While both 2D and 3D scanning techniques are popular for making custom foot orthoses, they differ significantly.
2D imaging gives a detailed view of the sole of your foot, while 3D scanning captures your entire plantar morphology, helping detect anomalies more effectively. This makes 3D scanning essential for producing foot orthoses suited to your unique shape.
Both methods are diagnostic tools used by a podiatrist with distinct applications to relieve foot pain and pressure.
2D Foot Scanning
2D foot scanning uses a sensor-equipped podograph carpet to measure:
- Exact foot size;
- Type of plantar arch (flat foot, cavus foot, or midfoot);
- Weight distribution over the plantar surface;
- Foot positioning on a flat surface.
Advantages of 2D scanning include:
- Detection of plantar irregularities and their progression;
- Identification of postural imbalances;
- Quick and simple analysis;
- Better understanding of foot pressure responses.
Taking 3D Impressions of the Sole of the Foot
3D scanning provides a full, precise visualization of plantar morphology, surpassing 2D capabilities.
A 3D scanner captures the entire foot in detail, enabling the custom creation of insoles.
Benefits of 3D scanning include:
- Real-time visualization by your podiatrist;
- Individual analysis of each foot;
- Lower margin of error;
- Extremely precise foot modeling.
Your podiatrist may complement this with additional diagnostics like postural assessment and biomechanical exams to tailor orthoses to your movements and lifestyle.
Which Method Is the Most Efficient?
3D scanning is generally considered more efficient due to its comprehensive foot modeling and accurate data, making it indispensable in podiatry clinics.
Nevertheless, the effectiveness of the 2D scanner remains valuable for identifying foot sole specificities despite its limitations.
The podiatrist determines which scanning method best suits your needs to develop custom foot orthoses.
Footprint scanning typically helps treat conditions such as:
- Morton’s Neuroma;
- Hammertoes;
- Plantar fasciitis;
- Flat foot or cavus foot;
- Metatarsalgia;
