Summary
Computer-aided design (CAD) systems show promise for custom orthopedic footwear. A clinical trial of the Shoemaster system demonstrated its capability to handle unique last shapes and integrate into a complete design workflow.
Area of Science:
- Orthopedic biomechanics
- Computer-aided design (CAD)
- Footwear engineering
Background:
- Computer-aided design (CAD) is standard in mass-produced footwear.
- Orthopedic footwear presents unique design challenges due to patient-specific requirements.
- The application of CAD in orthopedic footwear design requires careful evaluation.
Purpose of the Study:
- To assess the technical capabilities of the Shoemaster CAD system for orthopedic footwear.
- To evaluate the system's potential for improving service and cosmetic appearance in custom footwear.
- To investigate the system's adaptability to non-standard last shapes and its integration potential.
Main Methods:
- A clinical trial was conducted using the Shoemaster (Clarks Shoes) upper design system.
- The system was evaluated for its ability to process unusual last shapes dictated by medical needs.
- The potential for integrating the system into a comprehensive CAD workflow for lasts and uppers was assessed.
Main Results:
- The Shoemaster system demonstrated proficiency in handling non-standard last shapes.
- The system shows promise for integration into a complete computer-aided design workflow for orthopedic footwear.
- Technical evaluation indicated positive capabilities for custom shoe design.
Conclusions:
- The Shoemaster CAD system is a promising tool for the orthopedic footwear industry.
- The system's ability to manage unique shapes and integrate into design workflows is advantageous.
- Further development could enhance its role in producing bespoke orthopedic footwear.
