Abstract: A shoe midsole having a structure formed by additive manufacturing process, including a bottom pad, an upper pad and a shock-absorbing layer. The bottom pad has foot-shaped profile and includes a plurality of stress zones. The upper pad is arranged opposite to the bottom pad and has foot-shaped profile almost identical to that of the bottom pad. The shock-absorbing layer is arranged between the bottom pad and the upper pad and includes a plurality of pressure-bearing units. The pressure-bearing unit is arranged between the bottom pad and the upper pad in the manner that two ends of each pressure-bearing unit abut against the bottom pad and the upper pad respectively. The pressure-bearing unit has excellent mechanical properties such as higher energy absorption and force bearing capacity for bearing pressures or stress put by the foot, good flexibility and higher deflection capacity that can be elastically deformed in the longitudinal direction.
