Splayed toes, where the forefoot fans out and the metatarsal bones spread wider than normal, can be corrected through a range of approaches from simple inserts to bone-realigning surgery. How well any fix works depends on how far the splaying has progressed and what’s driving it. Mild cases often respond to toe separators, metatarsal pads, and targeted exercises, while advanced splayfoot with bunion or bunionette deformities typically needs surgical correction to bring the metatarsals back into alignment.
What Splayfoot Actually Is
The term “splayed toes” gets used loosely, but medically it refers to splayfoot (also called metatarsus latus), a condition where the long bones of the forefoot drift apart and the foot widens beyond its normal proportions. On an X-ray, doctors measure the angles between specific metatarsal bones to diagnose it. A splayfoot shows an angle between the first and second metatarsals greater than 12 degrees and between the fourth and fifth metatarsals greater than 8 degrees.1PubMed. Surgical correction of the splayfoot: the Giannestras procedure Another way to measure it is the total angle between the first and fifth metatarsals, where anything over 35 degrees on a weight-bearing X-ray indicates splayfoot.2European Society of Radiology. Between lines and silhouettes: radiographic evaluation of the angles of the foot
The splaying itself is rarely just a cosmetic nuisance. As the first metatarsal drifts inward and the fifth drifts outward, the big toe tends to angle toward the smaller toes, creating a bunion on the inner side of the foot. Meanwhile, the little toe angles inward, forming a bunionette on the outer side. This dual deformity is the hallmark of true splayfoot, and it changes how your weight distributes across the ball of the foot. Many people first notice it not because the foot looks wider but because walking starts to hurt, shoes feel tighter across the forefoot, or calluses build up under the second and third metatarsal heads.
Non-Surgical Approaches
For mild to moderate splaying, or for people who aren’t ready for or don’t need surgery, several conservative treatments can reduce symptoms and slow progression. None of them will fully reverse bony deformity once the metatarsals have shifted substantially, but they can make a meaningful difference in comfort and function.
Toe Separators and Spacers
Custom-molded silicone toe separators placed between the big toe and second toe can gradually nudge the hallux valgus angle back toward normal. A randomized trial testing these separators found that after 12 months, the group using them saw their hallux valgus angle decrease by about 3 degrees on average, while the control group’s angle actually worsened by about 2 degrees. Pain also dropped in the separator group.3PubMed. Effectiveness of the custom-mold room temperature vulcanizing silicone toe separator on hallux valgus: A prospective, randomized single-blinded controlled trial A few degrees may not sound dramatic, but in the context of early bunion formation, that difference separates a foot that’s getting worse from one that’s getting better. The catch is consistency: you have to wear them regularly, and they work best for mild deformities rather than advanced cases.
Metatarsal Pads and Insoles
A metatarsal pad is a small dome-shaped cushion placed just behind the ball of the foot inside your shoe. Its job is to lift and spread the metatarsal heads, redistributing pressure away from the painful spots underneath them. Research confirms that when placed correctly, metatarsal pads effectively reduce pressure under the metatarsal heads.4PubMed. Multistep measurement of plantar pressure alterations using metatarsal pads Flat supportive insoles and metatarsal pads have both been shown to relieve forefoot pressure and improve comfort.5PubMed Central. Comparison of the Forefoot Pressure-Relieving Effects of Foot Orthoses
Placement matters a lot. A pad that’s even a few millimeters off can fail to offload the right area or create new pressure points. Some people do well with off-the-shelf pads, but if you’re dealing with significant pain or a specific pressure pattern, a podiatrist can position them precisely. For runners, the evidence gets more nuanced: one study found that a forefoot cushioning insole outperformed a metatarsal pad insole for reducing peak pressure during running, suggesting that the best orthotic choice depends on your activity level and foot type.6PubMed Central.

Exercises
Strengthening the small muscles on the sole of the foot can help support the arch and maintain better forefoot alignment. Short foot exercises, where you contract the muscles along the sole to shorten and raise the arch without curling the toes, have been shown to improve arch height and reduce pain in people with fallen arches.7PubMed Central. Short foot exercises for flatfoot therapy: Status and prospects While this research focused on flatfoot, the exercises are relevant to splayfoot because a collapsing arch and a widening forefoot frequently go hand in hand. Stronger intrinsic foot muscles provide dynamic support that passive structures alone cannot.
Towel scrunches, marble pickups, and resistance band exercises that pull the big toe inward are commonly recommended as well. The evidence for these is more clinical-experience-based than trial-proven, but they carry essentially zero risk and complement other conservative measures.
Footwear Changes
Switching to shoes with a wider toe box is one of the most commonly recommended first steps for anyone with splayed toes. The logic is straightforward: cramming a wide forefoot into a narrow shoe makes everything worse. Interestingly, though, a study comparing people who habitually wore narrow toe box shoes to those who wore wide toe box shoes found no significant differences in ankle stability, functional ability, balance, range of motion, muscle strength, or perceived comfort between the two groups.8International Journal of Innovative Science and Research Technology. Exploring the Correlation Between Footwear Design (Narrow Toe Box Vs Wide Toe Box) on Ankle Foot Complex’s Stability, Ability and Posture in Healthy Adult That doesn’t mean shoe choice is irrelevant, but it suggests that simply buying wider shoes won’t fix the underlying structural problem on its own. Footwear changes are best thought of as a way to stop making things worse rather than as a standalone treatment.
When Surgery Becomes the Better Option
Conservative measures have limits. If the intermetatarsal angles are well beyond normal thresholds, if bunions and bunionettes are causing daily pain that pads and separators cannot manage, or if the deformity keeps progressing despite faithful use of orthotics, surgery is the realistic path to correction. The goal of splayfoot surgery is to narrow the forefoot by cutting and repositioning the metatarsal bones so they sit closer together.
Metatarsal Osteotomies
The most common surgical approach involves osteotomies, controlled cuts through the metatarsal bones that allow the surgeon to shift the bone segments into better alignment and then fix them in place with screws or plates. For splayfoot, this often means operating on both sides of the forefoot. A study evaluating simultaneous osteotomies on the first and fifth metatarsals found that all key measurements improved after surgery: the hallux valgus angle, the intermetatarsal angles, the width between the first and fifth metatarsal heads, and the maximum forefoot width all decreased significantly.9MOJ Orthopedics & Rheumatology. Radiological outcome of patients with splay foot following 1st and 5th metatarsal osteotomies performed simultaneously on the same foot Performing both corrections in a single operation avoids putting the patient through two separate recoveries.
Proximal osteotomies, where the cut is made near the base of the metatarsal rather than at the shaft or head, are preferred when the splaying is severe with a first intermetatarsal angle over about 14 degrees.10Operative Orthopädie und Traumatologie. Die proximale Open-Wedge-Osteotomie mit winkelstabiler Plattenosteosynthese zur Korrektur der Spreizfußdeformität mit Hallux valgus The closer to the base you make the cut, the more angular correction you can achieve. Shaft-level osteotomies work for moderate cases and are among the most widely performed bunion surgeries worldwide.
Tendon Transfer Procedures
Some surgeons take a soft-tissue approach, transferring tendons to pull the splayed metatarsals back together and reconstruct the forefoot’s transverse arch. One such procedure was shown to reduce the hallux valgus angle, narrow the gap between the first and second metatarsals, reposition the sesamoid bones under the big toe, and rebuild the transverse arch of the forefoot.11PubMed. Procedure of reconstructing transverse arch of the forefoot by transferring tendons for correcting hallux valgus Tendon transfers can be done alone or combined with osteotomies, depending on the severity and flexibility of the deformity.
The Giannestras Procedure
An older but established approach specifically designed for splayfoot correction addresses the dual deformity on both sides of the foot in a single comprehensive procedure. The technique targets the valgus of the great toe with its bunion alongside the varus of the fifth toe with its bunionette.1PubMed. Surgical correction of the splayfoot: the Giannestras procedure While newer osteotomy techniques have largely supplanted it for routine cases, the concept of addressing both borders of the foot simultaneously remains central to splayfoot surgery.
Recurrence After Surgery
One of the most important questions anyone considering splayfoot surgery should ask is how likely the problem is to come back. The answer depends heavily on how you define “recurrence.” A systematic review and meta-analysis of hallux valgus surgery using shaft osteotomies found that about 40 percent of patients still had a hallux valgus angle greater than 15 degrees at long-term follow-up. By a stricter threshold, about 20 percent had an angle over 20 degrees. Only around 2 percent had an angle over 25 degrees, which represents a more clinically significant recurrence. The revision rate, meaning the percentage who needed a second surgery, was between 0 and 3 percent.12PubMed Central. Recurrence rates with long-term follow-up after hallux valgus surgical treatment using shaft metatarsal osteotomies: a systematic review and meta-analysis
Those numbers deserve context. A 15-degree hallux valgus angle is close to the upper limit of normal and many people at that level have no symptoms at all. The fact that 40 percent drift above 15 degrees sounds alarming until you realize most of those patients are pain-free and functionally fine. The meaningful recurrence rate, where the deformity returns enough to warrant reoperation, is quite low. Still, it reinforces the importance of continuing conservative measures like appropriate footwear and orthotics even after successful surgery.
How Correction Changes Foot Function
Surgery fixes the angles, but what happens to the way the foot actually works? A study comparing plantar pressure in feet that had undergone hallux valgus correction to feet that still had the deformity found that the great toe regained significantly more pressure-bearing capacity after surgery, meaning it was doing its job of pushing off the ground again. However, the central forefoot showed higher peak pressures and forces after surgery compared to healthy feet that never had a bunion.13PubMed. Comparison of Plantar Pressure Distribution Between Postoperative Hallux Valgus Feet and Healthy Feet In practical terms, the big toe works better, but the middle of the forefoot may carry more load than it would in a foot that never had the problem. This is why many surgeons recommend custom orthotics or metatarsal pads even after a technically perfect surgical result.
Concerns about balance after toe correction are common but may be overblown. Research on how toe position affects standing balance found no significant difference in stability when the toes were in extension versus a neutral position.14PubMed Central. The Effect on Human Balance of Standing with Toe-Extension The foot’s balance mechanisms are more distributed than most people assume, and changing the alignment of one or two toes does not destabilize the system the way you might fear.
Related Conditions That Overlap With Splayfoot
Splayfoot rarely exists in isolation. Flat feet and splayfoot frequently appear together because both involve a loss of the foot’s normal arch architecture. People with flat feet have been found to have altered stiffness in the Achilles tendon, with higher stiffness at rest but lower stiffness during standing compared to people with normal arches.15PubMed. Passive mechanical properties of extrinsic foot muscles and Achilles tendon in adults with and without pes planus This suggests the tendon adapts to the altered foot posture, which can in turn affect how the forefoot handles load and may contribute to metatarsal spreading over time.
Morton’s neuroma surgery sometimes raises concerns about splayfoot because the procedure can involve cutting a ligament that holds the metatarsal heads together. However, research has confirmed that cutting this ligament does not increase the intermetatarsal angle or raise the risk of developing splayfoot.16PubMed. Transection of the deep metatarsal transverse ligament in Morton’s neuroma surgery does not increase risk of splayfoot development If you’ve been told you need neuroma surgery and are worried it will make your forefoot wider, the evidence suggests that specific concern is unfounded.
What Barefoot Populations Reveal About Prevention
One of the more interesting angles on splayfoot comes from comparing populations that habitually wear shoes to those that don’t. A study comparing shod Chinese runners to habitually unshod Indian runners found significant differences in foot width, hallux angle, and the spacing between the big and second toes.17PubMed Central. Foot Morphological Difference between Habitually Shod and Unshod Runners Unshod populations tend to have wider, more naturally splayed forefeet, but their hallux valgus angles are smaller. Their toes spread at the tips while the metatarsals remain properly aligned underneath. In other words, their toes splay but their metatarsals don’t, which is the opposite of what happens in splayfoot.
This distinction matters because it highlights that toe spreading is not inherently pathological. The problem in splayfoot is not that the toes are apart but that the metatarsal bones have drifted apart and the toes have deformed as a consequence. A foot that grew up unconstrained by shoes develops natural toe splay with a well-maintained transverse arch. A foot squeezed into pointed or narrow footwear for decades can develop metatarsal splaying with a collapsed transverse arch. The lesson is less about going barefoot forever and more about recognizing that the forefoot needs room to function, especially during the years when the foot is still developing. For adults who already have splayfoot, this insight is a reminder that prevention through footwear choices matters, even if reversing structural changes requires more active intervention.
