The complex 3D shape of an insole can be effectively represented by its overall size and two specific shape descriptors, which correlate with traditional arch measurements. This human factors research insight is drawn from a 2015 study published in PLoS ONE. Using Geometric morphometrics (gmm) with 158 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Focus on two key shape parameters derived from geometric morphometrics, which are linked to established arch measurements, for efficient insole design.
Insole Shape Can Be Simplified to Two Key Metrics, Mirroring Classic Foot Measurements

Key Findings
- 01Insole shape can be characterized by size and two principal shape components (relative warps).
- 02These shape components closely align with classic footprint measurements like the Chippaux-Šmiřák arch index and the Clarke arch angle.
Application
Design takeaway
Focus on two key shape parameters derived from geometric morphometrics, which are linked to established arch measurements, for efficient insole design.
How to apply
When designing insoles, consider using simplified measurements that capture arch height and forefoot/arch proportions, as these have been shown to be significant shape determinants.
Project actions
- 01When analyzing foot shapes for a design project, consider using established anthropometric measurements as a starting point.
- 02Explore how modern digital tools can complement or simplify traditional measurement techniques.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes advanced geometric morphometrics for detailed shape analysis.
- +Connects modern analytical techniques with established anthropometric measures.
Limitations
The sample was limited to adult females, and the study focused on a specific cross-section of the foot, not the entire 3D geometry.
Reliability & validity
The use of geometric morphometrics and a defined sample size contributes to the reliability of the shape analysis. Validity is supported by the alignment of findings with established anthropometric indicators.
Think critically
To what extent can simplified anthropometric measurements fully capture the nuanced requirements for ergonomic footwear design, especially considering variations across different populations and activities?
Design Principles
"Complex forms can often be reduced to a few salient features for practical design and analysis."
Understanding these core shape components allows for more efficient design and manufacturing of insoles. It suggests that simplified measurement techniques can capture essential design variations, potentially reducing complexity in product development and customization.
What This Means for Your Design
The study shows that you can understand the shape of an insole by looking at just two main features, which are related to old ways of measuring foot arches.
