These characteristics are particularly interesting in running shoes for professional usage. Despite the huge potential of this type of midsoles, the literature reveals that relatively little is known about cushioning properties towards lattice structures in footwear design. Consequently, this research aims to narrow this research gap and perform an objective and subjective research into the discomfort perceptions towards the 3D-printing midsoles. To this aim, cushioning properties of lattice structures printed with SLS-printed have been simulated with finite elements and tested with an impact tester. From the different options of lattice structures, two different typologies have been selected for the fabrication of two pair of shoe prototypes. Moreover, a subjective test will be performed among runners in order to compare the discomfort perception differences between the different prototypes.
