Shoe insole

Abstract

To support a natural ideal walk and prevent various foot problems from occurring. The shoe insole (1) is provided with a support base plate (3) attached on the back face of a flexible front surface sheet (2) for the area at least from the calcaneal bone to the proximal phalanx of the bones of digits of a foot. The support base plate (3) is comprised of a back base plate (30) for the area from the calcaneal bone to the metatarsal bone and a front base plate (31) for the area from the metatarsal bone to the proximal phalanx of the bones of digits of the foot. A cut part (6) is formed at the area of the front base plate (31) for the metatarsophalangeal joint of the big toe.

Description

technical field [0001] The present invention relates to insoles used in footwear such as shoes and sandals, and more particularly to insoles that assist natural walking and can prevent foot injuries such as hallux valgus. Background technique [0002] Conventionally, insoles are laid on the insoles of shoes or sandals, and are used for the purpose of improving wearing comfort, such as improving ventilation. Based on such insoles, there are proposed insoles for improving health by providing protrusions on the surface to stimulate the soles of the feet, and orthotic and therapeutic insoles for correcting foot valgus and foot inversion by inclining the surface. [0003] In general, the movements of the body parts are divided into three main body planes, namely, the sagittal plane that divides the body into left and right halves, the frontal plane that divides the front and rear halves of the body, and the horizontal plane that divides the upper and lower halves of the body. to...

Problems solved by technology

[0005] However, because the gastrocnemius and soleus muscles are short and the joints of the feet are hard, especially in the case of a person whose big toe is difficult to bend, because the dorsiflexion of the big toe is strong during the above-mentioned (off-the-ground period), it is difficult to smoothly bend the big toe. Therefore, it is possible to impose a forced load on the plantar muscles, which may cause damage to hallux valgus, Achilles tendonitis, plantar aponeurosis, and hallux corns and calluses.

There are cases where the above-mentioned conventional insoles cannot solve this technical problem only by controlling the inclination of the foot seen from the frontal plane and the sagittal plane of the foot.
