Core Components of Footwear Analysis
Footwear analysis relies on four essential testing categories that work together to evaluate a shoe's quality and performance. When you're examining footwear, you'll need to take into account material tests, physical properties, optical and thermal assessments, and forensic analysis components.
In material testing, you'll evaluate color consistency, UV resistance, and water degradation through hydrolysis tests. You'll also check for chemical migrations and blooming effects that could compromise the shoe's integrity. Laboratory conditions require conducting migration tests on PVC foil at 50°C to identify any color diffusion issues.
Physical property tests help you determine density, water content, and melt volume rates, which are vital for predicting durability and performance.
You'll want to conduct optical and thermal assessments to measure translucency, yellowing tendencies, and thermal conductivity. These tests reveal how your footwear will maintain its appearance and comfort over time. The grey scale and post-hydrolysis color tests guarantee consistent coloring under various conditions.
For forensic and performance analysis, you'll examine pattern evidence, wear characteristics, and both class and individual characteristics. These components help you identify specific shoes and evaluate their performance features, including flexibility, stack height, and cushioning properties.
Sensor Technology Behind Walking Tests
Through advanced sensor integration, walking test analysis has evolved into a sophisticated process that combines multiple sensor types to capture thorough gait data. You'll find accelerometers measuring movement acceleration, gyroscopes tracking angular velocity, and pressure sensors analyzing foot function working together in modern walking test systems.
The strategic placement of these sensors maximizes data collection effectiveness. You can expect to see sensors embedded in shoes, attached to key body points like knees and thighs, or integrated into floor-mounted platforms. Early detection of abnormal walking patterns helps prevent future injuries.
IMUs combine accelerometer and gyroscope capabilities to provide exhaustive movement analysis, while in-shoe sensors capture detailed pressure distribution patterns.
The collected data undergoes sophisticated analysis using machine learning algorithms and feature extraction techniques. You'll benefit from PCA methods that streamline large datasets into manageable insights, while segmentation approaches help break down complex gait patterns.
This technology enables real-time feedback through smart shoes and supports long-term gait monitoring. When combined with artificial intelligence, these sensor systems can identify subtle gait abnormalities and help design customized orthotics, making walking test analysis more precise and actionable than ever before.

Walking Parameters and Metrics
Real-time measurement systems capture a thorough set of walking parameters and metrics that define human gait. These parameters fall into three main categories: spatial, temporal, and spatiotemporal measurements. Each category provides unique insights into your walking patterns. Clinical analysis of these parameters helps experts evaluate pretreatment and rehabilitation progress.
Spatial parameters focus on the physical aspects of your steps. They include your stride length (distance between consecutive footprints of the same foot), gait height (measured between the stereo camera and opposite foot marker), and minimum foot clearance during swing phase. You'll also find measurements of your strike angle when your foot impacts the ground.
Temporal parameters track the timing of your movements. They measure your stride time, step time, and the duration of stance and swing phases. Your cadence, or strides per minute, falls into this category too.
