Study on Ergonomic Footwear Design framework informed by lower limb Biomechanical Characteristics

Area of Science:

• Biomechanics
• Ergonomic Design
• Podiatric Medicine

Background:

• Foot ailments such as plantar fasciitis are rising due to poor footwear choices and urban environments.
• These factors disrupt natural foot biomechanics, highlighting the need for ergonomic solutions.

Purpose of the Study:

• To create an integrated ergonomic footwear design framework based on lower limb biomechanics.
• To translate biomechanical principles into practical design strategies for comfort, injury prevention, and mobility.

Main Methods:

• An interdisciplinary approach combining biomechanical literature, material science, and ergonomic design.
• Analysis of foot anatomy, gait mechanics, and footwear limitations to establish design principles.
• Focus on key components: toe box, rocker sole, arch support, and heel counter.

Main Results:

• A framework with specific design strategies: 10°-15° toe spring with lateral flexion grooves for joint motion.
• A 4-6 mm lateral heel wedge for postural alignment and rigid heel counters/torsion plates for stability.
• Adaptive closures for dynamic fit and enhanced gait support.

Conclusions:

• The framework effectively connects biomechanical theory with practical footwear design.
• Ergonomic footwear, prioritizing anatomical alignment and dynamic support, can reduce musculoskeletal stress.
• Future work includes 3D scanning and AI for personalized designs, positioning footwear as a health tool.
