The foot is divided into five parts: arch, instep, medial instep, lateral instep, and sole.

Foot structure consists of the human foot is made up of bones, muscles, blood vessels, nerves and other organizations.

The bones of the foot are connected into an arch-like structure called the arch, along the longitudinal called the longitudinal arch, along the transverse called the transverse arch is also known as the last of the inner pocket side, the forefoot of the ground part, the bottom of the heart of the concave part and the waist fossa part up to the heel of the heart of the part of the last is the last of the focus of the toes of the circumference, the waist circumference of the part, but also a direct relationship to the wearing of the part of the comfort.

There are two longitudinal arches of the foot: the one on the inner side of the foot is called the inner longitudinal arch, which is made up of the heel bone, the dice bone and the fourth and fifth foot bones. There are two transverse arches: the front transverse arch and the back transverse arch, the front transverse arch is composed of the first to fifth toe joints, that is, the last's forefoot landing part, the first toe to the fifth toe part, the last's forefoot part, the forefoot convex size, the bottom of the heart of the concavity design whether to comply with the part of the foot type law and adapt to the part of the arch change law, directly related to the comfort of wearing.

Each side of the foot has 26 bones, divided into tarsus, metatarsus and phalanges 3 groups. There are as many as dozens of joints in the foot.

Bones of the Foot

Tarsal Bones Located in the back half of the foot, they include the heel bone, talus, navicular, first cuneiform, second cuneiform, third cuneiform, and the dice bone,**** 7 pieces.

2. The metatarsal bones are located in the middle part of the foot, ***5 pieces. From inside to outside, they are called the first metatarsal, the second metatarsal, the third metatarsal, the fourth metatarsal and the fifth metatarsal. Each metatarsal is divided into three parts: the base (near the heel), the body and the head (near the toe). The first metatarsal has a metatarsal tubercle below its base, and the fifth metatarsal has a papillary protuberance called the fifth metatarsal tubercle (located in the middle of the lateral side of the foot) on the lateral side of its base.

3. There are 14 phalanges*** including 2 bunions (proximal phalanx and distal phalanx).

Joints of the foot

The lower end of the tibiofibula and the talus of the lower leg form the ankle joint, the largest joint of the foot and the joint of the rearmost part of the foot. Joints are formed between the tarsal bones and between the tarsal and metatarsal bones. The metatarsophalangeal joint is formed between the metatarsals and the phalanges, and the interphalangeal joint is formed between the phalanges and the phalanges. The second through fifth toes may be referred to as the proximal and distal interphalangeal joints. Regardless of the size of the joint, the range of motion and direction, its basic structure should include the articular surface, the joint capsule and the joint cavity of the three parts, are ligaments to strengthen its stability.

Expanded Information

The feet have a number of nerve reflex points connected to the heart, stomach, waist, and pelvic organs, etc. Stimulating these nerve reflex points improves the blood flow to the feet, which significantly promotes the treatment of diseases, and also has an excellent effect on health and beauty. Since the nerve reflex points on the feet are stimulated during walking, either negligent walking, incorrect pace, or defective shape of the toes, inner arches, or heels, which do not give full play to the functions of the feet, will bring obstacles to health.

Also look at the circulation. The circulation of arterial blood is carried out by the action of heart pressure, which occurs at the end of the blood vessels through the phenomenon of capillaries. Surface blood circulation is dependent on the role of the muscles, the movement of the feet play a great influence on the role of the muscles. Therefore, the foot is an extremely important organ for human health. Insufficient venous blood return to the feet will cause the accumulation of local acidic metabolic waste, this metabolic waste will cause fatigue, heavy feeling of the feet, if concentrated on the joints, will cause neuralgia, rheumatism, arthritis and other diseases.

If the blood circulation of the feet becomes bad, the organs that are directly damaged are the kidneys. When the kidneys are diseased, a painful sensation is produced on the inside below the knee or below the front, and when the front head of the heel is pressed, pain is felt. In addition, the muscles of the heel and the rectum harden and the muscles lose their elasticity, which is also a cause of constipation.
