What is flat foot?
Flat foot, in simple terms, means that the arch of the foot collapses and the sole of the foot is almost completely on the ground. This situation not only affects the shock absorption ability of the foot, but may also cause a series of problems with the knee joint, spine, and even body posture. Although mild flat feet may not cause obvious discomfort, long-term neglect will often cause the problem to “extend from the sole of the foot to the whole body.”
How does the plantar pressure analysis system identify flat feet?
Compared with the traditional observation method or ink method, the plantar pressure analysis system is a high-tech, data-based detection method that accurately restores your “real landing state” by measuring the pressure on each area of the sole of the foot.
Principle 1: Pressure sensor array captures plantar pressure distribution
When you stand on a pressure plate or wear a pressure pad, the high-density sensor array in the system will collect force data from various areas of the sole of the foot in real time. Whether the pressure on the heel, forefoot, and middle of the sole is uniform, the system can see at a glance.
Normal arch: The pressure in the middle of the sole is small or close to zero, and the midfoot is “suspended”.
Flat feet: The middle part of the sole will also show obvious pressure values, even close to the pressure of the forefoot and heel, indicating that the arch of the foot is collapsed and the midfoot is touching the ground.

Principle 2: Dynamic gait analysis to observe the functional performance of the arch of the foot
More advanced plantar pressure analysis systems can also perform dynamic tests – such as changes in foot pressure during walking and jogging. The system collects pressure images at different time points in the gait cycle to determine whether the arch of the foot plays a normal buffering and supporting role during exercise.
If it is found that the arch area is always under excessive pressure during exercise and lacks a “lifting” action, it may be functional flat feet, indicating that its arch support ability is weak and the risk is higher.
Principle 3: Center of gravity transfer trajectory analysis to identify gait abnormalities
The plantar pressure analysis system will also track the path of the center of gravity movement, from the heel landing to the toe leaving the ground, is it stable, is it biased to the inside or outside? People with flat feet are often accompanied by excessive pronation, that is, the center of gravity is seriously offset to the inside, which can easily lead to abnormal knee pressure and fatigue accumulation.
This method of analyzing from the dual dimensions of “mechanics + motion trajectory” is much more scientific than “looking at footprints”.
Technology scanning, guarding health
A few minutes of plantar pressure analysis report is not just a simple picture, but a “foundation physical examination” of your body structure. For ordinary people, it can help you choose the right shoes and prevent sports injuries; for athletes and people who stand for a long time, it is a precise assessment and early warning method.
