Stepping into the Future: Transforming Footwear Comfort and Performance with Personalised 3D-Printed Insoles and Midsoles

Advanced 3D printing is revolutionising orthotic therapy by enabling footwear solutions precisely tailored to an individual’s anatomy and biomechanics. Unlike traditional prefabricated or labour-intensive custom devices, these technologies use foot scans, pressure mapping, and gait analysis to produce insoles and midsoles that match unique foot geometry and pressure distribution. This precision allows for improved comfort, targeted offloading, and enhanced performance.

The presentation will review clinical applications across diabetic foot care, plantar fasciitis, arthritis management, and sports performance. Evidence shows that personalised 3D-printed insoles can reduce high-risk pressure areas, modify gait biomechanics, and even enhance energy return and impact absorption in athletes. Case studies will illustrate both therapeutic benefits and performance gains, highlighting how lattice structures and tuned midsole designs deliver measurable outcomes.

Participants will also gain an overview of the main 3D printing technologies used in footwear—FDM, SLS/MJF, DLP, and PolyJet—along with insights into the personalised design process. Future developments, including new materials, AI-driven design, and improved accessibility, will be discussed, outlining how these innovations are set to expand the clinical and performance potential of personalised orthotics in routine practice.
