Running shoe sole

Abstract

The invention relates to a shoe sole, and provides a running shoe sole which can effectively prevent the feet from being injured, has the excellent damping and boosting actions and is suitable for manufacture of exercise running shoes. The running shoe sole comprises a large sole body and a middle sole body arranged on the large sole body, and the lower surface of the middle sole body is provided with a toe air cushion, a phalanx air cushion and a heel air cushion which correspond to a toe area, a phalanx area and a heel area of the foot respectively; the upper surface of the large sole body is provided with a containing groove used for containing the middle sole body, the lower surface of the toe air cushion, the lower surface of the phalanx air cushion and the lower surface of the heel air cushion jointly form a contact face used for allowing the middle sole body to make contact with the groove bottom of the containing groove, and the bottom face of the middle sole body is far away from the groove bottom of the containing groove; the lower surface of the large sole body is provided with ground-gripping patterns.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a running shoe sole. Background technique [0002] As we all know, in the process of walking or running, the feet will receive a very large impact force from the ground feedback, which is easy to cause damage to the feet. For this reason, people try their best to slow down this impact force when designing shoes, especially soles. At present, the commonly used method is to set the sole as follows: the sole is divided into two layers, the outsole and the midsole. The outsole is in contact with the ground and has high wear resistance; Side) is equipped with a midsole, the midsole is made of flexible material, and the flexibility is used to absorb the above-mentioned impact force, so as to reduce the impact of the impact force on the foot. However, the soft midsole directly absorbs the pedaling pressure without corresponding stress compensation. If it cannot provide walking assistance, it will increa...

At present, the commonly used method is to set the sole as follows: the sole is divided into two layers: the outsole and the midsole. The outsole is in contact with the ground and has high wear resistance; Side) is equipped with a midsole, the midsole is made of flexible material, and the flexibility is used to absorb the above-mentioned impact force, so as to reduce the impact of the impact force on the foot. However, the soft midsole directly absorbs the pedaling pressure without generating corresponding stress compensation. It cannot provide walking assistance, it will increase the burden of walking, increase the degree of exercise fatigue, is not conducive to exercise, is not suitable as the sole of running shoes, and has low practicability
