Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shoe sole, concretely is a shoe sole structure with arch support. BACKGROUND

[0002] The arch can effectively buffer the ground impact force when walking or running, protect the foot and leg joints, the arch structure can protect the foot blood vessels and nerves from compression, maintain normal blood circulation and nerve conduction, but when high-intensity exercise, the arch is stressed, easy to easily cause plantar fasciitis or tibial stress syndrome, therefore the existing shoe sole all sets up the arc-shaped protrusion to support the arch position.

[0003] Through the search, the application book with patent application No. 202420214427.0 discloses a 3D printing arch support structure, which comprises a shoe sole and a support member, the support member is installed at the arch of the shoe sole, wherein the support member comprises a frame and a lattice structure, the lattice structure is formed by stacking a plurality of hollow polygonal components and is connected to the frame on the side, the frame is installed on both sides of the arch of the shoe sole, and the lattice structure is installed on the plane of the arch of the shoe sole.

[0004] Although the 3D printing arch support structure can effectively balance the inner and outer sides of the shoe sole and provide sufficient arch support by the frame on the support member pressing against both sides of the arch, the shoe sole part of the 3D printing arch support structure is not provided with an effective shock absorption structure. During daily walking, exercise and other activities, the impact force generated by the human foot and the ground cannot be reasonably buffered and dispersed. Especially at the arch position, due to the lack of protection of the shock absorption structure, a large proportion of impact force is borne. As an important load-bearing and buffering structure of the human body, the arch is prone to discomfort at the arch position due to long-term bearing of excessive impact force. Such discomfort not only affects the wearer's current walking experience and comfort, but also may cause damage to the arch structure over time, such as causing plantar fasciitis and other diseases, which poses a potential threat to the health of the human foot.

[0005] Therefore, we propose a shoe sole structure with arch support. UTILITY MODEL CONTENT

[0006] In view of the deficiencies of the prior art, the utility model provides a shoe sole structure with arch support, which solves the problem that the existing device does not set a shock absorption structure on the shoe sole, resulting in a large impact force on the arch, which easily causes arch discomfort.

[0007] To achieve the above purpose, the utility model realizes the following technical scheme: a shoe sole structure with arch support, comprising an outsole, the inside of the outsole is provided with a midsole;

[0008] The midsole is bonded to the bottom surface inside the outsole. A shock-absorbing pad is bonded to the top surface of the outsole. An arc-shaped protrusion is provided on the top surface of the shock-absorbing pad at a position corresponding to the arch of the foot. A support pad is provided at the bottom of the arc-shaped protrusion. A first shock-absorbing pad and a second shock-absorbing pad are bonded to the front and back sides of the bottom surface of the shock-absorbing pad, respectively.

[0009] Preferably, the front and rear sides of the top surface of the bottom are respectively provided with a first groove and a second groove corresponding to the positions of the first shock-absorbing pad and the second shock-absorbing pad. The first shock-absorbing pad and the second shock-absorbing pad are respectively adhered to the inside of the first shock-absorbing pad and the second groove, wherein the first shock-absorbing pad and the second shock-absorbing pad are respectively housed by the first groove and the second groove.

[0010] Preferably, both the first and second shock-absorbing pads are air cushions. The first shock-absorbing pad is circular, the side of the second shock-absorbing pad closest to the toe is semi-circular, and the side of the second shock-absorbing pad furthest from the toe is rectangular. The air cushion can effectively attenuate the ground reaction force and reduce the vertical impact on the foot.

[0011] Preferably, the cushioning pad is made of foam, the midsole is made of PU, and the cushioning pad is made of TPU. The foam is lightweight and soft, and its porous structure allows for rapid sweat absorption, keeping the feet dry and increasing foot comfort. The PU material can increase the rebound effect of the sole.

[0012] Preferably, the support pad includes a support plate and an arc-shaped support portion. The support plate is bonded to the bottom surface of the shock-absorbing pad. An arc-shaped support portion is provided on the top surface of the support plate near the arc-shaped protrusion. The arc-shaped support portion is in contact with the bottom surface of the arc-shaped protrusion. Both the support plate and the arc-shaped support portion are made of carbon fiber. The support plate supports the arc-shaped protrusion to prevent it from collapsing, thereby providing stable support for the arch of the foot.

[0013] Preferably, the bottom surface of the outsole has anti-slip grooves arranged in a linear array, and the cross-section of the anti-slip grooves is semi-circular. The anti-slip grooves can increase the friction between the outsole and the ground.

[0014] This invention provides a shoe sole structure with arch support. It has the following beneficial effects:

[0015] This outsole structure with arch support provides support to the wearer's arch through support pads and curved protrusions. The support plate prevents the curved protrusions from collapsing, thus providing stable support to the arch. A first shock-absorbing pad cushions the heel, and a second shock-absorbing pad cushions the forefoot. The midsole, in conjunction with the first and second shock-absorbing pads, provides cushioning and rebound, thereby reducing the impact on the arch. The shock-absorbing pads also allow for rapid sweat absorption, keeping the feet dry and improving the wearing experience and comfort. This design solves the problem of existing devices lacking a cushioning structure in the outsole, which leads to excessive impact on the arch and discomfort. Attached Figure Description
