Clinical Design Objectives
Leg length discrepancy can contribute to altered gait mechanics, pelvic imbalance, lower limb asymmetry, and increased stress on musculoskeletal structures. This project was developed to provide controlled heel elevation while maintaining proper foot support, stability, and overall orthotic effectiveness.
Key Design Features
Integrated Heel Lift System
Anatomically incorporated heel elevation designed to assist in the management of structural and functional leg length discrepancies.
Achilles Tendon Stress Reduction
Heel elevation helps reduce tensile loading on the Achilles tendon while promoting improved lower limb comfort during daily activities.
Plantar Fascia Support
Optimized rearfoot positioning assists in reducing excessive strain on the plantar fascia and related soft tissue structures.
Deep Heel Cup Stability
Contoured heel cup geometry improves calcaneal control, enhances foot positioning, and minimizes heel slippage inside footwear.
Supportive Arch Foundation
Integrated arch support promotes improved load distribution and contributes to overall biomechanical alignment.
Patient-Specific Adaptability
Design parameters can be modified according to clinical prescriptions, patient anatomy, and biomechanical requirements.
CAD Development Process
The orthotic model was professionally developed in Rhino 3D using advanced orthopedic CAD methodologies. Smooth anatomical transitions, controlled heel elevation geometry, and manufacturing-ready surfaces were incorporated to ensure accuracy and production compatibility.
Manufacturing Compatibility
The final model utilizes watertight CAD geometry optimized for modern podiatry and orthotic manufacturing workflows, enabling efficient integration into digital production environments.

Customization Capabilities
The design can be further customized to accommodate varying heel lift heights, arch support requirements, foot morphology, pressure redistribution strategies, and practitioner-specific clinical prescriptions. This flexibility makes the model suitable for a wide range of orthopedic and rehabilitation applications.
Project Outcome
A production-ready orthopedic insole featuring an integrated heel lift system that combines biomechanical support, improved rearfoot stability, leg length discrepancy accommodation, and seamless compatibility with modern CAD/CAM manufacturing technologies.
The orthotic incorporates a 40° medial arch skive correction specifically designed to increase medial arch control and support improved foot alignment during gait. This biomechanical feature assists in stabilizing the rearfoot and controlling excessive pronation for enhanced functional support.
An integrated metatarsal pad with adjustable height ranging from 1–5 mm is included to provide targeted forefoot pressure relief and improved metatarsal support. This feature helps redistribute plantar loading and improve comfort for various clinical and accommodative applications.
The insole also features a lightweight hexagon perforation pattern with 1.5 mm openings optimized for airflow ventilation, structural weight reduction, and flexible 3D printing performance. The perforated geometry enhances material efficiency while maintaining overall structural stability for additive manufacturing workflows.
