Toes twist when the muscles, tendons, and ligaments that hold them straight fall out of balance. The result is a progressive bending or curling that gets worse over time if the underlying cause goes unaddressed. Several conditions can trigger that imbalance, from poorly fitting shoes and bunions to nerve damage from diabetes, rheumatoid arthritis, and plain genetic bad luck. The good news is that treatment options range from simple shoe changes and padding to surgical correction, depending on how far the deformity has progressed.
How Toes Twist in the First Place
Your lesser toes (the four smaller ones) are controlled by two sets of muscles. The intrinsic muscles sit inside the foot itself, while the extrinsic muscles originate higher up in the leg and send long tendons down into the toes. When these two groups pull evenly, the toe stays flat. When one group overpowers the other, or when the small stabilizing ligaments on the underside of the toe joint weaken, the toe buckles at one or more of its joints. That buckling is what produces the curled, cocked-up, or crossed-over appearance people notice.1Orthopaedics & Traumatology: Surgery & Research. Lesser-toe deformity
Research comparing people with hammer toes to those without found that the ratio of extensor (top-of-toe) to flexor (bottom-of-toe) muscle strength was roughly two to three times higher in the affected group.2PubMed Central. Muscle imbalance and reduced ankle joint motion in people with hammer toe deformity In plain terms, the muscles pulling the toe upward were far stronger relative to the ones pulling it down, so the toe got stuck in a bent position. That same study found reduced ankle motion in the hammer toe group, suggesting the problem often involves the whole foot and lower leg, not just the toe itself.
Doctors use different names depending on which joint buckles. A hammer toe bends at the middle joint, a claw toe curls at both the middle and end joints (so the toe looks like it’s gripping the ground), and a mallet toe flexes only at the joint nearest the tip. For everyday purposes the distinction matters mostly for choosing the right treatment, but the underlying story is the same: muscle and tendon imbalance, often combined with weakening of the joint capsule or the plantar plate ligament on the underside of the toe.
Shoes That Speed Up the Problem
Tight, narrow, or high-heeled shoes are one of the most common accelerators of toe deformity. A shoe with a pointed or shallow toe box squeezes the toes together and forces them into positions they were not designed to hold for hours at a time. A study measuring forefoot pressures in healthy women found that the shape and volume of the toe box significantly changed how much pressure landed on the toes, and that certain toe box designs created pressure patterns likely to contribute to deformity over time.3PubMed Central. The effect of shoe toe box shape and volume on forefoot interdigital and plantar pressures in healthy females
High heels compound the issue because they shift your body weight forward onto the ball of the foot, increasing the load on the small joints of the toes. Over years, that repeated stress stretches the plantar plate and joint capsules, giving the stronger extensor tendons free rein to pull the toe upward. This is one reason toe deformities are more common in women: decades of wearing shoes that prioritize style over toe space take a measurable toll.
Bunions and Crossover Toes
If you have a bunion (hallux valgus), it does not just affect the big toe. As the big toe angles inward, it can physically push the second toe out of alignment. This is how a “crossover toe” develops: the second toe rides up and over the big toe, sometimes dramatically. A study of patients with crossover second toes found an increased incidence of both bunions and degenerative arthritis at the big toe joint in the same feet.4PubMed. Crossover second toe: demographics, etiology, and radiographic assessment The crossover deformity is most commonly seen in women over 50 and frequently appears alongside a bunion.5PubMed.

The structural anatomy of the foot also plays a role. Radiographic analysis has shown that people whose second metatarsal bone protrudes further than average are more likely to develop plantar plate tears and medial deviation of the second toe. Having a wider angle between the first and second metatarsals, as well as visible splaying of the digits, were both associated with higher odds of plantar plate damage during surgery.6PubMed. The underlying osseous deformity in plantar plate tears: a radiographic analysis So in some cases the foot’s own bone geometry sets the stage for trouble long before shoes or aging contribute.
Nerve Damage, Diabetes, and Inflammatory Disease
Diabetes is one of the most important medical causes of toe deformity. Diabetic neuropathy gradually damages the nerves that control the small intrinsic muscles of the foot. As those muscles waste away, the balance of power shifts to the extrinsic muscles, and the toes curl into claw positions. A study using MRI to measure muscle volume found that people who had both neuropathy and claw toes had significantly smaller intrinsic foot muscles compared to every other group, whether those other participants had neuropathy alone, claw toes alone, or neither.7PubMed Central. Neuropathy, claw toes, intrinsic muscle volume, and plantar aponeurosis thickness in diabetic feet The combination of nerve damage and muscle wasting together drove the deformity, while either factor on its own did not cause the same degree of muscle loss.
Broader musculoskeletal problems in diabetes extend beyond the toes. Patients’ age, duration of diabetes, blood sugar control (measured by HbA1c), and the presence of microvascular complications are all associated with a higher burden of musculoskeletal disorders including joint contractures and foot deformity.8PubMed Central. The musculoskeletal disorders in diabetic patients and the evaluation of their relationship with metabolic parameters and microvascular complications If you have diabetes and notice your toes starting to curl, it is worth flagging with your doctor sooner rather than later, because the nerve damage driving the change can also reduce sensation and lead to skin breakdown and ulcers on the tops or tips of bent toes.
Rheumatoid arthritis is another major driver. Chronic inflammation erodes the joint capsules and surrounding soft tissues, producing hallux valgus and deformity of the lesser toe joints.9PubMed Central. Rheumatoid forefoot deformity: pathophysiology, evaluation and operative treatment options The pattern in rheumatoid feet tends to involve multiple toes simultaneously and can progress faster than deformities caused by shoes or aging alone. Other neuromuscular conditions, including Charcot-Marie-Tooth disease, stroke-related spasticity, and spinal cord injuries, can all produce toe deformities through similar mechanisms of muscle imbalance.
Genetics and Aging
You may look at your twisted toes and wonder whether you simply inherited them. The answer, at least partly, is yes. The Framingham Foot Study examined heritability of lesser toe deformities in a large community-based cohort and found that after adjusting for age, sex, and body mass index, roughly 56% of the variation in lesser toe deformity could be attributed to genetics. The heritability was even higher in women (about 85%) and in people over 70, where it reached 80% to 90%.10PubMed Central. Hallux Valgus and Lesser Toe Deformities are Highly Heritable in Adult Men and Women: the Framingham Foot Study That does not mean genes are destiny, but it does mean some people are structurally predisposed to develop these problems regardless of what shoes they wear.
Aging itself weakens the tissues that keep toes straight. Ligaments and tendons degenerate over time, and without active prevention measures, deformities including claw toes and hammer toes become increasingly likely.11PubMed. The Ageing Foot Fat pads on the ball of the foot thin out with age, which removes a natural cushion and shifts more mechanical stress onto the toe joints. The foot also tends to widen and flatten over the decades, changing how forces distribute across the forefoot and contributing to the progressive buckling of toes that many people first notice in their 50s or 60s.
Conservative Treatments
If your toes are still flexible (you or a doctor can straighten them by hand), conservative treatment is the usual first step. The goal is to relieve pain, reduce pressure on the bent joints, and slow further progression. Several approaches can help:
- Metatarsal pads: A pad placed just behind the ball of the foot redistributes pressure away from the metatarsal heads. One study found that a metatarsal pad positioned about 6.5 mm behind the second metatarsal head cut peak pressure by roughly a third, and a thicker insole reduced it by another 23% on top of that.
- Toe sleeves and cushions: Silicone or gel sleeves placed over the bent joint protect it from rubbing against the shoe and reduce corn formation.
- Toe separators and spacers: These are useful when toes overlap or when a bunion is pushing the second toe out of line.
- Wider, deeper shoes: Simply switching to footwear with a roomy toe box can relieve a surprising amount of discomfort and slow progression.
A review of the evidence on shoe modifications and orthoses confirmed that these measures can alleviate symptoms in most cases. Custom-made silicone orthoses reduced peak plantar pressures in rigid-stage deformities, though the benefit was less clear for flexible-stage deformities.12PubMed. The effectiveness of shoe modifications and foot orthoses in conservative treatment of lesser toe deformities: a review of literature More generally, applying insoles or orthoses combined with proper footwear is considered a first-line management approach for forefoot disorders.13Yeungnam University Journal of Medicine. Forefoot disorders and conservative treatment
Toe exercises and stretching are often recommended alongside these devices. Strengthening the intrinsic foot muscles (through exercises like towel scrunches, marble pickups, or simply spreading and curling the toes) may help rebalance the muscle forces acting on the toe. The evidence for exercise alone reversing an established deformity is thin, but as part of a broader conservative plan it makes biomechanical sense to try to rebuild the muscles that have weakened.
When Surgery Makes Sense
Surgery comes into the picture when the toe is rigid (you cannot straighten it manually), when conservative measures have failed to control pain, or when the deformity is causing secondary problems like chronic corns, ulcers, or difficulty walking. The main surgical options include tendon transfers, joint fusion (arthrodesis), and joint reshaping (arthroplasty).14Journal of the American Academy of Orthopaedic Surgeons. Hammertoes: Anatomy, Pathophysiology, and Comprehensive Treatment Strategies The specific procedure depends on which joints are affected, how rigid the deformity is, and what other problems exist in the foot.
In a typical hammer toe correction, the surgeon either removes a small piece of bone to straighten the joint (arthroplasty) or fuses the joint in a straight position using a pin or implant (arthrodesis). When the muscle imbalance is the main driver, a tendon transfer can reroute the pull of one tendon to restore more balanced forces. If a bunion is part of the picture, correcting it at the same time often gives the lesser toes enough room to settle back into alignment.
Minimally invasive techniques have become increasingly popular. A retrospective comparison of minimally invasive and open hammer toe correction found that bone healing time was similar between the two approaches, averaging about 8 to 9 weeks in both groups, and return to activity was comparable at roughly 10 weeks.15PubMed. Minimally Invasive Versus Open Hammertoe Correction: A Retrospective Comparative Study The recurrence rate was low in both groups. A separate study from Saudi Arabia found that minimally invasive patients had shorter hospital stays (about 2 days versus 3.5 days) and faster early recovery (a median of 2 weeks versus 4 weeks), with fewer wound complications. Malalignment and recurrence rates at one year were comparable between the two techniques.16Journal of Advanced Trends in Medical Research. Outcomes of Minimally Invasive Surgery versus Traditional Open Surgery in Managing Forefoot Deformities: A Retrospective Cohort Study in Saudi Arabia The takeaway is that minimally invasive surgery offers a somewhat easier early recovery without sacrificing long-term results, though both approaches work well.
Complications Worth Knowing About
No surgery is risk-free, and toe corrections have their own quirks. One of the most talked-about complications is “floating toe,” where the corrected toe sits slightly elevated and does not touch the ground when you stand. This is most commonly associated with a procedure called Weil osteotomy, used to shorten a metatarsal bone and decompress the toe joint. Studies report floating toe rates anywhere from 15% to 68% after a Weil osteotomy, a remarkably wide range that reflects differences in surgical technique and how the complication is defined.17PubMed Central. Advances in the Causes and Treatment of Floating Toes after the Weil Osteotomy: A Scoping Review A floating toe is not always painful, but it can be annoying and sometimes requires additional treatment.
Other potential complications include stiffness (the corrected toe may not bend as freely as before), recurrence of the deformity over years, transfer pain (where correcting one area shifts stress to a neighboring metatarsal), and infection. Pins that hold the toe straight during healing sometimes need early removal if they irritate surrounding tissue. These risks are generally manageable, but they are worth discussing with your surgeon before deciding to proceed, especially if your main complaint is cosmetic rather than functional.
Choosing Shoes That Actually Help
Whether you are trying to prevent toe deformities, manage existing ones conservatively, or protect a surgical repair, shoe choice matters more than most people realize. A systematic review of footwear research for older adults identified several design elements that protect foot health: a toe box wide and deep enough to accommodate the actual shape of the foot, limited heel height, a firm insole and midsole for support, an outsole with adequate tread, and a secure closure mechanism.18Maturitas. Shoe design for older adults: Evidence from a systematic review on the elements of optimal footwear
In practical terms, that means looking for shoes where you can wiggle all five toes freely when standing, where the heel is no more than an inch or so high, and where the shoe holds your foot in place without squeezing. Athletic shoes and many walking shoes meet these criteria easily. Fashion shoes with pointed toe boxes, stiletto heels, or flimsy flat soles generally do not. If you have an existing deformity, you can sometimes get a shoe stretched at a cobbler to create more room over the bent joint, or switch to brands that offer extra-depth or extra-wide options.
How Twisted Toes Affect Daily Life
Toe deformities are easy to dismiss as a cosmetic annoyance, but the evidence says otherwise. A case-control study comparing elderly adults with lesser toe deformities to those without found that the deformity group scored significantly lower on quality-of-life measures related to both foot health and general health.19PubMed Central. Foot health-related quality of life among elderly with and without lesser toe deformities: a case–control study Pain from corns, difficulty finding comfortable shoes, changes in walking patterns to avoid discomfort, and reduced activity levels all feed into each other. People with painful toe deformities often walk less, which weakens the very muscles that might slow the deformity’s progression, creating a cycle that is hard to break without intervention.
Balance is another concern, especially in older adults. When toes cannot grip the ground properly, the foot’s ability to make fine adjustments during standing and walking is compromised. This can increase fall risk, a problem that has real consequences for anyone over 65. Addressing toe deformities is not vanity. For many people, it is a meaningful part of staying mobile and independent as they age.
