A penetrating tunnel midsole structure of a Masai walking shoe includes a midsole(20) and a spring shank. The midsole is made of any one of polyester and polyurethane having a solidity of 40-60 and forms an arc shape of a convex curved surface from the front portion to the rear portion. The inclination angle of the heel of the midsole is 25-45degrees. Plural penetrating tunnels(22) are integrally formed with the midsole. Plural upper and lower protrusions(24,26) between the penetrating tunnels are integrally formed with the midsole.
