Core Data Measured by a 3D Foot Scanner
1. Key Basic Parameters of the Foot
A 3D foot scanner can measure essential dimensions such as foot length, foot width, forefoot width, heel width, arch height, and more — with an accuracy typically within 0.5mm.
Vertical parameters like arch height and instep height are especially useful for quantitatively evaluating risks of flatfoot or high-arched feet.
It can also assess arch support status based on plantar contact area distribution. For example, flatfoot is usually indicated by a significantly increased arch contact area.
Other parameters such as heel tilt angle and hallux valgus angle can aid in diagnosing issues like overpronation, supination, or bunions.
2. 3D Foot Shape and Biomechanical Features
The scanner generates a 1:1 high-precision 3D foot model, clearly showing arch curvature, plantar fascia structure, and surface features such as scars or wounds.
3. Applications in Foot Correction and Treatment
The data — including arch support point location, heel cup depth, and full 3D foot geometry — can be used to 3D print customized orthotic insoles.
It also provides correction angles for pronation or supination, which guide mechanical design in orthotic devices.
The scanner can also measure the Arch Index (arch height/foot length), which helps assess the severity of flatfoot.
4. Typical Application Scenarios
Medical Diagnosis: Quickly screens for structural abnormalities such as flatfoot, high arches, or pronation/supination.
Sports and Health: Supports the design of sports footwear tailored to arch type and athletic needs.
Rehabilitation and Therapy: Provides detailed data for designing orthotic insoles and braces, improving correction outcomes effectively.
