Abstract
An athletic shoe comprises an upper (3) for accommodating an instep of a foot, and outer sole (4) having a tread on bottom surface, and a midsole (1) interposed between the upper (3) and the outer sole (4). A shock absorbing groove (2) is formed in the midsole (1). The shock absorbing groove (2) is formed of a long transverse groove (20) and a short longitudinal groove (21) in a continuous manner. The transverse groove (20) is formed on the midsole (1) extending from a side face of a rear foot part (1B) of the midsole (1) on lateral side (10) of the foot to a back face of a heel part (1H) of the midsole (1) and has an end (22) on the heel part (1H). The longitudinal groove (21) is formed in such a manner as to cut out the heel part (1H) of the midsole (1) from a lower end face of the midsole (1) toward the end of the transverse groove (20).
