Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insoles, in particular to a double-layer shock-absorbing insole. Background Art
[0002] Double-layer shock-absorbing insoles are typically made of two different layers of material to provide improved cushioning and comfort. They are designed to absorb shock more effectively, reducing pressure on the foot and leg, thereby reducing the risk of injury and improving comfort when standing or walking for long periods of time.
[0003] Traditional double-layer shock-absorbing insoles are similar in structure to single-layer shock-absorbing insoles, differing primarily in their construction and material combination. Double-layer insoles typically consist of a support layer at the bottom and a cushioning layer at the top. This design provides additional cushioning while maintaining foot stability. For example, some double-layer shock-absorbing insoles use a harder material at the bottom for support and a softer material at the top for added comfort and cushioning. However, since the cushioning effect of these double-layer shock-absorbing insoles primarily relies on the cushioning layer, the cushioning effect is insignificant unless the cushioning material is thick.
[0004] In order to provide additional elasticity and support and enhance the shock-absorbing performance of the insole, it is necessary to improve and optimize the shock-absorbing structure of the insole, especially the shock-absorbing structure of the heel. Utility Model Content
[0005] In response to the shortcomings of the prior art, the present invention provides a double-layer shock-absorbing insole that more effectively absorbs shock, reduces pressure on the feet and legs, thereby reducing the risk of injury and improving comfort during prolonged standing or walking. It also provides improved arch support, which is particularly beneficial for people with flat or high-arched feet. When used in corrective insoles, it can also improve foot alignment and distribute pressure.
[0006] The technical solution of the present invention is: a double-layer shock-absorbing insole, including a shock-absorbing body, characterized in that: the shock-absorbing body includes a first arch portion and a second arch portion with two ends interlocked with each other, the middle portions of the first arch portion and the second arch portion are respectively arched outward, and a deformation space is formed between the first arch portion and the second arch portion.
[0007] Preferably, the deformation space formed between the first arched portion and the second arched portion can also be sandwiched with an auxiliary shock-absorbing structure such as an air bag or a shock-absorbing sheet, so that the user can adjust and change it according to the actual needs of his weight or exercise volume, thereby improving versatility and flexibility.
[0008] Preferably, the double-layer shock-absorbing insole further includes an insole body, and the shock-absorbing body is arranged at the bottom of the insole body.
[0009] Preferably, the shock-absorbing body extends from the heel of the bottom of the insole body to the arch of the foot.
[0010] Preferably, the shock absorber is formed by laminating a first arch portion and a second arch portion together, or the shock absorber is an integrally formed structure, or the shock absorber is formed by bending and pressing sheets.
[0011] Preferably, one end of the shock-absorbing body is further provided with an extension portion so as to be connected to the insole body, the sole, etc.
[0012] The beneficial effects of the present invention are as follows: the shock-absorbing body formed by the interlocking first and second arched portions at both ends can more effectively absorb shock, reduce pressure on the feet and legs, thereby reducing the risk of injury, and improve comfort during prolonged standing or walking. It also provides better arch support, which is particularly beneficial for people with flat or high-arched feet. When used in corrective insoles, it can also improve foot alignment and distribute pressure. BRIEF DESCRIPTION OF THE DRAWINGS
