A midsole assembly for an athletic shoe comprises an upper midsole 3a and a lower midsole 3b formed of soft elastic material, and a corrugated sheet 4 having a heel portion 4a formed with a corrugation. The corrugated sheet 4 is interposed between the upper and lower midsoles 3a, 3b. Upwardly and downwardly extending walls 6, 7 and 8 are formed at the medial and lateral sides of the corrugated sheet 4. Thereby, transverse or lateral deformation of the heel portion of the midsole 3 can be securely prevented and running stability can be further improved.
