1. Introduction

For decades, shoppers have struggled with inconsistent shoe sizing across brands and regions. Wrong size purchases not only frustrate customers but also lead to costly returns for retailers.

Perfitt created PerfittSize, an AI-powered fit solution that helps global footwear brands and retailers boost conversions, cut returns, and deliver a better shopping experience.


2. The Global Sizing Problem

  • Online footwear sales continue to grow rapidly, but size uncertainty remains the #1 barrier.

  • Shoppers often “bracket” purchases (buying multiple sizes and returning the rest).

  • Retailers lose margin to logistics, return handling, and customer churn.

The result? Lower trust, lower loyalty, and significant operational inefficiencies.


3. PerfittSize Technology

🔹 AI Size Indicator

Perfitt’s proprietary AI Size Indicator leverages a unique inner-shoe database across 400+ brands and 60,000+ models.

  • Shows whether a shoe runs small, large, or true-to-size.

  • Reduces hesitation before checkout.

  • Requires zero manual effort from retailers — data is auto-generated from Perfitt’s system.
