Description

Technical Field

[0001] The invention relates to the technical field of shoe materials, and in particular to a high-elastic and high-durability running shoe sole and a manufacturing process thereof. Background Art

[0002] Marathon is a long-distance running sport. If you don’t have a pair of suitable running shoes, the impact on the runner’s knees will be great, which can easily cause damage and is not conducive to runners achieving good results. At present, the soles of running shoes are mostly divided into two layers: the outsole and the midsole. The midsole is close to the side of the foot. The midsole is often made of elastic flexible materials that are injection molded in one piece. The flexibility is used to absorb the impact force during exercise, thereby reducing the impact of the impact force on the foot, but it will affect the support and stability of the sole; the outsole is the one that rubs and contacts the ground. The outsole is generally made of rubber and has high grip performance. Most running shoes have a support structure added to the sole. Although it can improve the support of the sole, it will affect comfort. In addition, because long-distance running will cause the temperature of the sole material to rise, the physical properties of the material will deteriorate, and the durability will be difficult to meet the needs of long-distance running. Summary of the invention

[0011] The elastic support member is provided with side wings on the inner side and / or the outer side corresponding to the human body heel, and the side wings are extended from the elastic support member toward the human body heel.

[0012] The arc-shaped covering piece includes a first arc-shaped covering piece and a second arc-shaped covering piece arranged along the width direction of the shoe outsole. The first arc-shaped covering piece and the second arc-shaped covering piece are connected to form recessed parts at the front and rear ends of the arc-shaped covering piece.

[0013] The outsole includes a first large bottom plate arranged corresponding to the forefoot of a human body and a second large bottom plate arranged corresponding to the heel of a human body, the front end of the first large bottom plate is upwardly curled and fits with the front end of the midsole, the rear end of the first large bottom plate is adapted to the shape of the arc-shaped covering part, and the front end of the second large bottom plate is open and the middle part is a hollow structure.

[0014] A manufacturing process for a high-elastic and high-durability running shoe sole comprises the following steps: Step 1: First, an elastic support member is formed by a mold; Step 2, then putting the elastic support member into the midsole injection mold, pouring the midsole liquid material, and obtaining the shoe midsole with the elastic support member embedded therein after injection molding; Step 3, then forming an integrally formed cushioning foam through a mold; Step 4, then putting the cushioning foam into the outsole forming mold, pouring the outsole liquid material, and forming to obtain the shoe outsole covered with the cushioning foam; Step 5: Finally, the midsole and the outsole are bonded together to obtain the high-elastic and high-durability running shoe sole.
