The application of plantar 3D scanners in custom sandals and high heels

1. Precise Foot Shape Data Collection

• Sandal Customization: Using non-contact laser scanning (precision ≤0.5mm) to obtain key parameters such as arch height and toe spacing, optimizing cut-out designs and strap fit to avoid rubbing or pressure issues.

• High Heel Adaptation: Combining 3D modeling to analyze forefoot pressure distribution (e.g., adjusting toe width when bunion angle >15°), ensuring heel height matches foot curvature and reduces metatarsal pressure.
  

2. Personalized Design Process

• Data Export & Modeling: Scan results directly generate STL files for 3D-printed lasts or carved molds, enabling rapid prototyping for complex designs (e.g., strappy high-heeled sandals).

• Dynamic Pressure Verification: Jointly testing forefoot pressure during walking with plantar pressure systems to optimize insole support zones (e.g., reinforcing mid-arch support in high heels).

3. Case Studies & Technical Advantages

• Case: A tech company achieved 40% better fit through scan data for personalized sandal cutting.

• Advantages: 10-second scanning, cloud storage for long-term foot tracking, ideal for seasonal adjustments (e.g., summer sandals).

4. Industry Trends

• Smart Footwear: Integrating gait analysis data for dynamic balance structures (e.g., adjustable heels).

• Material Optimization: Scan data guides localized use of breathable mesh or elastic materials to enhance summer sandal comfort.
