Insole device

The present invention relates to an insole, and more particularly to an insole device that can be placed on a foot of a human body.

Human beings are multi-joint skeleton structures in which both feet stand and walk. In addition to supporting the weight with both feet when standing, the pedaling or impulse during walking or running also requires the use of two-legged loads. The feet of each foot contain 26 bones, which are surrounded by complex and dense ligaments and fascia. The whole foot is like a bow-shaped structure. It has three important arches, namely the medial longitudinal arch and the lateral longitudinal. The bow, and the crossbow, provide the foot suspension function and withstand the pressure from the body weight for the human body to stand, walk, run and jump.

Wherein, the medial longitudinal arch of the foot is composed of calcaneus, talus, scaphoid, three wedge-shaped bones and three medial humerus, with talus as the cornerstone, with better softness and greater curvature. It is good for shock absorption. The lateral longitudinal arch is composed of the calcaneus, the tibia and the fourth and fifth metatarsal bones, and the tibia is the base stone. The lateral longitudinal arch is relatively flat and has little mobility, which is favorable for supporting. The crossbow generally refers to the base of the five shins in front of the sole of the foot.

According to the biomechanics of the foot, the human body stands with the first metatarsal root, the fifth metatarsal root and the calcaneus as the support points, which can be used to support the body weight. the amount. When walking, the ground pressure is first received by the calcaneus, and then moved from the fifth metatarsal to the first metatarsal from the outside of the foot, and then walked on. When running, the medial longitudinal arch between the first metatarsal and calcaneus provides moderate elasticity and torsion and absorbs the reaction of the ground to achieve shock absorption.

Usually, the manufacturer will lay a foot pad for the foot in a shoe to help the foot relieve stress. However, since the general insole is a soft cushion body, it only has a shock absorbing effect. When the human body stands and is placed on it, the insole is pressed into a flat shape, which cannot provide supporting force, and allows the arch to directly bear the weight of the human body. The pressure is easy to cause soreness in the arch area. When walking, the insole is pressed and pressed into a flat shape, and it is unable to stably exert a partial pressure support on the muscles of the arch part and the Yongquan point, and it is easy to cause soreness and strain on the muscle ligament of the arch part. The situation. After understanding the mechanics of the foot structure of the human body during static standing and dynamic walking, it can be seen that the existing insole must strengthen the supporting force and elasticity in a proper position, and can meet the user's needs.

Accordingly, it is an object of the present invention to provide an insole device that reduces foot pressure and increases comfort.

Thus, the novel insole device can be used for a foot of a human body and includes a pad body, a support base, a forefoot pad, and a heel pad.

The pad body includes a foot area at the bottom corresponding to one of the feet of the foot, a heel area corresponding to one of the heel of the foot, and an arch located between the foot area and the heel area Area.

The support base has a hardness greater than that of the pad body, is mounted on the arch region of the pad body and the heel region, and includes a middle support portion, an inner support portion disposed on the inner side of the middle support portion, and a An outer support portion on the outer side of the middle support portion, and a rear peripheral portion spaced apart from the rear side of the middle support portion and connected to the inner support portion and the outer support portion, the middle support portion, the inner support portion, and the rear support portion The outer struts cooperate with the rear rim to define a pocket, and the outer struts have a convex end that projects forwardly to one of the transverse arches of the foot.

The forefoot pad is softer than the pad body and is mounted on the palm area of the pad body.

The heel pad is softer than the pad body and is mounted in the heel region of the pad body and located in the receptacle of the support seat.
