Frequently Asked Questions
When should I see a podiatrist?
See a podiatrist if: foot or ankle pain has lasted more than 2–4 weeks without improvement, you’re changing your gait to avoid pain, you have an open wound or sore that isn’t healing, you notice nail discoloration or thickening, you have diabetes and any foot concern, or pain is severe enough to wake you at night. Most foot conditions are easier and cheaper to treat early — what starts as a minor issue can become a surgical problem with months of delay.
What is the difference between a podiatrist and an orthopedic surgeon?
Podiatrists (DPM — Doctor of Podiatric Medicine) specialize exclusively in the foot, ankle, and lower leg. Orthopedic surgeons (MD/DO) have broader musculoskeletal training but variable foot/ankle subspecialization. For foot and ankle-specific problems, a podiatrist often has more focused training and experience. For injuries involving the leg above the ankle, complex pediatric cases, or multi-level reconstruction, orthopedic consultation may be appropriate. We frequently co-manage patients with orthopedic colleagues.
How do I know if my foot pain is serious?
Signs that warrant same-day or next-day evaluation: severe pain that appeared suddenly without clear cause, swelling, redness, and warmth that appeared suddenly (possible gout, infection, or Charcot fracture), an open wound that looks infected (redness spreading, pus, warmth), inability to bear weight, or any foot problem in a diabetic patient. Pain that’s been present for weeks and is stable is important but not an emergency — schedule within 1–2 weeks.
Can foot problems cause back and knee pain?
Yes — this is a kinetic chain effect. Abnormal foot mechanics (overpronation, supination, leg length discrepancy) cause compensatory changes in knee, hip, and lumbar alignment. Roughly 30% of patients presenting to our clinic with knee pain have a treatable foot-level biomechanical cause. Correcting foot mechanics with orthotics or appropriate footwear often provides significant knee and back relief. If you have chronic knee or back pain and haven’t had your foot mechanics evaluated, it’s worth a consult.
Are orthotics worth it?
For the right conditions, yes — custom orthotics are among the most cost-effective interventions in podiatry. They’re most effective for: plantar fasciitis, flat feet with secondary knee/back pain, leg length discrepancy, metatarsalgia, posterior tibial tendon dysfunction, and diabetic foot pressure management. Quality OTC orthotics ($35–60) resolve symptoms for 60% of patients with mild-to-moderate conditions. Custom orthotics are appropriate when OTC options have failed or when the biomechanical problem is complex. We cast custom orthotics in-office.
How do I choose the right running shoes?
Start with your foot type (flat, neutral, high arch) and running pattern (overpronator, neutral, supinator). Flat feet and overpronators do best in stability or motion-control shoes. Neutral feet do well in neutral-cushioned shoes. High arches need maximum cushioning with flexible soles. Always buy running shoes at the end of the day (foot swelling peaks then), get properly fitted by a specialist, and replace every 300–500 miles. If you’ve been injured repeatedly, a gait analysis can identify the mechanical flaw driving your injury pattern.
What is the difference between a sprain and a fracture?
A sprain is a ligament injury (the tissue connecting bones); a fracture is a break in the bone itself. Both can occur with the same trauma (ankle roll, fall). The old test — ‘if you can walk, it’s not broken’ — is wrong; many fractures are initially weight-bearable. Key differences: a fracture typically produces localized bone tenderness along the bone itself, while a sprain is tender over the ligament. X-ray is the standard to differentiate. High-grade sprains without proper treatment can be as disabling as fractures.
How do I prevent foot and ankle injuries?
The four most impactful prevention strategies: (1) Supportive, appropriately fitted footwear for your foot type and activity. (2) Gradual activity progression — the 10% rule (never increase weekly mileage or intensity by more than 10%). (3) Regular calf and ankle mobility work. (4) Strengthening the posterior tibial tendon, peroneals, and intrinsic foot muscles. Most overuse injuries are preventable; most acute injuries are not — but ankle sprain recurrence (60–70% without rehab) is prevented by balance and proprioception training.

A clicking or popping sound from the foot is one of those symptoms that patients often describe with a mix of fascination and anxiety — fascinated because it’s odd to hear your foot make sounds, anxious because they worry something must be broken or wearing out. The good news: the vast majority of foot clicking is completely benign and requires no treatment. The nuance: a subset of clicking patterns — particularly those associated with pain, instability, or progression — do indicate real pathology that benefits from early identification.
Why Feet Click: The Main Mechanisms
There are three primary mechanisms that produce clicking sounds in the foot and ankle. Understanding which one is generating your click — or which combination — is the key to determining whether anything needs to be done about it.
1. Cavitation — the release of dissolved gas from synovial fluid in a joint capsule. This produces the familiar “crack” associated with knuckle-cracking and is the same mechanism in foot and ankle joints. It requires the joint capsule to be temporarily stretched beyond its resting position, which is why it often only clicks in a specific end-range position. After cavitation, the gas redissolves and the joint won’t click again for 15–30 minutes. This mechanism is completely harmless.
2. Tendon snapping — a tendon flicking over a bony prominence during specific joint movements. The peroneal tendons (outer ankle), posterior tibial tendon (inner ankle), and flexor hallucis longus tendon (big toe) are the most common sources. The snap is often palpable as well as audible — you can feel the tendon flick under your fingers. This is usually benign when painless but can indicate tendon instability in a minority of cases.
3. Ligament or retinaculum flicking — a ligamentous or fascial structure briefly catches on a bony edge during movement. Less common than the above two, but occurs at the subtalar and calcaneocuboid joints in certain foot types. Often position-dependent and reproducible.
Joint Cavitation (Harmless Popping)
Joint cavitation is the most common cause of foot clicking and requires no treatment. The pop occurs when the joint capsule is momentarily distracted — typically at end-range dorsiflexion, plantarflexion, or inversion — allowing dissolved nitrogen gas to form a gas bubble in the synovial fluid. The characteristic “pop” is the bubble collapsing as fluid rushes back in.
Despite decades of concern that knuckle-cracking causes arthritis, long-term studies have consistently shown no relationship between joint cavitation and osteoarthritis. The same applies to foot and ankle joints. If your foot pops occasionally during stretching or specific movements without pain, this is a benign variant of normal joint mechanics that does not need intervention.
Cavitation clicks are typically: intermittent (not every step), audible and sometimes felt, reproducible only in specific positions, non-painful, not associated with instability, and followed by a refractory period before they can occur again. If your clicking fits all these criteria, no evaluation is needed.
Tendon Snapping and Subluxation
Tendon snapping occurs when a tendon slips off or over a bony prominence during specific joint movements. Unlike cavitation, snapping tendons typically click with every repetition of the provoking movement (every step, every ankle circle) rather than intermittently. The snap may be palpable — you can feel the tendon move under your skin.
Peroneal tendon snapping (outer ankle): The peroneal tendons (peroneus longus and brevis) run behind the lateral malleolus (outer ankle bone) in a groove held in place by the superior peroneal retinaculum. In some patients — particularly after ankle sprains that tear the retinaculum — one or both tendons snap out of the groove with ankle movement, producing a visible and audible pop at the outer ankle. This is called peroneal tendon subluxation and, while often painless initially, can lead to tendon tears and ankle instability over time. It warrants evaluation.
Posterior tibial tendon snapping (inner ankle): The posterior tibial tendon passes behind the medial malleolus (inner ankle bone). Snapping here is felt as a click or catch at the inner ankle and is sometimes associated with flatfoot deformity progression. Less common than peroneal snapping but significant when present.
Flexor hallucis longus (FHL) snapping (big toe, back of ankle): The FHL tendon runs from the back of the ankle through a tunnel in the plantar foot to insert on the distal big toe. It can snap within its tunnel — a condition called “trigger toe” or FHL tenosynovitis — producing a click at the back of the ankle or under the big toe with toe flexion and extension. Common in ballet dancers and athletes who repeatedly plantarflex the foot against resistance.
| Click Source | Location | Provoking Movement | Painful? | Clinical Concern |
|---|---|---|---|---|
| Joint cavitation | Any joint | End-range position | No | None — benign |
| Peroneal tendon subluxation | Outer ankle | Ankle eversion/circumduction | Often not initially | Yes — can progress |
| Posterior tibial tendon | Inner ankle | Foot inversion | Sometimes | Yes — flatfoot association |
| FHL trigger toe | Big toe, back ankle | Toe flexion/extension | Often | Yes — dancers especially |
| Subtalar joint | Under ankle | Inversion/eversion | Variable | Low — usually benign |
| MTP joint cavitation | Toe joints | Toe extension | No | None — benign |
What the Click Location Tells You
In our clinic, the first question we ask when a patient reports foot clicking is: exactly where is the click happening? This single piece of information dramatically narrows the differential and guides the examination.
Outer ankle: Strongly suggests peroneal tendon pathology. We assess for peroneal tendon subluxation by having the patient actively evert the foot against resistance while we observe and palpate behind the lateral malleolus. A visible or palpable snap confirms the diagnosis. We may order ultrasound or MRI to assess the retinaculum integrity and rule out tendon tears.
Inner ankle: Suggests posterior tibial tendon or spring ligament pathology. We assess for flatfoot deformity, ask about progressive arch collapse, and evaluate single-leg heel raise capacity. Inability to perform a single-leg heel raise with clicking at the inner ankle suggests significant PTT dysfunction.
Back of the ankle / heel: FHL tendon pathology. We assess for clicking with toe flexion and extension in a specific ankle position. Common in runners and dancers. MRI is the gold standard for FHL tenosynovitis assessment.
Ball of the foot: Morton’s neuroma can occasionally produce a “Mulder’s click” — a palpable click when the forefoot is compressed laterally — along with sharp or burning pain in the toe web space. This is a diagnostic maneuver rather than a spontaneous symptom, but some patients do report a clicking sensation in the forefoot with specific footwear.
Toe joints: Almost always benign cavitation, particularly at the metatarsophalangeal joints when toes are extended. Very commonly experienced and clinically insignificant unless accompanied by pain or swelling that suggests arthritis or turf toe injury.
Painful Clicking: When to Worry
Painless clicking in the foot is almost never a clinical concern. Painful clicking is a different matter entirely — pain indicates that the clicking is producing tissue stress that exceeds normal tolerance. In our clinic, painful foot clicking always warrants thorough examination and usually imaging because it changes the differential significantly.
The most important clinical associations with painful foot clicking are: peroneal tendon subluxation with lateral ankle pain (particularly with pushing off or running), FHL tenosynovitis with big toe pain during push-off (especially in dancers), Morton’s neuroma with sharp burning pain in the toe web space provoked by shoe compression, and early ankle or MTP joint arthritis where clicking is accompanied by morning stiffness and progressive pain.
Ankle and Heel Clicking Specifically
Ankle clicking deserves specific attention because it can represent several distinct pathologies with meaningfully different prognoses. After an ankle sprain, new clicking at the outer ankle should always be evaluated — the same force that tears the lateral ligaments can also tear the superior peroneal retinaculum, releasing the peroneal tendons from their groove and creating the conditions for peroneal subluxation. Patients who develop new outer-ankle clicking after a sprain and don’t have it assessed risk developing chronic peroneal tendon tears.
Heel clicking specifically — a snap or pop at the back of the heel with walking — often represents the Achilles tendon or FHL tendon and is worth evaluation in any patient with concurrent heel or ankle pain. Painless heel clicking without any history of Achilles symptoms is usually benign but worth mentioning at your next routine podiatric visit.
Treatment for Clicking That Causes Problems
Treatment for symptomatic foot clicking targets the specific underlying mechanism rather than the clicking sound itself. Here’s how we approach the most common treatable causes:
Peroneal tendon subluxation: Conservative management with a lateral ankle brace (to prevent the eversion movement that provokes snapping), physical therapy to strengthen the peroneal muscles and improve retinaculum healing, and activity modification. If conservative treatment fails after 3–6 months, surgical retinaculum repair is highly effective and returns most patients to full athletic activity.
FHL tenosynovitis (trigger toe): Rest from provoking activities, a period of anti-inflammatory treatment (oral or injection), and physical therapy focusing on FHL flexibility and eccentric loading. Most cases resolve with conservative management. Dancers may need activity modification for 6–12 weeks.
Morton’s neuroma (Mulder’s click): Wider toe box shoes, metatarsal pad placement just proximal to the metatarsal heads, corticosteroid injections for acute flares, and alcohol sclerosing injections for recalcitrant cases. Surgical neurectomy for cases unresponsive to conservative treatment.

PowerStep Pinnacle Insoles
For patients with foot or ankle clicking related to biomechanical abnormalities — flat feet causing medial ankle tendon stress, or cavus feet concentrating lateral ankle load — PowerStep Pinnacle provides the arch support and heel control that reduces abnormal tendon excursion during gait. By normalizing the mechanical environment during walking and running, these insoles reduce the pronation and supination extremes that provoke tendon snapping in susceptible patients. The deep heel cup specifically improves hindfoot stability, which is beneficial for both peroneal and posterior tibial tendon pathology.
Best for: Foot clicking associated with flat feet or excessive pronation; inner ankle clicking with arch pain; general foot biomechanical support during recovery from tendon pathology.
Not Ideal For: Acute tendon subluxation requiring immobilization — a brace or boot takes priority. High-arched feet requiring more aggressive lateral posting. Complex tendon pathology requiring custom orthotic prescription.
Doctor Hoy’s Natural Pain Relief Gel
When foot or ankle clicking is accompanied by pain and local soft tissue inflammation — particularly in cases of FHL tenosynovitis, peroneal tendinopathy, or symptomatic joint clicking — Doctor Hoy’s arnica and camphor gel provides targeted topical anti-inflammatory relief. Apply to the area of discomfort (posterior ankle, outer ankle, or forefoot) 2–3 times daily. The natural arnica component reduces soft tissue inflammation associated with repetitive tendon microtrauma, while camphor and menthol provide immediate topical analgesia. Suitable for ongoing use during conservative management of tendon clicking.
Best for: Painful tendon snapping sites; peri-tendinous inflammation during conservative management; post-injection soreness.
Not Ideal For: Painless clicking — no treatment is needed. Open or abraded skin. As a replacement for physical therapy or mechanical treatment of the underlying tendon pathology.
Warning Signs Requiring Evaluation
⚠ Foot Clicking That Needs Professional Evaluation
- Clicking at the outer ankle after a sprain — new clicking post-sprain suggests peroneal retinaculum tear and tendon subluxation; evaluate before the condition progresses to tendon tears
- Any clicking accompanied by pain — pain changes the differential from benign cavitation to pathological tendon/joint processes
- Clicking with instability — feeling like the ankle “gives way” with the click suggests ligamentous or retinacular insufficiency
- Progressive clicking becoming more frequent or louder — progression suggests worsening mechanical pathology rather than benign variant anatomy
- Clicking with swelling at the clicking site — inflammatory process (tenosynovitis, joint effusion, arthritis) rather than benign snapping
- Clicking in a dancer, runner, or athlete with performance limitation — FHL and peroneal pathology in high-demand athletes needs early intervention to prevent career-affecting progression
The Most Common Mistake
The most common mistake we see is patients (and sometimes primary care physicians) dismissing ankle clicking after a sprain as “normal healing sounds.” After a lateral ankle sprain, new clicking at the outer ankle is peroneal tendon subluxation until proven otherwise — not a sign that the ankle is healing. Missing this diagnosis means the peroneal tendons continue to sublux with every step, gradually tearing against the posterior fibula edge, and what started as a conservative treatment case becomes a surgical one.
The fix: any patient who develops new outer ankle clicking after an ankle sprain should have it specifically evaluated — not just the ligamentous sprain, but the peroneal tendon behavior behind the lateral malleolus. We assess this routinely in all post-ankle-sprain evaluations at Balance Foot & Ankle.
In-Office Evaluation at Balance Foot & Ankle
At Balance Foot & Ankle, we evaluate foot clicking with a systematic clinical examination that identifies the specific mechanism — joint cavitation, tendon snapping, or ligament flicking — and determines whether pathological tissue is involved. Dr. Tom Biernacki performs dynamic examination of the tendons under active and passive movement, palpates the tendon grooves, and orders ultrasound or MRI when tendon pathology is suspected. Most painless clicking can be reassured without imaging.

Frequently Asked Questions
Is it bad if my foot clicks when I walk?
Usually no. Most foot clicking during normal walking is benign tendon snapping or joint cavitation. The key distinguishing factor is pain: painless clicking almost never requires treatment. Clicking accompanied by pain, swelling, or a feeling of instability does warrant evaluation — particularly at the ankle after a sprain history.
Why does my ankle click every time I rotate it?
A consistent click with every ankle rotation — particularly in the same direction — is most likely a tendon snapping over a bony prominence rather than joint cavitation (which can’t occur with every repetition). The peroneal tendons (outer ankle) are the most common source. If it’s painless, it typically requires no treatment. If painful, or if you’ve had a previous ankle sprain, have it evaluated for peroneal tendon subluxation.
Does a clicking ankle mean arthritis?
Not necessarily. Joint clicking (crepitus) is associated with osteoarthritis when it occurs alongside joint stiffness, progressive pain, and morning stiffness lasting more than 30 minutes. Isolated clicking without pain or restriction is not diagnostic of arthritis. If you have clicking plus morning stiffness, joint swelling, or pain that worsens with activity over weeks to months, evaluation is warranted.
Can foot clicking be stopped?
Painless cavitation clicking cannot be reliably stopped and doesn’t need to be. Tendon snapping clicks can sometimes be reduced by addressing the biomechanical factors that promote abnormal tendon excursion — correcting foot mechanics with insoles, strengthening the muscles surrounding the snapping tendon, or in more severe cases, surgical retinaculum repair to restore the tendon to its normal groove.
When should I see a podiatrist for foot clicking?
See a podiatrist if clicking is: accompanied by pain at the click site; associated with a feeling of ankle instability or giving way; new after an ankle sprain; progressive and becoming more frequent; occurring at the outer ankle in any runner or athlete; or if the clicking worsens with activity while pain is also increasing. Painless clicking without any of these features can be monitored and mentioned at your next routine visit.
