How AI SizeCheck Works

Four simple steps to perfect-fit Adidas shoes, every single time

1

Capture Your Feet

Use your smartphone camera to take photos of both feet from multiple angles. Our AI needs just 3 images per foot.

Stand on a piece of white paper for best results. The AI analyzes your foot shape, arch height, and toe spread in real-time.

2

AI Analysis

Advanced machine learning algorithms process your images to create a detailed 3D foot model.

Our neural network measures 27 key dimensions including length, width, instep height, heel width, and toe box requirements.

3

Model Matching

The AI compares your foot profile against our database of 500+ Adidas models with detailed fit characteristics.

We account for material stretch, last shape variations, and construction differences across all Adidas categories.
