Since the foot is a soft organism, its dimensional change is large. In different postures such as lifting the foot, sitting, standing and exercising, even if the same part, the measured size is different.

The size of the foot after exercise is larger than that when standing before exercise, and the size of the standing time is larger than that when sitting still, and the size when sitting still is larger than the size of the lifting foot (foot hanging). From the size of the foot (that is, when the foot is suspended) to the size of the foot after the movement, the growth of the foot length is 10.5mm for men and 7.8mm for women; the growth of the circumference is 13.5mm for males and 16.4mm for females. 9.5mm, female 12mm; the growth of pockets is 8mm for men and 10.9mm for women. It is not difficult to see that the difference in measurement posture has a great influence on the measurement results.

People wear shoes not only to protect their feet from external injuries, but more importantly, to enable people to have plenty of energy to work and work. When people wear shoes, their feet are in motion, that is, the feet are in the largest size: wearing shoes. The measurement of the foot shape in our country is carried out by using the standing posture. It is close to the size of the movement, and the size is stable and easy to operate.

Two: the part of the measurement

The shape of the foot is a very irregular curved entity. The selection of the measurement site must be based on the actual needs of the shoes and shoes, and the main features that have the greatest impact on the wear are measured. The measurement site and its function are briefly described below.

(1) The length of the circumference of the toe joint around the metatarsophalangeal joint is called the circumference of the toe joint, also known as the circumference of the toe or the circumference of the toe. It is the main indicator for determining the fatness of the foot and is a very important size evaluation standard for shoes and shoes.

(2) The circumference of the anterior tibial circumference around the anterior tibial protrusion of the foot is called the anterior tibial circumference. This part plays an important role in the design of the last and the upper.

(3) The circumference of the boat and the circumference of the heel are measured around the bend point of the boat and the heel measured by the heel, referred to as the pocket or the pocket. It is an indispensable size for designing high-waist shoes and boots.

(4) The circumference of the ankle is the circumference measured around the thinnest part of the ankle. It is mainly used for the design of high-waist shoes and boots.

(5) The circumference of the calf is the circumference measured around the calf, mainly used for the design of the boots.

(6) The length of the knee circumference measured around the lower edge of the knee is called the knee length, mainly used for the design of the boots.

(7) The height of the knee under the knee is the height of the knee from the ground. It is an auxiliary size that determines the position of the knee under the circumference and is mainly used for the design of the boots.

(8) The height of the calf height from the long part of the calf to the ground at the bottom of the foot is called the height of the calf. It measures the circumference of the calf and is used for the design of the boots.

(9) Ankle height The height of the ankle length from the ground is called the ankle height. It is an auxiliary size that determines the position of the ankle length and is mainly used for the design of high waist shoes and boots.

(10) The height of the lateral humerus The height of the lower tibia from the ground is called the height of the external humerus. It is mainly used for the design of low waist shoes.

(11) The height of the heel of the heel is followed by the height of the heel from the ground. It is mainly used for the design of the back of the shoe last.

(12) The height of the boat's upper point is the height of the boat's upper point. It is mainly used for the design of the boots. (13) The height of the anterior tibia is the height of the anterior humerus. It is the main size that determines the level of the shoe's face.

(14) The height of the first metatarsophalangeal joint is the height of the highest point of the first metatarsophalangeal joint from the ground and is the main size determining the thickness of the toe joint of the shoe.

(15) The height of the big toe is the height of the front end of the big toe from the ground, which is the main size that determines the thickness of the shoe head.
