Introduction
The foot is an important part of the contact between the human body and the ground. It is an important organ that absorbs shock when bearing weight and walking. Wearing ill-fitting shoes for a long time
Shoes may not only cause various foot diseases, but also easily cause sports injuries, thereby affecting the health of the whole body. Shoes and other products
The fit and comfort of the shoe depend on whether the shoe last conforms to the foot shape characteristics. The design should strictly follow the foot shape characteristics, and there should be a balance between the foot, the last and the shoe.
Perform data conversion. The foot model contains rich foot shape characteristics and can reflect the comprehensive characteristics of a specific group of people. For shoe lasts, insoles, and foot models,
The design of wearable devices and other related products plays an important role.
This document is developed based on the second national body size measurement data conducted from.2014 to.2018.This document is for Chinese adults
Based on the characteristics of three-dimensional foot size distribution and the application of foot size in the design of shoes, foot protection devices and other products, the adult
Human foot size classification settings and coordinate description of the three-dimensional foot model. The series of foot models established in this document can be used for shoe lasts, insoles,
The design, verification, display and molding of products such as foot protection devices make them suitable for the characteristics of Chinese feet and improve the comfort of wearing the products.
Adult 3D foot model
1 Scope
This document gives the foot size classification settings for adults (18 to 70 years old) and the coordinate description of the three-dimensional foot model.
This document is applicable to the specification design and selection of shoe lasts, insoles, foot protection devices and other products.

3 Terms and definitions
The terms and definitions defined in GB/T 5703-2023 and the following apply to this document.
3.1
foot length
The maximum distance from the back of the heel to the tip of the longest toe (the first or second toe).
Note. When measuring, make sure it is parallel to the longitudinal axis of the foot.
3.2
footwidth
The maximum distance between the inside and outside of the foot perpendicular to the longitudinal axis of the foot.
3.3
Foot circumference balgirth
The circumference starts from the tibial metatarsal point and passes through the instep, fibular metatarsal point and sole of the foot to the starting point.
3.4
acropodion
When standing, the point on the tip of the toe (the first toe or the second toe) that is farthest from the heel point.
3.5
From the highest point on the upper edge of the first metatarsophalangeal joint.
3.6
insteppoint
Take a vertical section at 50% of the foot length and the highest point where the section intersects the instep.
3.7
The most anterior point of the lower end of the tibia.
3.8
The most outwardly projecting point of the medial malleolus of the tibia.
