Hammer toe is one of the most common foot deformities — affecting an estimated 18% of US adults, rising to as many as half of older adults, and five times more common in women than men. Most people can manage it without surgery, particularly when it is caught in the early, flexible stage. Here is a complete guide to what hammer toe is, what causes it, how to recognize it, and the full range of treatments from taping and splints to surgical options.

What Is a Hammer Toe?
A hammer toe is a deformity of the proximal interphalangeal (PIP) joint — the middle joint of a toe. In a hammer toe, this joint bends upward (buckles), while the tip of the toe bends downward, creating a shape that resembles a hammer. The second toe is most commonly affected, but the third and fourth toes can also develop the deformity. It can also occur in the fifth (pinky) toe, though less frequently.
The Merck Manual defines hammer toe as resulting from ‘an imbalance of the digital extensor and flexor tendons that typically causes a contracture at the proximal interphalangeal joint.’ The imbalance pulls the joint into a bent position — and over time, if left untreated, this bent position becomes permanent as the surrounding tissues tighten and the joint becomes rigid.
Flexible vs Rigid Hammer Toe: The Critical Distinction
The most clinically important distinction in hammer toe is whether the deformity is flexible or rigid:
| Flexible Hammer Toe | Rigid Hammer Toe | |
| Stage | Early | Advanced |
| Joint movement | Toe can still be straightened by passive manipulation | Toe is fixed in bent position; cannot be manually straightened |
| Treatment options | Full range: taping, splinting, exercises, shoes | More limited: primarily surgical; conservative measures only manage symptoms |
| Urgency | Address early to prevent progression | See a podiatrist — surgical evaluation may be necessary |
Catching hammer toe in the flexible stage is significant because conservative treatments — the right shoes, taping, splinting, and exercises — can slow or stop the progression and provide meaningful symptom relief. Once the deformity becomes rigid, those same treatments can only manage the symptoms; they cannot correct the structural problem, which may require surgery.
Hammer Toe Symptoms
Hammer toe symptoms range from cosmetic concerns to genuinely painful and mobility-limiting:
- Visible bend at the middle joint of the affected toe — the characteristic ‘hammer’ or ‘claw’ shape with the middle joint raised upward
- Corn or callus on top of the bent joint — caused by the raised joint rubbing against the inside of the shoe; this is often the first painful symptom that brings people to a podiatrist
- Callus on the tip of the toe — from the toe tip pressing down against the floor or shoe due to the joint’s raised position
- Pain when wearing shoes — the bent joint contacts the shoe’s toe box, causing friction, pressure, and pain during walking
- Difficulty finding comfortable footwear — most standard shoes compress the toe box, aggravating the deformity
- Redness and inflammation around the affected joint
- In advanced cases: open sores or ulceration at friction points — particularly a concern for people with diabetes or poor circulation
Hammer toe of the pinky (fifth) toe presents similarly but the friction point is typically the outer side of the toe rubbing against the inside of the shoe rather than the top of a middle toe. The same progression from flexible to rigid occurs, and the same treatments apply.
What Causes Hammer Toe?
Hammer toe has both structural and lifestyle causes:
Tendon Imbalance
The primary underlying cause is an imbalance between the extensor tendons (which straighten the toe) and flexor tendons (which bend it). Per the Merck Manual, this imbalance ‘may originate as an injury or is due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures.’ When one set of tendons pulls harder than the other over time, the joint gradually bends into the hammer position.
Ill-Fitting Shoes
The most common lifestyle trigger is shoes with a tight or pointed toe box — shoes that compress the toes together and force them into a bent position for hours at a time. High-heeled shoes are a major contributing factor: they shift body weight forward onto the ball of the foot, increasing pressure on the toes and forcing them against the toe box. Years of wearing tight, narrow, or high-heeled shoes can trigger or accelerate hammer toe development in people with a predisposition.
Bunion (Hallux Valgus)
A bunion (hallux valgus) — a misalignment of the big toe that pushes it toward the smaller toes — can cause hammer toe in adjacent toes. As the big toe crowds the second toe, the second toe has nowhere to go except upward, initiating the hammer toe deformity.
Medical Conditions
Rheumatoid arthritis can cause hammer toe through joint inflammation and erosion that disrupts the tendon balance. Neurological conditions including Charcot-Marie-Tooth disease (a hereditary neuropathy affecting muscle control in the feet and legs) can also cause hammer toe through the progressive muscle imbalance they create.
How to Fix Hammer Toes with Tape
Taping is one of the most accessible first-line treatments for flexible hammer toe. It works by physically holding the toe in a corrected position, reducing pressure on the bent joint, and providing temporary symptom relief. Taping does not permanently straighten the toe — it is a management and symptom-relief tool, not a cure.
Kaiser Permanente’s recommended taping method:
- Start with the toe next to the hammer toe (the toe on either side — typically the big toe or the toe adjacent to it)
- Wrap the tape under that neighboring toe, across and over the hammer toe, and then under the next toe on the other side
- The tape gently pulls the hammer toe downward into a more normal position, reducing the upward bend at the PIP joint
- Use medical-grade tape or Kinesiology tape (KT tape) — these are more skin-friendly and breathable than standard adhesive tape
- Check skin condition regularly — tape can cause skin irritation or blistering if left too long without changing
An NIH-published case study (2021) found that kinesiology taping ‘seems to be a symptomatic form of treatment of the effects of lesser toes deformity’ and concluded it is ‘a good alternative for patients who do not want or cannot undergo surgery.’ The taping reduces pain and friction by holding the toe in a corrected position, even if it does not alter the underlying joint structure permanently.
Hammer Toe Splints and Correctors
Hammer toe splints, toe slings, and correctors perform a similar function to taping — they hold the toe in a corrected position passively — but are reusable, more consistent in their positioning, and more convenient for daily use.
The main types:
- Toe caps/toe sleeves: Soft silicone or foam caps that slip over the bent toe, cushioning the dorsal surface from shoe contact and gently positioning the toe
- Toe crests: Pads that sit under the toes, helping to lift the tip of the toe and reduce the bend at the middle joint
- Toe slings/straighteners: Loops or straps that wrap around the toe and pull it toward a more extended position
- Rigid toe splints: Harder devices that hold the toe in a fixed position; more effective for stabilization but less comfortable for all-day wear
These OTC correctors are most effective in the flexible stage — when the joint can still be passively moved toward a normal position. Once the deformity is rigid, splints can manage symptoms (reducing corn formation, reducing shoe friction) but cannot correct the structural deformity. They do not need a prescription and are widely available at pharmacies, podiatry clinics, and online.
Shoes for Hammer Toes
Footwear is both a cause and a treatment for hammer toe. The right shoes can dramatically reduce pain and slow the deformity’s progression; the wrong shoes accelerate it and make every step painful.
What to look for:
- Wide toe box: Enough width in the front of the shoe for toes to lie flat and spread naturally without compression. This is the single most important feature
- Adequate depth in the toe box: Vertical space for the raised hammer toe joint to sit without rubbing against the shoe’s roof
- Low heel: Minimizes forward weight shift onto the toes; flats or heels under 1 inch are best
- Soft, flexible upper material: Reduces pressure on the bent joint
- Removable insole: Allows custom orthotics if prescribed by a podiatrist
Brands commonly recommended for hammer toe and toe deformities:
- Altra: Zero-drop sole and naturally wide, foot-shaped toe box — one of the most toe-friendly designs available
- New Balance: Offers genuine wide (D, 2E, 4E) widths across multiple models
- Hoka: Wide toe box on most models; generous room through the forefoot
- Brooks: Wide widths available; supportive without compressing the toes
- Orthofeet: Designed specifically for foot conditions including hammer toe, bunions, and plantar fasciitis; extra depth and width
Shoes to avoid: pointed toe box (any style), high heels over 1 inch, narrow athletic shoes, and any shoe that causes the toe to compress against the front or top of the shoe.
Early Stage Hammer Toe: Acting Before It Becomes Rigid
Early-stage hammer toe is the optimal time to intervene. In the flexible stage, the joint can still be straightened manually — meaning conservative treatments have the best chance of slowing or stopping the progression. The typical progression without intervention:
- Stage 1 — Flexible: Toe bends at PIP joint but can be straightened by hand; mild symptoms; responds well to taping, splinting, and shoe changes
- Stage 2 — Semi-rigid: Toe bends more significantly; passive straightening is possible but meets resistance; moderate symptoms; conservative treatments still helpful but less effective
- Stage 3 — Rigid: Toe is fixed in the bent position; cannot be manually straightened; significant symptoms including corns, pain, and difficulty with footwear; surgery is often necessary for meaningful correction
If you notice your toe beginning to bend, the most effective action is changing footwear immediately and beginning a splinting and stretching routine. Most people delay seeking attention until the deformity becomes symptomatic and more advanced — earlier intervention consistently leads to better outcomes.
Exercises for Hammer Toe
Physical therapy exercises maintain flexibility in the toe joints and can slow the progression in the flexible stage. Kaiser Permanente recommends:
- Passive toe stretching: Gently pull on the bent toe to stretch the bent joint in the opposite direction. If the joint bends up, gently stretch it downward. Hold for several seconds. Feel a long, slow, gentle pull. Work on one joint at a time. Repeat several times morning and evening
- Towel scrunches: Place a towel flat under your foot. Use your toes to crumple it toward you. This exercises the intrinsic foot muscles that help maintain normal toe position
- Marble pickups: Place marbles on the floor and use your toes to pick them up and drop them into a cup. Strengthens the small muscles of the foot
- Toe spreads: Spread your toes as wide as possible, hold for 5-10 seconds, release. Repeat 10 times. Maintains range of motion
These exercises are most effective as a prevention and early-stage management tool. They cannot reverse a rigid deformity but can maintain function and reduce symptoms.
When Is Surgery Needed for Hammer Toe?
Surgery is typically considered when conservative treatments have not provided adequate relief, the toe is rigid and no longer responds to passive correction, or walking has become significantly painful. Per the Merck Manual: ‘surgical intervention may be considered for refractory symptoms.’
The most common surgical procedure is resection arthroplasty — removal of a small portion of bone at the contracted joint to allow the toe to straighten. A wire or tape holds the toe in the corrected position for 3 to 6 weeks during healing. Most procedures are outpatient. A 2000 study of 63 patients (118 toes) found that resection arthroplasty provided pain relief for 92% of patients, with only 5% experiencing minor complications, at an average follow-up of 61 months.
Other surgical options include tendon release (cutting tight tendons), joint fusion (arthrodesis — permanently joining the bones), and in severe cases, joint implants or stabilization with pins. Your podiatrist or orthopedic surgeon will recommend the most appropriate procedure based on the severity of your deformity and other factors.
Frequently Asked Questions
What is a hammer toe?
A hammer toe is a deformity where the middle joint of a toe (the proximal interphalangeal joint) bends upward in a buckled position, while the tip bends downward. It results from an imbalance between the extensor and flexor tendons. The second toe is most commonly affected. It affects approximately 18% of US adults, rising to 50% in older adults, and is five times more common in women.
What does a hammer toe look like?
A hammer toe appears as a raised bend at the middle joint of the toe, with the toe tip pointing downward — resembling the head of a hammer. There is often a corn or callus on top of the raised joint where it rubs against the shoe. In early stages the bend is mild; in advanced stages the toe is clearly and significantly bent.
How do you fix hammer toes with tape?
Wrap tape under the neighboring toe, over the hammer toe, and under the next toe on the other side — this gently pulls the hammer toe downward toward a normal position. Kinesiology tape or medical tape works best. This method reduces friction and provides symptom relief but does not permanently straighten the toe.
Do hammer toe splints work?
Toe splints and correctors work best in the flexible (early) stage of hammer toe, when the joint can still be passively moved toward a normal position. They reduce corns, decrease shoe friction, and hold the toe in a better position during daily activity. They do not correct a rigid hammer toe structurally but can manage symptoms effectively.
What shoes are best for hammer toes?
The most important feature is a wide toe box — enough room for the toes to lie flat without compression. Recommended brands include Altra (naturally wide toe box), New Balance (available in genuine wide widths), Hoka, Brooks, and Orthofeet (specifically designed for foot conditions). Avoid pointed toe boxes and high heels.
What is hammer toe of the pinky toe?
Hammer toe can affect the fifth (pinky) toe, though it is less common than in the second, third, or fourth toes. The same mechanisms apply — tendon imbalance, tight shoes, or secondary effects from adjacent deformities. The friction point is typically the outer side of the toe rubbing against the shoe. Treatment is the same as for other hammer toes: wide toe box shoes, taping, splinting, and surgery if conservative measures fail.
Final Thoughts
Hammer toe is a common, manageable condition — but one that becomes progressively harder to treat without surgery as it advances from flexible to rigid. The clear message from the clinical evidence is to act early: switch to wide toe box shoes as soon as any bending appears, begin taping and splinting, do the strengthening exercises, and see a podiatrist if symptoms persist or worsen. The conservative treatments available — taping, splinting, footwear changes, orthotics, and exercises — are genuinely effective in the flexible stage and carry no risks. Surgery, when needed, has a strong success rate, but the best outcome remains avoiding the need for it through early intervention.
