To add on, the materials have been set to consider the foot as a bony structure with Young's Modulus of 7.3GPa and Poisson Ratio of 0.3 (Isotropic Elsaticity) and the midsole to have a Young's Modulus of 1.2MPa and Poisson Ratio of 0.48 (Isotropic Elasticity). In theory, since the foot has a higher Young's Modulus value, it should cause the shoe sole to compress while suffering from minor deformation. However, some of the varied results I have obtained so far includes the midsole experiencing 0 total deformation while the foot experiences an abnormally high value for deformation, as seen in the picture below. For reference, the midsole thickness is merely 25mm.
