There is a number that Justin McCarthy cannot put down. Close to eight million people alive today are living with a permanent disability caused by untreated clubfoot, a condition in which a baby’s foot or feet turn inward and downward at birth. The fix costs roughly US$500 per child. The math, therefore, is not the problem. The reach is.
“The problem is effectively solved on the medical side,” says McCarthy, Senior Adviser for Philanthropy and Partnerships at MiracleFeet, a non-profit that has supported treatment for more than 120,000 children across 39 countries. “The only thing missing is reach. So the question stops being whether it can be done and becomes why it hasn’t been done faster.”

It is a question McCarthy has now decided to make his professional obsession, having taken on a broader mandate for MiracleFeet across Asia Pacific, a region that holds a disproportionately large share of the world’s untreated cases and where, as he frames it, “rising incomes and infrastructure make closing the gap realistic within a career rather than a century.”
A return that would make a VC blush
The economics of clubfoot treatment are, by any serious measure, extraordinary. A US$500 course of care generates an estimated US$130,000 in additional lifetime earnings for the child treated, a 260-to-one return. Left untreated, the condition locks children out of school, work, and full participation in their communities. Treated early, that same child walks, studies, and contributes to the economy.
So why hasn’t that argument unlocked more capital or government attention, particularly in a region that increasingly speaks the language of impact investing?
McCarthy is pragmatic about it. “Health budgets in low- and middle-income countries are already stretched across urgent, visible emergencies,” he says. Clubfoot affects approximately one in 800 births, which is significant in absolute terms, but not the kind of headline number that wins a triage fight against malaria or malnutrition. Crucially, it is not fatal. It is not loud. It loses.
What MiracleFeet is betting on is a shift: that philanthropic leaders and health ministries, once they understand the lifetime economics, become the most effective advocates for integrating clubfoot care into national systems.
Sri Lanka is already a proof point. In partnership with the College of Community Physicians of Sri Lanka, MiracleFeet successfully pushed for clubfoot services to be folded into the country’s public health infrastructure. The Ministry of Health now supports early detection, community surveillance, and re-engagement of children who have dropped out of treatment. It is the model MiracleFeet wants to replicate.
Where the system actually breaks
Trace the path a newborn in rural Southeast Asia has to travel for treatment to work, and the failure points stack up quickly.

First, someone has to identify the clubfoot and know it is correctable. Across much of the region, births happen far from specialists. Families are frequently told the condition is fate, or handed a referral they have no practical means of acting on.
Second, the treatment itself. The Ponseti method of treatment, a non-surgical approach using casting and bracing, demands months of weekly clinic visits followed by years of wearing a corrective brace. A parent who loses a day’s wages and travels for hours per appointment will, eventually, stop coming. A child who drops off mid-treatment will very likely relapse.
Third, trained providers thin out sharply outside major cities. The Philippines and Indonesia have enormous populations and significant unmet need. Cambodia and Laos represent earlier-stage opportunities. None of these markets have the provider density or referral infrastructure to run the treatment at scale without deliberate investment.

MiracleFeet’s early detection and referral (EDR) programme addresses this by training the people most likely to see a newborn first, such as midwives, community health workers, and frontline care providers, to recognise clubfoot at birth, educate families, and create a direct pathway to the nearest treating clinic. The logic is simple: the earlier a child is identified, the wider the window for successful, non-surgical correction.
Data as the quiet force multiplier
The treatment itself is intentionally low-tech. Casting materials, a brace, a trained pair of hands. McCarthy is clear that he would not want a screen placed between a provider and a child’s foot. But the infrastructure around the treatment is where digital tools have earned their place.
MiracleFeet’s mobile data collection app, CAST, is deployed across hundreds of clinics worldwide, feeding real-time treatment data into Salesforce dashboards that provide visibility at clinic, country, and regional level. A small central team can monitor quality indicators, flag patients who have missed follow-up appointments, and identify clinics with higher relapse rates without waiting months for field reports.
“Data earns its place when it improves outcomes and efficiency,” McCarthy says. The organisation tracks six key treatment quality indicators across every clinic and country it supports. The brace and casting method may be low-tech. The oversight layer is not.
A redesigned, lower-cost brace has compounded the effect. The older models were expensive, often imported, and uncomfortable enough that children resisted wearing them at night. It was a serious problem since the brace holds the correction in place for years. Every night without it raises the relapse risk. The new design drives the cost down while improving wearability. At the scale MiracleFeet operates, that combination meaningfully shifts both the budget and the success rate.
What a ten-year-old in Guatemala changed
The numbers are important. The stories are why McCarthy keeps going.
During a recent visit to Guatemala, he met a mother whose first child had been treated for clubfoot and was running around the room with a ball as they spoke. She described how, in the worst days after her baby’s diagnosis, she had been told to accept it as fate. Within a week, she had found MiracleFeet; a clinic was fifteen minutes from her home and treatment was free. By the time McCarthy met her, she had become part of a parent support network, helping other families through the same fear she had once felt herself.
Before the visit ended, she mentioned a ten-year-old girl in a nearby village with untreated clubfoot whose mother had been told by someone that it was God’s will. The clinic representative asked for details. Within fifteen minutes, the group was in a van. When they returned, they brought news that the mother had agreed to schedule a clinic appointment because she had seen the result with her own eyes and heard it from another local mother.
That, in microcosm, is the system MiracleFeet is trying to build across Southeast Asia: not a parallel structure, but a self-reinforcing one, where treated families become advocates, communities become referral networks, and governments eventually build clubfoot care into routine health delivery because the evidence is simply too clear to ignore.
What has to happen next
The window is genuinely open. As incomes rise and infrastructure extends across Southeast Asia, the logistical barriers that have kept treatment out of rural communities for decades are beginning to come down. The philanthropic community in Singapore and across the region has shown real appetite for exactly this kind of high-leverage, systems-oriented intervention.

The obstacle is not proof of concept. MiracleFeet has that. It is not the cost of treatment. That has already been driven to a level where a single engaged donor or government partner can fund hundreds of children. The obstacle is the final distance between what works and every child who still needs it.
“I would ask readers to consider how much they would pay to make sure they themselves, their child, or a friend could walk for the rest of their life,” McCarthy says. “When this conversation becomes personal, it’s amazing how high that value goes.”
Eight million people did not get that conversation in time. The point of MiracleFeet’s push into Asia Pacific is to make sure the next generation does.
