Shoes

Which shoe brands run small or large?

Every shoe brand publishes a size chart, and many say which foot length each size is built for. Put 15 of those charts side by side and the brands that run small or large show up in the brands' own numbers.

Each brand's US women's 6 to 10 against the median of the other charts. Shortest-running charts first.

Gap: how much longer (+) or shorter (−) a foot each size is built for, against the median brand. Tinted rows are half a size or more away.

How to read this

A chart that runs long builds each size for a longer foot than most, so on length alone you need a smaller size, and the other way round. It is a comparison of charts, the brands' own claims, so it measures length only. Width and toe shape are on no chart and can make a shoe feel smaller than its chart says.

To go from a size you already wear at one brand to another, use the shoe size converter.

Brands whose chart has no foot lengths

Their charts only convert labels (US to UK to EU), so a chart cannot say whether they run small. Their pages still show what size to buy from the brands you know.
