Trigger toe is a real condition, and yes, you can get it. Medically called “hallux saltans” when it affects the big toe, trigger toe involves the same kind of catching and locking mechanism that most people associate with trigger finger. The condition is less common and less widely discussed than its hand counterpart, which means it sometimes goes unrecognized for months before someone gets a proper diagnosis. The underlying problem, how it develops, and who is most vulnerable are all worth understanding if you have toe pain that comes with a snapping or locking sensation.
How Trigger Toe Happens
The mechanism behind trigger toe closely mirrors what happens in trigger finger. Your toe flexor tendons run through a series of fibrous bands, sometimes called pulleys, that hold them close to the bone. When the tendon or its surrounding sheath becomes inflamed and thickened, the tendon can no longer glide smoothly through these narrow tunnels. Instead, it catches, producing the characteristic snap or lock when you try to straighten your toe.
In the big toe, the tendon involved is the flexor hallucis longus, a long tendon that runs from the calf all the way to the tip of the big toe. The most common site of catching is a fibro-osseous tunnel underneath a bony shelf on the heel bone called the sustentaculum tali.1PubMed. Hallux saltans due to flexor hallucis longus entrapment at a previously unreported site in an unskilled manual laborer: a case report At that point, the tendon passes through a tight channel, and any swelling or nodule formation on the tendon creates friction. The result is a toe that catches in a bent position and then pops or snaps when forced straight.
The condition generally starts as tendon inflammation. Repeated stress on the tendon can progress from straightforward tendinitis, where the pain and swelling are reversible, to a chronic stage where the tendon itself thickens, develops internal damage, or forms nodules. Once adhesions develop inside the tendon sheath, normal gliding is compromised and triggering begins.2Clinics in Podiatric Medicine and Surgery.

Who Is Most at Risk
Ballet dancers are the population most closely associated with trigger toe, and for a straightforward reason. Dancing en pointe forces the ankle and big toe into extreme downward flexion under the body’s full weight. That position puts enormous repetitive stress on the flexor hallucis longus tendon, particularly where it passes through the narrow tunnel behind the ankle. Researchers have documented cases of stenosing tenosynovitis in dancers attributable directly to this demand.3PubMed. Trigger toe in classical-ballet dancers A study tracking flexor hallucis longus injuries over 16 years found that dancers were more likely to develop partial longitudinal tears of the tendon, while non-dancers with the same tendon problems more often had isolated tenosynovitis without tearing.4PubMed. Flexor hallucis longus tendon injury in dancers and nondancers That difference likely reflects the sheer mechanical load that ballet places on the tendon.
Dancers are not the only people affected, though. The condition has been reported in manual laborers whose jobs require prolonged squatting, kneeling, or forceful push-off motions. One case report documented hallux saltans in an unskilled manual worker with no dance background, with the triggering occurring at an unusual anatomical site.1PubMed. Hallux saltans due to flexor hallucis longus entrapment at a previously unreported site in an unskilled manual laborer: a case report Athletes in sports that involve repetitive sprinting, jumping, or pushing off the forefoot are plausible candidates as well, though published data on trigger toe in these groups is sparser than for dancers.
Systemic conditions also raise your risk. Diabetes is linked to a cluster of musculoskeletal problems including tendon-sheath thickening conditions like trigger finger, and the same tissue changes can occur in the foot.5PubMed. Diabetes mellitus-related musculoskeletal disorders: Unveiling the cluster of diseases Rheumatoid arthritis and gout can also promote tendon-sheath inflammation in the toes. If you already have trigger finger or other tendon-sheath conditions in your hands, that history may be a signal that you are prone to similar problems elsewhere.
What Trigger Toe Feels Like
The hallmark symptom is a catching or locking sensation in the toe, usually the big toe, when you try to straighten it after bending. Sometimes you can actually feel or hear a click when the tendon finally pops past the narrowed point. In early stages, the toe might just feel stiff in the morning or after sitting for a while, and the catching may be intermittent. As the condition progresses, the locking can become more frequent and more difficult to release, sometimes requiring you to manually pull the toe straight with your hand.
Pain is common but variable. Some people notice it mostly at the base of the toe or along the inside of the ankle, where the tendon runs behind the bone. Others feel a deep ache in the arch of the foot. Swelling or tenderness along the tendon’s path is another typical sign, especially where it crosses behind the inner ankle. In dancers, the pain often appears during or immediately after relevé or en pointe positions and can be accompanied by a palpable snapping behind the ankle.
One thing that can confuse the picture is that trigger toe sometimes coexists with posterior ankle impingement. The flexor hallucis longus tendon passes through the same posterior ankle space that gets crowded when bone spurs or extra tissue compress the back of the ankle. If you have both problems at once, the pain and stiffness can feel diffuse, making it harder to pin down trigger toe as a distinct issue.
Getting a Diagnosis
Most trigger toe diagnoses start with a physical exam. A doctor or podiatrist will ask you to flex and extend the affected toe while they feel along the tendon for catching, clicking, or nodules. If the triggering is reproducible on exam, that is often enough to confirm the diagnosis clinically. The examiner may also check the posterior ankle region for snapping or tenderness, which helps locate where the tendon is getting stuck.
Imaging can add useful detail when the clinical picture is unclear. High-resolution ultrasound has proven capable of identifying the annular pulley structures in both the big toe and the lesser toes, which are the fibrous bands most relevant to triggering. A recent study showed that ultrasound could consistently visualize and measure the pulleys in toes one through four, though the fifth toe’s pulleys were harder to see reliably.6Skeletal Radiology. High-resolution ultrasound of the annular pulley system in the toes: sonographic anatomy and pathological cases Ultrasound can also show tendon thickening, fluid around the sheath, and the tendon actually catching in real time during movement. MRI is another option and is particularly good at detecting partial tendon tears, bone spurs, or other structural issues that might complicate the picture.
Treatment Without Surgery
The first line of treatment is almost always conservative, and many cases resolve without an operation. Rest and activity modification top the list. If you are a dancer, that might mean temporarily avoiding en pointe work. If you are a runner or manual laborer, reducing the specific movements that load the tendon is the starting point. Ice and anti-inflammatory medications can help manage the acute pain and swelling.
Physical therapy plays a central role. A therapist familiar with foot and ankle problems can guide you through stretches for the flexor hallucis longus tendon, eccentric strengthening exercises, and manual techniques to improve tendon gliding. For dancers with ankle and toe problems, a team approach involving both a physician and a knowledgeable physical therapist can often eliminate the need for surgery.7Journal of the American Academy of Orthopaedic Surgeons. Ankle Injuries in Dancers Splinting or taping to limit the toe’s range of motion can reduce irritation while the tendon heals.
Corticosteroid injections are sometimes used for trigger toe, as they are for trigger finger, to reduce inflammation inside the tendon sheath. An injection can provide relief that lasts weeks to months and may break the cycle of inflammation well enough that the triggering stops permanently. However, corticosteroid injections near tendons carry a small risk of weakening the tendon or surrounding tissue, so they are typically limited to one or two injections rather than repeated indefinitely.
Footwear changes can also help. Shoes with rigid soles that limit toe flexion reduce the demand on the flexor tendon. For some people, a stiff-soled shoe insert or a rocker-bottom shoe takes enough stress off the toe to allow recovery. Custom orthotics may be recommended if an underlying foot structure issue, like excessive pronation, is contributing to the problem.
When Surgery Becomes Necessary
If conservative measures fail after several months, or if the triggering is severe enough that the toe locks and cannot be released without manual intervention, surgery becomes a reasonable option. The goal of surgery is to release the constricted portion of the tendon sheath or address the structural problem causing the catching.
The traditional approach involves an open incision to reach the tendon and release the tight tunnel or remove adhesions. This has been effective but requires a larger wound and more extensive tissue work, especially when the release needs to happen near the posterior ankle where blood vessels and nerves are close by.8Arthroscopy Techniques. Endoscopic Release of the Flexor Hallucis Longus Tendon at Posterior Ankle for Management of Checkrein Deformity of the Great Toe, Second Toe, and Third Toe
Endoscopic techniques have emerged as an alternative. These use small incisions and a camera to perform the release with less tissue disruption. In one described technique, the flexor hallucis longus tendon is cut at a specific point above where it branches to serve multiple toes. Because of the anatomical connections between the big toe’s tendon and the tendons of the second and third toes, releasing the tendon at this location can correct triggering or deformity in all three toes at once. The advantages of endoscopic release include smaller wounds, less soft tissue disruption, and the ability to begin moving the ankle and toes immediately after surgery.8Arthroscopy Techniques.

What Recovery Looks Like
Recovery timelines depend on the type of procedure and the demands you need to return to. For dancers who underwent open surgery for flexor hallucis longus tendinopathy at the posterior ankle, roughly nine out of ten reported a “better” or “much better” outcome after surgery, with only minor, transient complications.9Journal of Dance Medicine & Science. Posterior Ankle Impingement Syndrome and M. Flexor Hallucis Longus Tendinopathy in Dancers Results of Open Surgery The approach used can affect the timeline. In that same study, patients who had a lateral surgical approach were discharged from follow-up earlier (a median of about four months) compared to those who had a medial approach (about six months), though the final outcomes were similar for both groups.
After endoscopic release, early mobilization is one of the selling points. Patients are typically encouraged to move the ankle and toes right away, which helps prevent stiffness and may speed the return to normal activity. For non-athletes, returning to regular shoes and daily walking within a few weeks is a common trajectory. For dancers and competitive athletes, the road back to full performance is longer and usually involves a structured rehabilitation program with a physical therapist who understands the specific demands of the activity.
One consideration after tendon release surgery is that cutting the flexor hallucis longus tendon does reduce push-off strength to some degree, since you are sacrificing part of the mechanism that flexes the big toe. For most people, this trade-off is well worth making to eliminate the locking and pain. For elite dancers, though, even small changes in toe flexion strength can affect performance, which is one reason conservative treatment gets a long trial before surgery is recommended in that population.
Trigger Toe in the Lesser Toes
While most discussions of trigger toe focus on the big toe, the smaller toes can develop triggering too. Researchers have identified a pulley system in the lesser toes that is analogous to the pulley system in the fingers. In a study that dissected 50 cadaver toes, investigators found a series of transverse to obliquely oriented fibrous bands running from the metatarsal heads to the distal phalanges, essentially the same kind of retaining tunnels that can cause triggering in the hand.10PubMed. Triggering of the lesser toes at a previously undescribed distal pulley system The same study described five patients who presented with metatarsal pain and triggering of their lesser toes, confirming that the condition is not limited to the big toe.
Lesser-toe triggering is rarer than big-toe triggering, and it can be trickier to diagnose because the symptoms overlap with other forefoot problems like metatarsalgia or hammertoe. If a smaller toe catches or locks during bending, particularly at the ball of the foot, it is worth mentioning to your doctor specifically, since trigger toe is not always the first thing clinicians consider in the lesser toes.
How Trigger Toe Differs from Trigger Finger
Despite the shared mechanism, trigger toe and trigger finger are not identical conditions. The flexor hallucis longus tendon is much longer than any finger flexor, running from the calf through the ankle and under the foot before reaching the toe. That longer path means there are more potential sites where catching can occur. In the hand, trigger finger almost always happens at the A1 pulley at the base of the finger. In the foot, the catching can happen at the posterior ankle tunnel, at the fibro-osseous tunnel under the sustentaculum tali, at the “master knot of Henry” where the big-toe tendon crosses beneath another tendon in the midfoot, or at the toe-level pulleys.
The difference in anatomy also affects treatment. Releasing a trigger finger at the A1 pulley is a minor procedure with a short recovery. Releasing a toe tendon at the posterior ankle is more involved and carries considerations about nearby nerves and blood vessels. The weight-bearing demands on the foot add another layer of complexity to rehabilitation that the hand does not share.
Trigger finger is also far more common in the general population. It frequently shows up in people over 50, in women more than men, and in anyone with diabetes or inflammatory conditions. Trigger toe, by contrast, clusters more heavily in specific activity groups. If you have trigger finger and notice similar symptoms in your foot, the conditions may share underlying risk factors, but the toe problem requires its own evaluation.
Toe Conditions in Children
True trigger toe is rare in children, but parents sometimes worry about toe deformities that look vaguely similar. Congenital curly toes, a condition where one or more toes curl under or to the side, is the most common pediatric toe concern. It is not the same thing as trigger toe, since there is no catching or locking mechanism involved. Instead, curly toes result from tightness in the toe’s flexor tendons that pulls the toe into a bent and rotated position.
The fourth and fifth toes are most commonly affected. A systematic review found that the fourth toe accounts for about 44% of cases and the fifth toe about 25%.11PubMed Central. Congenital Curly Toes in the Pediatric Population: A Management Algorithm and Systematic Review For mild cases, observation or taping is the usual approach, and many children’s toes straighten on their own as they grow. More severe curly toes that cause pain or shoe-fitting problems may require a minor surgical procedure to release or transfer the tight tendon. The review found that surgical treatment produced more favorable and lasting results for moderate to severe cases compared to conservative approaches alone.11PubMed Central. Congenital Curly Toes in the Pediatric Population: A Management Algorithm and Systematic Review
If a child’s toe is genuinely locking or snapping rather than simply curling, that warrants a closer look by a pediatric orthopedist or podiatrist, since true triggering in a child’s toe could indicate an unusual anatomical variant or an acquired tendon-sheath problem that is not typical for their age group.
When a Snapping Toe Is Not Trigger Toe
Not every click or snap in your toes means you have trigger toe. A few other conditions can produce similar sensations. A subluxing peroneal tendon, for example, can cause a snapping feeling around the outside of the ankle and foot. Intermetatarsal bursitis or a Morton’s neuroma can create sharp, clicking sensations in the ball of the foot that some people describe as their toe “catching.” Loose bodies in a toe joint from old injuries or arthritis can produce mechanical clicking too.
The distinguishing feature of true trigger toe is that the toe gets stuck in a flexed position and then releases with a palpable pop, just like a trigger finger. If the snapping you feel is not accompanied by the toe actually locking in a bent position, the problem is more likely one of these other conditions. A physical exam that specifically tests for triggering, with the examiner palpating the tendon while you move the toe, is the most reliable way to sort it out.
Hammertoe and claw toe deformities can also be confused with trigger toe because they produce fixed or semi-fixed flexion of the toes. The difference is that hammertoe is a structural deformity of the toe joint itself, while trigger toe involves a normally shaped joint whose movement is impeded by a tendon problem. Hammertoe does not produce the catching-and-releasing cycle. The two conditions can coexist, though, especially in older adults or people with long-standing diabetes, making accurate diagnosis especially important for choosing the right treatment.
