heel (a thin weight plate under the heel) which reduces the big toe extension demand at the top of the movement.
Towel Scrunch
Purpose: Strengthens the toe flexors in a functional gripping pattern that maintains foot strength without loading the painful extension range.
How to do it:
- Place a towel flat on the floor
- Scrunch the towel toward you using the toes, emphasising the big toe participation
- Complete 3 sets of 15 per foot
Tibialis Anterior Strengthening
Purpose: The tibialis anterior (the muscle along the outer shin) becomes important for hallux rigidus management because it controls dorsiflexion during the swing phase of walking, reducing the demand on the big toe to clear the ground. Strengthening it reduces the compensatory toe drag that worsens big toe joint irritation.
How to do it:
- Sit with the heel on the floor, foot relaxed
- Dorsiflex the foot (pull the toes and foot upward toward the shin) against light resistance from a band around the foot
- Hold for 2 seconds and lower slowly
- Complete 3 sets of 15 per foot
Load Management Exercises
These exercises maintain athletic performance while modifying the load through the big toe joint to avoid aggravating the condition.
Modified Squat (Heel Elevated)
Purpose: Allows continued squatting training while reducing the big toe extension demand that is the primary pain trigger in hallux rigidus.
How to do it:
- Place a thin weight plate (2.5 to 5 kilograms) under each heel
- Perform the squat as normal
- The heel elevation reduces the big toe extension demand at the bottom of the squat while maintaining the training stimulus for the quads, glutes, and posterior chain
Key cue: This is a management strategy, not a permanent solution. Continue working on big toe extension mobility alongside the modified squat to gradually reduce dependence on the heel elevation.
Split Squat With Rear Foot Elevated
Purpose: Allows single-leg lower body strength development while keeping the front foot (and its big toe) in a relatively neutral position with reduced extension demand.
How to do it:
- Elevate the rear foot on a bench
- The front foot remains flat on the floor with the toes relaxed
- Perform the split squat through the full range
- The rear foot elevation reduces the push-off demand on the front foot’s big toe
Step-Up
Purpose: Develops single-leg strength in a movement that places the foot on a flat surface rather than requiring the big toe extension of a push-off from the floor.
How to do it:
- Place one foot fully on a box or step
- Drive through the elevated foot to step up
- The big toe remains in a relatively neutral position on the flat step surface throughout
- Complete 3 sets of 10 per leg
Swimming and Cycling
Both swimming and cycling allow cardiovascular and lower body conditioning with minimal big toe extension demand. Swimming is the most joint-friendly option. Cycling requires the foot to push through the pedal stroke without the push-off extension of running and is well-tolerated by most people with hallux rigidus.
What to Avoid With Hallux Rigidus
Running through significant pain: Running requires repeated big toe extension loading. Running through significant pain accelerates cartilage damage and bone spur formation. Modifying running technique or temporarily reducing running volume is preferable to running through pain.
Barefoot running on hard surfaces: The impact and push-off demands of barefoot running on hard surfaces load the hallux rigidus joint significantly more than cushioned footwear. Running with a rigid-soled or carbon plate shoe reduces big toe extension demand and is often better tolerated.
High-heeled push-off movements: Any exercise that requires rising onto the balls of the feet and pushing through the big toe in maximum extension (such as certain dance movements, some plyometric landings, and some yoga positions) should be modified or avoided during flare-ups.
Flexible minimalist footwear for running: Minimalist shoes require more big toe extension during push-off than standard running shoes and are poorly tolerated in hallux rigidus. A stiffer-soled shoe with a slight rocker geometry is the footwear modification most consistently recommended for hallux rigidus management.

Frequently Asked Questions
Can exercise reverse hallux rigidus?
Exercise cannot reverse the degenerative cartilage changes or resorb existing bone spurs. What it can do is maintain the available range of motion, prevent further restriction from soft tissue tightening, develop the surrounding musculature to reduce joint loading, and manage pain effectively. Many people with Grade 1 to 2 hallux rigidus manage their condition successfully with exercise and footwear modifications for years without requiring surgery.
Should I push through the pain with hallux rigidus exercises?
The distinction between productive discomfort and counterproductive pain is important here. A mild aching at the end of the extension range during mobilisation exercises is acceptable and is the expected sensation of working at the limit of available range. Sharp pain, a catching sensation, or significant pain that lingers more than 30 minutes after exercise means the exercise intensity or range was too aggressive and needs to be reduced.
What footwear helps most with hallux rigidus?
A stiff-soled shoe with a rocker bottom geometry is consistently the most helpful footwear modification. The stiff sole prevents the big toe from being forced into extension during push-off, and the rocker geometry allows the foot to move through the gait cycle without requiring big toe extension at all. Carbon plate running shoes are an effective option for runners, and many people find significant pain relief simply from switching to a stiffer-soled shoe.
Can I still run with hallux rigidus?
Many people with Grade 1 to 2 hallux rigidus continue running with appropriate footwear modifications and management. The key adaptations are a stiff-soled or carbon plate running shoe, a slightly shorter stride to reduce push-off extension demand, and avoiding running through significant pain. Running volume may need to be temporarily reduced during flare-ups. Grade 3 hallux rigidus with severe pain during running typically requires surgical assessment before return to running.
Is hallux rigidus the same as hallux valgus (bunion)?
No. Hallux rigidus is a stiffness and degenerative condition of the big toe joint characterised by loss of extension range. Hallux valgus is a structural deformity where the big toe deviates toward the second toe, producing the characteristic bump on the inner side of the foot. The two conditions can coexist but are distinct problems with different causes, presentations, and management approaches.
