The soles of sports shoes on the market are designed according to different sports types, such as basketball shoes, football shoes, running shoes and the like, and each sole has respective characteristics. However, currently, running shoes on the market are mainly designed for rubber runways or common road surfaces, and EVA soles specially arranged for running machines are not yet seen. Through searching, in Chinese patent application No. CN207355579U, named "a special shoe for treadmill fitness", a special shoe for treadmill fitness is disclosed, which comprises an upper and a sole. The sole adopts an anti-skid, breathable and massage structure, the upper is provided with two types of warmth-keeping and cool, and the sole and the upper are combined together by adopting side walls on the sole. In order to reduce the impact of gravity on feet and the vibration of jolt on brain during running, the sole is made of a high-elasticity rubber sheet with the thickness of 10-20 mm; too thick, unsafe when running, easy to break the feet and fall down; too thin, not playing a role in shock absorption; and the high-elasticity rubber sheet is easy to bend and resistant to bend, so that the plantar-toe joint part is easy to bend during running. In the Chinese patent of the utility model entitled "sports shoes for running machine", CN204070757U, a sports shoe for running machine is disclosed, comprising a vamp and a sole, the vamp comprises a palm portion and a heel portion, a telescopic elastic device is connected between the palm portion and the heel portion, a sandwich layer is arranged in the sole, an opening is arranged on the side surface of the sole in the sandwich layer, an opening zipper is arranged in the opening of the sandwich layer, and a detachable elastic middle pad is arranged in the sandwich layer.
The sole of the running machine in the above patent is not fully designed according to the characteristics of the running machine, for example, the sole in the grant publication CN207355579U mainly focuses on the massage of the sole, and although the high elastic rubber sheet with the thickness of 10-20mm is used as the sole, the stability of the sole can be improved to a certain extent, but the weight is heavy, and the burden of sports is increased. The athletic footwear of grant publication number CN204070757U provides an intermediate layer in the sole, complicating the sole structure and making it relatively cumbersome to manufacture and manufacture.
In view of this, the present inventors have conducted intensive studies on the above problems, and have produced the present utility model.
