Why Is My Toe Going Sideways? Causes and Treatments

A toe that gradually angles toward its neighbor is almost always a sign that the soft-tissue structures holding a toe joint in place have started to shift, stretch, or fail. The most common version is hallux valgus, the medical name for a bunion at the base of the big toe, but the big toe is not the only one that can drift. The second toe, the fifth toe, and even the middle toes can deviate sideways under the right circumstances, and the causes and treatments differ depending on which toe is involved.

What Is Happening Inside the Joint

Your toes stay pointing forward because a network of ligaments, tendons, and small bones keeps each joint aligned. In the case of your big toe, the first metatarsophalangeal joint sits atop a structure called the sesamoid complex, which includes seven muscles, eight ligaments, and two sesamoid bones (small, seed-shaped bones embedded in tendons beneath the joint). When the first metatarsal bone drifts inward away from this complex, the sesamoids stay in place, some of the surrounding ligaments rupture or weaken, and others tighten on the opposite side. That imbalance is what pulls the big toe outward toward the second toe and creates the bony bump you can see and feel on the inner edge of your foot.¹

A similar ligament-and-tendon tug-of-war explains sideways drift in the smaller toes, though the specific structures involved differ. In every case the pattern is the same: one side of the joint loosens while the other side contracts, and the toe gets pulled in the direction of the tighter tissue. Once that process starts, every step you take reinforces it, because ground-reaction forces push the toe further into its new position.

Which Toe Is Drifting Matters

Not every sideways toe is a bunion. Identifying which toe is moving and in which direction helps narrow down the problem and the right treatment.

Big Toe Angling Outward (Hallux Valgus)

This is the classic bunion. The big toe leans toward the second toe, sometimes overlapping it in advanced cases, and a bony prominence develops on the inner side of the foot. Hallux valgus is one of the most frequently treated forefoot deformities, and its causes range from inherited foot shape and loose ligaments to footwear habits and conditions like rheumatoid arthritis.²

Second Toe Crossing Over the Big Toe

Crossover second toe deformity happens when the ligaments on the outer side of the second toe’s base joint deteriorate. The toe initially drifts inward, toward the big toe, and over time it can ride up and actually cross over the big toe.³ Cadaver studies have shown that the damage goes deeper than just the outer ligaments. The plantar plate, a thick pad of tissue on the bottom of the joint, also shifts and deforms, and the flexor tendons displace along with it. Both major stabilizing structures of the joint end up compromised.⁴ This condition often develops alongside a bunion, because as the big toe pushes into the second toe’s space, it destabilizes the second toe joint.

Little Toe Angling Inward (Tailor’s Bunion)

A bunionette, or tailor’s bunion, is essentially the mirror image of hallux valgus but at the fifth metatarsal. The little toe angles inward toward the fourth toe, and a painful bump forms on the outside of the foot. The name comes from the days when tailors sat cross-legged on hard floors, putting chronic pressure on the outer edge of the foot. Today it is more often linked to shoe pressure, inherited foot structure, or a naturally wide splay of the fifth metatarsal.²

The Footwear Question

Shoes get blamed for almost every foot problem, and there is real evidence connecting certain shoe features to sideways toe drift. A study of women who regularly wore high heels found significant correlations between heel use and hallux valgus as well as fifth-toe deformity.⁵ Research on toe-box shape has shown that narrower, more pointed designs increase pressure between the toes and under the forefoot, creating conditions that could push toes out of alignment over time.⁶

The picture is not as clean-cut as “heels cause bunions,” though. A controlled cohort study comparing nearly 200 women found no statistically significant differences in forefoot deformities or joint disease on radiographs between habitual high-heel wearers and women who avoided them.⁷ That result suggests that footwear alone is probably not sufficient to cause a sideways toe in someone whose foot anatomy and ligaments are not already predisposed. Shoes can accelerate a process that genetics or joint laxity started, but blaming them as the sole cause overstates the evidence.

Neurological and Other Underlying Causes

Sometimes a toe drifts sideways not because of shoes or bunion mechanics but because of an underlying condition affecting the nerves or muscles that control foot movement. Claw toes, in which the smaller toes curl downward and can also deviate sideways, are produced by factors ranging from inflammatory arthritis and hallux valgus to congenital deformity and ill-fitting footwear. Among all the known contributors, neurological diseases are considered the most common cause of claw toe deformity.⁸

Conditions like Charcot-Marie-Tooth disease, peripheral neuropathy from diabetes, stroke, and spinal cord injuries can weaken the small intrinsic muscles of the foot while leaving the longer extrinsic muscles intact. That imbalance pulls the toes into abnormal positions. If your toes are drifting and you also notice numbness, weakness in the feet, a high arch that seems to be getting higher, or difficulty lifting the front of your foot, a neurological evaluation is worth pursuing before focusing purely on the toe itself.

Nonsurgical Treatments

For mild to moderate cases, conservative approaches can slow or stop the progression of a sideways toe and reduce pain, even if they do not fully reverse the deformity.

Toe separators have accumulated a surprisingly solid evidence base. A systematic review found that combining exercise with toe separators, night splints, and dry needling was the most effective nonsurgical strategy for reducing the hallux valgus angle.⁹ A meta-analysis within the same review concluded that orthoses with a built-in toe separator could reduce the hallux valgus angle by roughly two to six degrees and improve patients’ subjective comfort by relieving stress on the ligaments and bones around the big toe.⁹

In one trial, patients with moderate bunions who wore custom silicone toe separators for six hours per night over twelve months saw a significant reduction in their hallux valgus angle (about three degrees on average), while the control group’s angle actually increased. Pain also dropped in the separator group, with no serious complications.⁹ Another study found that insoles with a built-in separator reduced bunion pain effectively, and while neither the insole nor a night splint corrected the underlying deformity, both prevented the bunion from getting worse.⁹

A three-month program that combined foot mobilization exercises with toe separators produced broader improvements in patients with moderate hallux valgus, including better ankle range of motion, stronger toe grip, and measurable changes on X-rays, compared to a control group.⁹ The takeaway from the research is that toe separators work best when combined with targeted exercise rather than used passively, and that consistency over months matters more than the specific brand or material.

Beyond separators, wider shoes with a roomier toe box, padding over pressure points, and taping techniques can all reduce daily pain. For crossover toe and plantar plate problems, stiff-soled shoes or rocker-bottom designs limit how much the joint bends during walking and can take pressure off the damaged ligaments.

When Surgery Makes Sense

Surgery becomes a realistic option when pain persists despite months of conservative treatment, when the deformity is severe enough to interfere with walking or shoe fitting, or when the toe has become rigid in its displaced position. For hallux valgus, more than a hundred surgical procedures have been described over the years, which tells you that no single technique is perfect for every patient.

The Lapidus procedure, which fuses the joint at the base of the first metatarsal, is considered a durable solution for moderate to severe bunions, especially when there is excessive looseness in the first ray of the foot.¹⁰ Another common approach is the chevron osteotomy, which cuts and realigns the metatarsal head and is typically used for milder deformities. A comparison of revision rates across these procedures found no statistically significant difference in the likelihood of needing a second surgery, though the Lapidus group had higher rates of nonunion (the bone failing to heal across the fusion site) and hardware-related pain.¹¹

Minimally invasive techniques have gained popularity in recent years. A comparison of the modified Lapidus procedure with a minimally invasive distal transverse osteotomy found that both were effective at improving pain and mobility, and patients maintained good function after either approach.¹² The minimally invasive version appeals to patients because of smaller incisions and potentially faster recovery, though long-term data are still accumulating.

For crossover second toe, surgical repair usually involves reconstructing or repairing the plantar plate and rebalancing the ligaments around the joint. If the second toe deformity exists alongside a bunion, both problems are often addressed in the same operation, because fixing the bunion alone still leaves the second toe unstable.

How Often Bunions Come Back After Surgery

Recurrence is one of the most underappreciated realities of bunion surgery. A meta-analysis pooling data across multiple studies found that roughly a quarter of hallux valgus corrections recur.¹³ That does not mean a quarter of patients need a second operation, since mild recurrence may not cause symptoms, but it is a much higher number than most patients expect going in. The strongest predictor of recurrence was the postoperative angle of the big toe. In other words, how well the surgeon corrected the alignment at the time of surgery mattered more than almost any other factor.¹³

A large-scale analysis of over 150,000 bunion operations in England offered a more optimistic long-term picture: revision-free survival was about 93% at 25 years, meaning only around 7% needed a formal revision over a quarter century. About 5% had a revision correction and roughly 3% ended up needing a fusion procedure. Women, patients between ages 40 and 59, and those in more socioeconomically deprived groups had somewhat higher revision risk.¹⁴ The gap between “recurrence visible on an X-ray” and “recurrence bad enough to need another surgery” is significant. Many patients with mild recurrence live comfortably with orthotics or accommodative shoes after their initial procedure.

What Happens If You Ignore a Drifting Toe

A sideways toe that is not painful today may not stay that way. As the foot ages, skin dries out and calluses develop over areas of abnormal pressure. Ligaments and tendons continue to degenerate, and without intervention, deformities like claw toes, hammer toes, and bunions tend to progress. Bony spurs can form, and the altered mechanics of walking can lead to stress fractures, bursitis, and joint inflammation that significantly reduce quality of life.¹⁵

A drifting big toe also puts the adjacent toes at risk. As hallux valgus progresses, the big toe crowds into the second toe, which can trigger the crossover deformity described earlier or cause painful corns between the toes. The cascade effect means that one untreated deformity can eventually lead to problems across the entire forefoot. This does not mean every bunion needs aggressive early treatment, but it does mean that “wait and see” should involve periodic check-ins rather than pure neglect.

What Barefoot Populations Tell Us About Foot Shape

Some of the most interesting evidence about why toes drift comes from comparing populations that habitually wear modern shoes with those that go barefoot or wear minimal footwear. A study comparing foot strength and arch characteristics between minimally shod and conventionally shod adults found that the minimally shod group had arches that were about 9% higher and roughly 27% stiffer. About a third of conventionally shod participants had low arches, while only one person in the minimally shod group did.¹⁶

Research using machine learning to classify feet as habitually shod or unshod found that the forefoot region was the most reliable giveaway. The shape of the forefoot, especially under dynamic conditions like running, differed enough between the two groups that an algorithm could tell them apart with high accuracy.¹⁷ In habitually barefoot populations, the toes tend to splay wider and the forefoot is broader, which naturally gives each toe more room and distributes load differently across the joints.

None of this means you should throw out your shoes and expect your bunion to reverse. Once the joint has remodeled, going barefoot will not undo structural changes in bone and ligament. But the data do suggest that the modern foot environment, one where toes spend decades squeezed into a tapered box, contributes to the conditions that allow sideways drift. For people in the early stages of a toe misalignment, spending more time barefoot or in wide-toe-box footwear may help strengthen the intrinsic foot muscles that serve as a first line of defense against progressive deformity.
