Description

Functional insole

Technical Field

The utility model relates to the field of insoles, in particular to a functional insole.

Background

Due to the fact that people walk on flat ground for a long time, the foot using environment is single, and the foot posture is wrong, the probability that people suffer from foot deformity is higher and higher. Most of the foot deformities involve arch deformities, i.e., high or low arches. Aiming at a patient with arch deformity, the conventional treatment scheme is to wear a functional insole to adjust the stress condition of the foot of the patient, further adjust the force applying posture of the foot of the patient and finally slowly improve the arch deformity condition.

However, there are two kinds of conventional functional insoles in the market, and one kind of functional insole is a functional insole with a hard material in the whole body. Such insoles provide good strength support to the foot, but the flexibility of the user's foot is affected during exercise due to the hardness of the insole. The whole body of the corresponding functional insole is made of flexible materials, the flexibility of the foot of a user cannot be influenced in the using process of the insole, but the soft texture reduces the supporting force of the insole on the foot and influences the performance of the functional insole.

Taking the example of the arch of foot being too high, making a functional insole corresponding to the arch of foot requires the insole to be raised corresponding to the arch of foot supporting part of the arch of foot for providing supporting force to the arch of foot, and because the raised arch of foot supporting part is higher, the insole made of hard material is hard and heavy, thus seriously affecting the normal use of the patient. If the insole is made of soft materials, the arch support part can not provide enough support force to the arch part of the foot, and the expected auxiliary treatment effect can not be achieved.

Therefore, the research and development of a functional insole with high hardness and moderate softness of the arch support part is an urgent need of the foot rehabilitation treatment market.

The lattice-filling structure may provide some support to the arch contact surface while being resilient. The latticed filling structure can also be directly designed into a whole at the beginning of the design of the insole body, and is realized by 3D printing. Of course the filling structure can also be filled with other light materials.

Preferably, the heel support surface and the bottom surface of the insole form a second cavity. The second cavity can reduce the use of materials of the foot root part of the insole, reduce the weight of the insole and increase the flexibility of the foot root supporting part of the insole.

Preferably, a support portion is provided between the heel support surface and the bottom surface of the second cavity. The second cavity ensures the flexibility of the heel supporting surface of the insole, and the supporting part ensures the supporting force of the heel supporting surface.

Preferably, the bottom surface corresponding to the heel supporting surface is recessed upwards to form a cushion accommodating cavity, and the cushion is sleeved in the accommodating cavity. The cushion air cushion can provide cushioning force for the heel in the use process of the insole, and the impact of the heel on the heel in the walking process is reduced.

Preferably, the sweat absorbing layer is bonded and fixed above the sole attaching surface. The sweat absorbing layer can absorb sweat stain and keep the sole dry.

Preferably, the sweat absorbing layer is a hypo-absorbent material. The Haiboli material is environment-friendly high-polymer cotton, is prepared by crushing PU Foam into powder, adding PU raw material, processing by nanotechnology, and polymerizing by advanced equipment and formula, has the characteristics of air permeability, moisture absorption, antibiosis, deodorization, buffering, shock absorption, environmental protection, light weight and the like, can be added with special functional materials such as mildew-proof antibacterial agents, spices, activated carbon, cork dust, antistatic materials and the like, and has corresponding effects.

Preferably, the sweat-absorbing layer also can be directly printed and formed with the shoe-pad body an organic whole through 3D printing technique, and such structure makes the finished product more firmly durable.

Preferably, the sweat absorbing layer covers the plantar-facing surface and extends to the toes.

The utility model has the beneficial effects that: the light insole provides proper strength in the area needing strong support, and meanwhile, the insole has a simple structure and low manufacturing cost, and is suitable for large-scale popularization and use.
