Description

Sole with double-layer midsole structure Technical Field The present utility model relates to a method. Background The structural design of the sports sole directly influences the wearing experience and the sports performance, particularly the midsole is used as a core cushioning and supporting component, and the material selection and the configuration innovation are always important in industry. The traditional scheme has the technical bottlenecks that the single material cannot achieve both the supportability and the comfortableness, namely, the sole in early stage adopts single-density material (such as EVA or rubber), the high-hardness material can provide stable support, but has poor shock absorption capability, foot fatigue is easily caused, the low-hardness material (such as foamed EVA) can improve the comfortableness, but is easy to collapse and deform (the deformation amount can reach 20 percent) after long-term compression, and the sole fasciitis risk is increased due to lack of arch support. Disclosure of utility model The utility model aims to provide a sole structure capable of effectively improving comfort and support. In order to solve the problems, the utility model provides a sole with a double-layer midsole structure, which is characterized by comprising a midsole and an outsole, and is characterized in that: The insole comprises an outer frame, a filling body and an elastic support body, wherein the upper surface of the outer frame is provided with an inwards concave mounting groove at least at an arch part, the support body is made of an elastic material and is arranged at the bottom of the mounting groove, the filling body is positioned above the support body and fills the mounting groove, the elasticity of the filling body is smaller than that of the outer frame, and the hardness of the outer frame is greater than that of the filling body; the outsole is attached to the bottom of the outer frame, and a plurality of anti-skid blocks are arranged at the bottom of the outsole. As a further improvement of the utility model, the abdomen-filling body is a porous polymer formed by supercritical foaming technology of aromatic TPU. As a further improvement of the utility model, the outer frame is a porous polymer of araliphatic TPU formed by supercritical foaming technology. As a further improvement of the utility model, the support is a nylon plate. As a further improvement of the utility model, the outer frame is provided with a hollow area, and the hollow area is positioned at the bottom of the mounting groove and penetrates through the outer frame. The utility model has the beneficial effects that the middle sole is provided with the outer frame body and the abdomen filling body, the outer frame body and the abdomen filling body are in contact with the footsteps by adopting different hardness and elasticity, the foot feeling is softer and the elasticity is better, the comfortable foot feeling is provided, the outer frame body is harder, the better strength is provided, and the support body is arranged in the middle sole and has the elasticity, so that the support and the propelling force are provided for the foot.
