Development and evaluation of band-embedded laterally wedged insoles for people with genu varum

In this study, we developed and assessed band-embedded laterally wedged insoles designed to correct genu varum, a condition characterized by outwardly bent knees. The product was specifically developed to improve usability and wearability in both indoor and outdoor conditions, addressing the key limitations of existing correction products. The wedged insoles were integrated so the band could promote proper alignment by redistributing the body weight toward the medial side of the legs, thereby reducing knee strain. Through detailed testing, the band demonstrated an average reduction of 14.76% in the gap between the knees, indicating significant corrective efficacy. Among the three developed designs, the hooks-and-loop-based band appeared to be the most effective, achieving a 15.94% reduction in the gap between the knees and receiving the highest scores in user satisfaction regarding design, functionality, comfort, and ease of use. The use of breathable lightweight materials and a design that accommodates both barefoot and shod conditions ensures long-term comfort and practicality. This product provides a practical, versatile, and user-friendly solution for genu varum correction and a foundation for further advancements in corrective orthopedic design.
