FITASY Inc, a custom 3D-printed footwear company based in Indianapolis, has launched a single-shoe purchasing option aimed at people who only need a left or a right shoe, including prosthetic users. The move highlights how digital manufacturing, spatial AI and on-demand production can address a long-standing but often overlooked problem for amputees: being forced to buy a complete pair of shoes when only one is needed.
The development was reported by the Derry Journal and announced by FITASY through a PR Newswire release. The company says its new single-shoe option is available directly through FITASY’s website and is priced at exactly half the cost of a pair.
For prosthetic users, this is a practical accessibility issue. Many people who use a lower-limb prosthesis only require one functional shoe for the biological foot, depending on the design of the prosthetic foot, cosmetic cover or footwear interface. In conventional retail, they may still be required to purchase a full pair, leaving one shoe unused. This increases cost, creates waste and reinforces the reality that mainstream footwear systems are rarely designed around disability or limb difference.
FITASY’s approach is different because its shoes are produced on demand rather than through traditional mass manufacturing. The company says its system combines spatial AI, advanced imaging and digital light projection 3D printing to create custom-fit footwear from smartphone-based foot scans. Customers capture a 360-degree model of the foot in both weight-bearing and relaxed positions, and the company’s software generates a personalised fit profile based on individual foot morphology.
The single-shoe model is possible because on-demand 3D printing avoids the commercial problem of splitting conventional pairs. Traditional footwear companies typically manufacture and distribute shoes as paired inventory. Selling one shoe can leave an unsold opposite shoe, making the model difficult to scale. FITASY claims its digital workflow allows the company to produce only the shoe that is ordered, reducing inventory waste and making single-shoe purchasing commercially viable.
For the IMEA region, the development is relevant beyond footwear retail. It points to a wider shift in orthotics, prosthetics and assistive technology: products can increasingly be designed around individual anatomy, function and need rather than standardised sizing or assumptions about the “average” user. This is especially important for people with limb loss, diabetic foot risk, partial foot amputation, congenital limb difference or major left-right asymmetry.
Footwear has always been a critical part of prosthetic and orthotic outcomes. For lower-limb prosthetic users, shoes influence standing balance, prosthetic alignment, leg length, rollover, gait symmetry and comfort. A change in heel height, sole stiffness or shoe geometry can affect how a prosthesis performs. For people with diabetes or neuropathy, footwear fit can also affect pressure distribution, ulcer risk and long-term limb preservation.
FITASY’s announcement should therefore be seen as part of a broader digital-footwear movement. Custom-fit 3D-printed shoes may eventually create new opportunities for people who cannot be served well by standard sizes, including those with deformity, swelling, high-risk feet or complex orthotic needs. Digital footwear systems could also support more precise matching between the biological foot, prosthetic side, orthotic device and daily footwear.
The accessibility message is also important. The company’s launch directly challenges a market assumption that shoes must always be sold in pairs. For people with disabilities, this assumption can be expensive and exclusionary. A single-shoe option priced at half the cost of a pair is a simple but meaningful example of inclusive design: the product model changes to fit the user, instead of forcing the user to fit the product model.
One prosthetic user quoted in coverage of the launch described the previous experience as both costly and wasteful, saying that using an artificial walking prosthesis meant only one shoe was needed, yet a full pair still had to be purchased for years. The user described FITASY’s model as an example of what becomes possible when shoes are designed for real people with real needs rather than only for the average customer.
For clinicians and O&P providers, the development raises practical questions. Could single-shoe purchasing become more common for prosthetic users? Could digital footwear platforms integrate with prosthetic and orthotic clinics? Could 3D-printed footwear be adapted for orthotic insoles, partial foot prostheses, diabetic footwear or shoe modifications? And how should clinicians assess durability, pressure, safety and long-term performance before recommending such products?
These questions are especially relevant in the Middle East, Africa and South Asia, where prosthetic users may face high device costs, limited follow-up services and restricted access to specialist footwear. A digital, on-demand footwear model could have value if it can be made affordable, durable, clinically appropriate and accessible across different markets. However, it should be integrated carefully with professional assessment, especially for users with neuropathy, wounds, balance problems or complex gait needs.
For the O&P sector, FITASY’s launch reinforces several wider trends:
The move also connects with sustainability. In conventional systems, unused shoes can become unnecessary waste. For prosthetic users who repeatedly buy pairs and discard one side, the environmental and financial burden accumulates over time. Digital manufacturing offers a potential alternative by producing only what is needed.
For IMEA CPO readers, the key lesson is that innovation in rehabilitation does not always need to be a complex robotic system or high-end prosthetic component. Sometimes it is a change in the supply model that removes a daily inconvenience, reduces cost and improves dignity for users. FITASY’s single-shoe option is a reminder that inclusive technology begins with listening to people whose needs are not met by standard products.
As AI and 3D printing continue to enter footwear, prosthetics and orthotics, the next opportunity will be clinical integration. The strongest future models may combine digital foot capture, custom footwear, orthotic design, prosthetic alignment considerations and pressure-aware fitting into one connected workflow. For prosthetic users, that could mean footwear that is not only easier to buy, but better suited to how they actually move.
