Adidas vs ASICS sizing: official chart comparison

Adidas US 9 → ASICS US 9. Technical reference; manufacturer labels may differ. Size labels and measured foot length are different quantities. A chart does not establish the fit of every model.

There is no verified brand-wide fit offset or reproducible wearer distribution in this dataset.

How to compare Adidas and ASICS sizes

Start with the men's US label on your current shoe, then use the comparison below as a chart reference. Confirm the model and market in each official guide before ordering.

This example uses the nearest published EU label in the ASICS chart. Matching chart references does not prove that the shoes feel the same.

Select the shoe chart scope in the converter. Women's results use a separately reviewed women's or documented unisex chart; missing scopes stay unavailable. These references do not establish a children's or width conversion.
