Abstract: A sole structure for a sports shoe that controls bendability of a forefoot region of the sole structure. The sole structure includes an upper midsole disposed on an upper side of the forefoot region of the sports shoe and formed of a soft elastic material, a lower midsole disposed under the upper midsole and formed of a soft elastic material, and an outsole that is disposed on a lower surface of the lower midsole and that has sole bent grooves extending substantially in a sole width direction. Both the lower surface of the upper midsole and the upper surface of the lower midsole have corrugated mating surfaces that are formed of wavy shapes extending substantially in a sole longitudinal direction. Ridge lines and trough lines of the wavy shapes of the upper midsole extend substantially in the sole width direction. The ridge lines of the wavy shapes of the upper midsole of a relatively higher hardness are overlapped with the sole bent grooves of the outsole in a vertical direction.

Abstract: A sole structure for a shoe that can reduce the burden of MP joints and a knee joint of a shoe wearer's foot during running and that can improve cushioning properties. The sole structure of the shoe includes an upper plate of a hard elastic member disposed at a forefoot region of the shoe, a lower plate of a hard elastic member disposed under and spaced away from the upper plate, and a midsole of a soft elastic member interposed between the upper plate and the lower plate. The midsole has a longitudinally extending hollow portion that is upwardly concavely curved at a lateral mid-portion of the midsole. The lower plate has a concave portion corresponding to the hollow portion of the midsole.
