An athletic shoe midsole assembly includes a midsole formed of soft elastic material and a corrugated sheet disposed in the heel portion of the midsole. The corrugated sheet has a pocket structure at edge areas of the sheet, for example the medial side edge, formed by two layers spaced apart from each other with a respective void pocket formed therebetween. Since the compressive hardness of the midsole is higher on the medial side including the pocket structure, transverse deformation of the shoe on landing can be prevented and over-pronation can be restrained on this medial side and the loss of athletic power can be decreased. On the other hand, flexibility of the midsole is maintained on the lateral side without a pocket structure and thus cushioning properties can be secured on this lateral side.
