Unlocking the Mystery of Shoe Sizing: How Perfitt’s is Transforming the Industry

The Size Challenge in Footwear

Despite advances in size and fit research, countless consumers still face frustration when choosing the right shoe size. Many researchers focus on measuring internal shoe dimensions and comparing them to foot measurements, hoping to offer precise recommendations. They even incorporate consumer reviews and return data to refine their methods. But if this approach is so effective, why does the struggle persist? Could inconsistent manufacturing, inaccurate data, or overlooked factors be the cause?

Perfitt’s Innovative Approach to Size & Fit Research

Perfitt took a closer look at these challenges by conducting a groundbreaking study. The team analyzed detailed internal shoe measurements and compared them to actual size choices made by customers. This research introduced the concept of "Size Sensitivity", highlighting how size selection varies across brands.

The study utilized a unique bar graph representation:

• Y-axis: Brands included in the research

• X-axis: Sensitivity score, which indicates the degree of variation in size selection.

A score of 0 suggested minimal impact from spatial variations, while longer bars reflected greater inconsistency in consumer size choices.

Insights from Perfitt’s Study

The analysis revealed that internal shoe dimensions are just one piece of the puzzle. Other critical factors—like the intended use of the shoe, its design, materials, and category—significantly influence size decisions. For example, brands with higher sensitivity scores often featured:

• Rigid uppers

• Performance-driven designs

• Durable outdoor-focused construction

These findings show the limitations of relying solely on internal shoe and foot measurements for size recommendations.

What’s Next for Shoe Size Research?

Perfitt is dedicated to pushing the boundaries of footwear sizing by integrating additional data points and enhancing prediction models. By addressing the complexities of design, material, and use cases, Perfitt aims to create solutions that minimize size-related challenges for consumers worldwide.
