In the framework of environmentally friendly processes and products, poly lactic acid(PLA) represents the best polymeric substitutes for various petropolymers because of its renewability, biodegradability, biocompatibility and good thermomechanical properties . The purpose of this study was to analyze foot pressure distribution of PLA materials in functional shoes. Comfort is an important aspect in footwear. Footwear comfort has an influence on injury [2, 3]. The development of new materials is considered as the important point for manufacturing functional shoes .
Ten healthy female(mean height: 159.8 cm, mean body mass: 54.8 kg, mean age 20.8 yrs.) participated in this study. All subjects were free of lower extremity pain, history of serious injuries or operative treatment, or subjective symptoms interfering with walking.
