Multi-Brand Shoe Size Converter & Comparison

Converting from Adidas to Nike is usually straightforward. Since Adidas tends to run slightly large, you'll typically wear the same size in Nike. Our cross-brand converter gives you the exact conversion, so you can shop with confidence knowing you're getting the right fit. The comparison tool also shows you detailed size patterns between these brands.

Nike to New Balance is one of the easiest conversions! Both brands generally run true to size, so your Nike size will likely be the same in New Balance. The bonus? New Balance offers more width options if you have wider or narrower feet. Our converter shows you the exact size match, and the comparison chart highlights New Balance's width advantages.

Puma has its own sizing quirks - they tend to run slightly small compared to Nike and Adidas. When converting from Puma to other brands, you might need to go up half a size. Our cross-brand converter takes the guesswork out of this for you, and the brand comparison tool shows you exactly how Puma sizes compare to other major brands.

The main difference is that Nike runs true to size while Adidas runs slightly large. Nike uses standard US sizing, while Adidas has unique EU sizing with fractional sizes (like 42 2/3). Our cross-brand converter handles all these differences automatically, and the comparison chart shows you the exact size differences between these popular brands.
