Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shoe soles, and in particular relates to an improved shoe sole structure. Background Art
[0002] The sole refers to the bottom part of the shoe, the part that directly contacts the ground. It is an important component of the shoe and plays a role in protecting the foot, providing support and grip.
[0003] Most of the existing soles are composed of three parts: the outsole, the midsole and the insole. When worn, the outsole is relatively hard, and the midsole will produce friction when in contact with the outsole, resulting in abnormal noise, while the comfort and softness of the insole will affect the wearing feel. In addition, when the sole is worn, the support for the heel depends only on the material of the sole itself. When the material is relatively soft for comfort, the support for the heel of the human body will be poor. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the outsole of the existing shoe is relatively hard during wearing, the friction of the midsole will produce abnormal noise, the comfort and softness of the insole affect the foot feel, and the heel cannot be supported while ensuring softness.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: an improved sole structure, including a sole, which is composed of an outsole, a midsole and an insole from bottom to top, a first flocking layer adhered to the top of the outsole through a first adhesive layer, and a second flocking layer is adhered to the outer side of the midsole and the insole through a second adhesive layer; a fixing groove is provided in the middle of the outsole located at the heel of a human body, a first air bag is provided inside the fixing groove, and a positioning groove connected to the first air bag is provided below the midsole at the first air bag; a bite groove is provided on the outer edge of the outer part of the outsole located at the heel of a human body, and a second air bag is provided inside the bite groove.
[0006] As an improvement, the first flocking layer and the second flocking layer are made of the same material, and are both made of cloth flock or leather flock.
[0007] As an improvement, the first bonding layer and the second bonding layer are made of the same material, and both are flocking adhesives.
[0008] As an improvement, the shapes of the fixing groove and the positioning groove match each other and are both elliptical structures.
[0009] As an improvement, the first airbag is a columnar structure, and the shape of the first airbag matches that of the fixing groove, the depth of the fixing groove is the same as 2 / 3 of the height of the first airbag, and the depth of the positioning groove is 1 / 3 of the height of the first airbag.
[0010] As an improvement, the second airbag is a U-shaped structure as a whole that matches the shape of the rear of the shoe outsole, and a plurality of engaging teeth that match the shape of the engaging groove are arranged above the second airbag.
[0011] The advantages of the utility model compared with the prior art are:
[0012] 1. The sole structure reduces the hardness of the outsole by flocking on the side where the outsole contacts the midsole, and flocks on the upper and lower sides of the midsole to reduce the friction between the outsole and the abnormal noise when wearing. The insole also increases the foot feel by flocking on the upper and lower sides of the insole.
[0013] 2. This sole structure reduces the difference in support provided by the materials of the outsole and the midsole on the heel of a human body by setting a first air bag at the heel of the human body, thereby increasing the strength of support, and provides support for the edge of the heel through a second air bag set externally.
