A metatarsal pad for Morton’s neuroma should sit just behind the metatarsal heads, not directly under them. The goal is to prop up the metatarsal shafts so the painful nerve in the intermetatarsal space gets less compression during weight-bearing. Getting the placement even slightly wrong can make symptoms worse rather than better, which is why this seemingly simple question trips up so many people trying to manage their foot pain at home.
What Morton’s Neuroma Is and Why Pad Position Matters
Morton’s neuroma is not actually a tumor. It is a thickening of the tissue around a digital nerve in the forefoot, most often in the third intermetatarsal space (between the third and fourth metatarsal heads), and less commonly in the second.1PubMed Central. Morton’s neuroma – Current concepts review The thickening results from chronic mechanical irritation where the nerve passes beneath the transverse intermetatarsal ligament, leading to a buildup of fibrous tissue around the nerve along with swelling and degeneration of blood vessels in the area.2PubMed Central. Retrospective Study of Morton’s Neuroma: Clinical, Paraclinical, and Therapeutic Assessment of 10 Cases The result is burning pain, numbness, or a sensation of standing on a pebble in the ball of the foot.
Because the nerve is compressed between the metatarsal heads, the logic of pad placement is straightforward: you want to spread the metatarsal heads apart or lift the metatarsal shafts so the heads splay slightly when you step down. That means the pad needs to sit behind (proximal to) the metatarsal heads, supporting the arch of the metatarsals rather than pressing up directly into the area where the nerve is being irritated. A pad placed too far forward actually pushes up into the tender zone and can increase pressure on the already-inflamed nerve.
The Proximal Rule and What the Research Shows
The consistent recommendation from the literature is that a metatarsal pad belongs just proximal to the metatarsal heads. A systematic review of non-surgical treatments for Morton’s neuroma described the correct position as fitting “the plantar aspect of the foot, proximal to the metatarsal heads at the distal border,” with the pad tapering in thickness from front to back and from center toward the medial and lateral edges.3PubMed Central. The effectiveness of non-surgical interventions for common plantar digital compressive neuropathy (Morton’s neuroma): a systematic review and meta-analysis A broader review of conservative treatments echoed this, finding that most authors recommend an insole with a retrocapital pad just proximal to the metatarsal heads to displace pressure away from the pinched nerve.4PubMed Central.

The biomechanical reasoning behind this placement has been tested in pressure studies. In older adults with forefoot pain, metatarsal domes placed proximal to the metatarsal heads significantly reduced peak pressure at the forefoot by roughly 45 to 60 kPa compared to wearing shoes without any pad. The pressure reduction was greatest in the area just distal to the metatarsal heads, which is precisely where Morton’s neuroma causes the most discomfort. And for some pad configurations, the pressure was not simply shifted to the area under the pad itself; it was genuinely redistributed more evenly.5PubMed Central. Effects of metatarsal domes on plantar pressures in older people with a history of forefoot pain
A separate study found that a metatarsal dome positioned about 5 mm proximal to the metatarsal heads reduced peak forefoot pressure by about 17 percent compared to shoes alone, one of the strongest reductions among the different forefoot pad types tested.6PubMed Central. Comparison of the pressure-relieving properties of various types of forefoot pads in older people with forefoot pain The consistent finding across these studies is that effective placement is close to, but not under, the metatarsal heads.
What Happens When the Pad Is Placed Too Far Forward
Getting placement wrong in the forward direction is a common mistake, and the consequences are not trivial. A finite element modeling study of the foot found that a distally placed metatarsal pad can actually reverse the intended pressure-relief effect under the metatarsal heads. The researchers attributed this to the way a forward-placed pad interacts with the plantar tissue near the metatarsal heads, particularly the plantar fascia. Instead of lifting the shafts and spreading the heads, the pad ends up pressing into the already-loaded area. The study emphasized that a uniform pattern of tissue compression under the metatarsal shafts is needed for effective pressure relief.7PubMed Central.

This finding matters for people with Morton’s neuroma because the nerve is already irritated by compression between the metatarsal heads. Pushing a pad up directly into that area is not just unhelpful; it can make the burning and numbness worse. If you place a pad and notice that your symptoms increase rather than decrease, the pad is almost certainly too far forward.
How to Find the Right Spot on Your Own Foot
If you are using a self-adhesive metatarsal pad from a pharmacy or online retailer, the practical challenge is locating your metatarsal heads by feel. Here is a reliable way to do it: sit down and run your thumb along the sole of your foot from the toes toward the arch. You will feel the bony prominences of the metatarsal heads as firm round bumps in the ball of your foot, roughly in a line across the forefoot. The pad’s front edge should sit just behind that line of bumps, not on top of them.
A useful trick is to mark the position before sticking the pad down. Press a fingertip firmly into the ball of your foot while your toes are flexed back. The metatarsal heads become more prominent and easier to locate. Mark the skin with a washable pen, then use that mark as your reference when placing the pad on your insole or directly on the skin. The highest point of the pad should align roughly with the metatarsal shafts, about 5 to 10 mm behind the heads.
Placement also depends on which intermetatarsal space is affected. For the more common third-space neuroma, the pad should be centered between the second and fourth metatarsal heads. For a second-space neuroma, shift it slightly medially. The pad does not need to be wide enough to cover the entire forefoot; it just needs to support the metatarsals on either side of the affected nerve so those heads separate slightly under load.
Does Exact Positioning Matter as Much as People Think?
The evidence on this point is surprisingly mixed. While the general proximal-to-the-heads rule is well supported, one study comparing metatarsal pads placed right at the proximal border of the metatarsal heads versus pads placed 10 mm further forward from that border found no clear difference in pressure-reducing effectiveness between the two positions.8PubMed Central. Comparison of the Forefoot Pressure-Relieving Effects of Foot Orthoses That suggests there is a workable zone rather than a single perfect millimeter mark, and small shifts within the proximal region may not dramatically change outcomes.
The real danger zone is not modest variation within the proximal area but placing the pad clearly under or in front of the metatarsal heads. The modeling data described earlier showed that this distal misplacement can reverse the pressure-relief effect entirely. So think of it as a safe zone with a hard forward boundary: anywhere from just behind the heads to a centimeter or so further back is likely fine, but crossing forward of the heads is where things go wrong.
Pad Intolerance and the Break-In Period
Even with correct placement, metatarsal pads feel strange at first. You are adding a raised surface inside your shoe that your foot has not experienced before, and some discomfort during the first week is normal. In a study of 60 patients fitted with custom foot orthotics that included metatarsal pads, about one in six reported pain or discomfort they attributed to the pad after the first week of use. However, when those patients were reassessed, most of the complaints turned out to be related to inadequate shoe size or simply needing encouragement to persist through the adjustment period. Only one patient out of the original 60 ultimately needed the pad itself adjusted.9PubMed Central. Report of metatarsal pad intolerance in a cohort of 60 patients treated with customized foot orthotics
The practical takeaway here is that your shoes need enough room to accommodate the added bulk. A pad inside a shoe that is already tight will create new pressure points and pain that has nothing to do with your neuroma. If you are adding a metatarsal pad for the first time, try it in your most spacious footwear and give yourself at least a week before deciding it is not working. That said, sharp increased pain at the neuroma site itself, as opposed to general foot soreness, is a signal that placement is off, not that you need more time to adjust.
Pad Shape, Thickness, and Material
Metatarsal pads come in two basic shapes: teardrop pads, which are flat-backed and taper to a point, and metatarsal domes, which are rounded and fuller. Both work by the same principle, but domes tend to provide more lift. The proximal pressure-relief studies cited above used dome-style pads, and the results suggest domes can achieve meaningful pressure redistribution without simply transferring all the load to a new spot under the metatarsal shafts.5PubMed Central. Effects of metatarsal domes on plantar pressures in older people with a history of forefoot pain
Material matters too. Softer materials with some memory, such as layered foam combinations, have been shown to reduce peak pressure at the metatarsal heads by roughly a quarter to a third compared to barefoot conditions.10PubMed Central. Preliminary investigation on the reduction of plantar loading pressure with different insole materials Firmer pads hold their shape longer and provide more structural lift, but they can feel aggressive underfoot, especially in the first few days. If you have tried a firm pad and found it unbearable despite correct placement, switching to a softer material with the same shape and position is worth trying before abandoning pads altogether.
Self-adhesive pads applied directly to an insole tend to migrate over time as the adhesive weakens, which can silently move the pad out of position. Checking pad position every few days and replacing the adhesive when it loses grip is important. Custom orthotics that incorporate a built-in metatarsal support avoid this issue entirely, since the pad is integrated into the structure of the insole.
Running and High-Impact Activity
If you run or exercise with Morton’s neuroma, the evidence for standalone metatarsal pads during high-impact activity is less encouraging. One study comparing metatarsal pad orthotics to forefoot cushioning orthotics during running found that the metatarsal pad configuration did not significantly reduce forefoot peak pressure compared to a control insole. Forefoot cushioning, by contrast, did produce a meaningful reduction.11PubMed Central. The effect of foot orthoses with forefoot cushioning or metatarsal pad on forefoot peak plantar pressure in running The forces involved in running are substantially higher than in walking, and a small pad may not provide enough mechanical advantage to separate the metatarsal heads against that load.
This does not mean you should ditch the pad for running, but it does suggest that a pad alone may not be sufficient. Combining a metatarsal dome with a cushioned insole, choosing shoes with a wider toe box, and reducing mileage during flare-ups are all strategies that address the higher forces at play. Some runners find that switching to a shoe with more forefoot rocker geometry naturally reduces peak pressure under the metatarsal heads during toe-off.
When Pads Are Not Enough
Metatarsal pads are typically the first line of conservative treatment, but they have real limitations. A systematic review and meta-analysis that pooled results from studies of footwear modifications and padding for Morton’s neuroma found that roughly a third of patients treated with padding and footwear changes reported success at an average of about four and a half months.3PubMed Central. The effectiveness of non-surgical interventions for common plantar digital compressive neuropathy (Morton’s neuroma): a systematic review and meta-analysis That means about two-thirds did not get adequate relief from conservative shoe-based measures alone. The same review found that corticosteroid injections had substantially better odds of success at six months compared to padding.
This is worth keeping in perspective. A pad is cheap, low-risk, and easy to try. Even if you are among the majority who eventually need additional treatment, a properly placed metatarsal pad can make the condition more bearable while you explore other options. And for the roughly one in three people for whom pads do work, they offer a long-term solution without injections or surgery. The key is not to interpret early discomfort as failure, but also not to persist with pads indefinitely if your symptoms are unchanged after a few months of correct use.
Subjective Pain Improvement and Pressure Changes
One finding that may be reassuring if you are using a metatarsal pad and noticing modest but real improvement: a prospective study of metatarsalgia patients found that metatarsal pad use reduced both peak pressure and the cumulative pressure over time under the second metatarsal head, and these reductions correlated with improved subjective pain scores.12PubMed Central. Correlations between subjective treatment responses and plantar pressure parameters of metatarsal pad treatment in metatarsalgia patients: a prospective study In other words, the measured pressure changes from a properly placed pad are big enough to actually translate into noticeable pain relief for many people, not just a laboratory finding on a pressure plate.
The study also hints at something clinicians often observe: the people who benefit most from metatarsal pads tend to have symptoms centered under a specific metatarsal head rather than diffuse forefoot pain. If your Morton’s neuroma produces a well-localized burning sensation between two specific toes, a correctly placed pad has a good chance of helping. If your pain is vague and spread across the entire ball of the foot, the problem may be more complex than a single nerve compression, and pads alone are less likely to resolve it.
Gait Changes With a Metatarsal Pad
Adding a raised surface inside your shoe changes how your foot interacts with the ground, and you might notice subtle differences in your walking pattern. A study measuring spatiotemporal gait parameters found that metatarsal pad users walked slightly faster and spent less time in the stance phase of each step, though these changes were modest and did not reach statistical significance for most measures.13Journal of Prosthetics Orthotics and Science Technology. EFFECT OF METATARSAL PAD USE ON SPATIOTEMPORAL GAIT PARAMETERS ON FOREFOOT PAIN The implication is that a pad may help you move with slightly less guarding or limping when forefoot pain is reduced, even if the gait changes themselves are not dramatic.
If you notice that you are walking more normally with a pad in place, that is a good sign. People with Morton’s neuroma often unconsciously alter their gait to avoid loading the painful area, which can cascade into hip, knee, or lower-back strain over time. A pad that lets you walk without compensating is doing more than just relieving forefoot pain.
