Sole and shoes with push-in shock-absorbing systemTechnical Field
The present invention relates to a sole with a push-in shock absorbing system and a shoe employing the sole.
Background
Sports shoes such as marathon running shoes are required to be lightweight and have good support and rebound properties to reduce the burden imposed on the shoes during long running. Lightweight and flexible soles, generally having relatively poor support and rebound properties, are difficult to form an efficient driving force by rebound of the sole. Therefore, shoes are available in the market, and a pushing support sheet for enhancing the supporting performance and the rebound resilience performance is added into the midsole, and the pushing support sheet is made of a material with better supporting performance than the midsole, so that the supporting performance and the rebound resilience performance of the sole are compensated, and the pushing of the foot can be more effectively assisted. The shape of the conventional propulsion support piece 10 is as shown in fig. 4, the outer contour of the propulsion support piece is basically the same as that of the upper surface of the midsole, the part in the outer contour is a solid structure, and the propulsion support piece 10 is installed between the midsole and the outsole when assembled. Although the pushing support piece 10 has a good support effect, the whole sole is stiff due to the pushing support piece 10, and particularly, when the heel part or the half sole of the sole is grounded, the sole is difficult to shock-absorbing smoothly.
In view of this, the present inventors have conducted intensive studies on the above problems, and have made the present invention.
