• Aim– Develop systematic methodology to quantitatively
assess key properties of orthotic insole materials with regard to their practical use by people with diabetes.
• Relevance– Choosing suitable insole material is vital for effective
foot orthotic treatment.

Method
• Examined 7 types of orthotic materials.• With accommodation, cushioning, and control of
orthotic insoles in mind, we developed test methods for examining force reduction, compression, insole-skin friction, shear, and thermal comfort.
• We proposed a novel performance index that combines various material test results together to quantify overall performance of insole materials.

Results• Insole-sock interface has lower coefficient of
friction and shearing stress than insole-skin interface.
• Material brand and corresponding density and cell volume, as well as thickness, are closely associated with moisture absorption and thermal comfort.

Conclusion
• On basis of our proposed performance index, practitioners can better understand properties and performance of various insole materials, thus prescribing suitable orthotic insoles for patients with diabetic foot.
