Evidence behind the design
ZeroSole has been evaluated through laboratory testing and clinical evaluation, examining pressure distribution, targeted offloading, and its practical use for painful plantar foot lesions.
Laboratory testing
ZeroSole was tested in collaboration with the Assistive Technologies Innovation Centre (ATiC) to assess pressure redistribution across the foot and the effect of creating targeted offloading by removing individual cells.
The results show that customising ZeroSole to create an offloading cavity can reduce pressure at the targeted area. The study also found reduced plantar forces, supporting the insole's cushioning effect.
Clinical testing
A six-week clinical evaluation assessed the practical use of ZeroSole as an offloading treatment alongside usual care for painful plantar foot lesions, including corns and calluses.
Participants had their ZeroSole insoles customised to create an offloading cavity beneath their painful lesion. Pain was assessed before and after using the customised insoles, with lesion size also measured over the six-week evaluation period.
ZeroSole immediately reduced pain from plantar corns and calluses and improved overall comfort compared with the shoe's regular insole.
Following podiatry debridement, the evaluation found clinically significant lesion-size reduction over time when wearing ZeroSole for six weeks.
Backed by research from leading bodies
ZeroSole combines clinical experience, modular design and evidence-led pressure reduction to provide a practical approach to targeted offloading.
