Why do shoe sizes vary by brand?
EU, US and UK labels use different numerical scales, and US sizing also differs between men's and women's ranges. Brands apply their own lasts, width assumptions and fit decisions, so the same foot length can appear as one label in one brand and a half size higher or lower in another.
The tables provide a practical closest match rather than a fit guarantee. For a new brand, use the product's official size guide as the final reference, particularly where the listing also specifies a narrow, regular or wide fit.
How to measure your foot length
Stand with your heel against a wall on a sheet of paper, keeping your weight on the foot. Mark the furthest toe, then measure from the wall edge to that mark in centimeters. Measure both feet and use the longer measurement when the two differ.
Foot length in centimeters is the most useful common reference when moving between sizing systems. Leave some space for socks and normal toe movement; the right allowance varies by shoe type and by the fit guidance from the brand.
Using EU, US and UK shoe size charts
Start by selecting the correct group, then choose the brand only when you know it. Enter an EU, US or UK label, or use your measured foot length. The displayed row gives the closest equivalent across the four systems and the table below lets you check neighbouring sizes.
Children's numbering has its own ranges: US sizes reset after 13.5 before youth sizes start again at 1. That is why toddler/little-kid and big-kid charts are kept separate from adult charts here.
