Fit and sizing explained
Fit Problems Explained
Most fit issues come down to measurement, not the size itself. Measuring your foot length in centimeters and comparing it against the chart removes most of the guesswork.

Why Sizes Vary
Shoe sizing systems were built independently by region, so a size label alone can’t be compared directly across countries. Anchoring to a physical measurement is the reliable way to translate between them.
Brand Differences
Brands use different lasts and fit models. Nike often runs small; Adidas and Puma can differ by style. Always check the brand's size chart before ordering.
Regional Differences
Regional shoe sizing systems evolved independently, so the same foot length gets a different number in the US, UK, EU, and Japan. Comparing foot length in centimeters is the most reliable way to check a size across regions.

User fit warnings
Always check the brand's official size chart for the specific product. Sizing can change by season and style. When between sizes, consider sizing up for comfort or ordering two sizes and returning one. Read recent customer reviews for fit notes.
