How to Read Unisex Shoe Size Labels

Find the base scale

A unisex shoe may list men’s and women’s US labels together, or emphasize only one of them. Nike’s men’s-based unisex chart publishes both rows. Read the heading rather than assuming the first number is the system you usually buy. A single number without a country or category is incomplete information.

Use a published conversion, not a universal offset

Nike’s chart uses a 1.5-size difference between the men’s and women’s US labels for its shared unisex product. That is a manufacturer example, not a rule for every brand. Use the chart attached to the product; an offset tells you about labels, not heel shape or upper volume.

Same label length does not mean the same construction

Unisex footwear can share one last across the product range, while separately marketed versions of a shoe may use different widths or designs. Neither a colorway nor the US conversion proves construction is identical. Check the product description and the actual width selection.

Check availability at the edges of the range

A chart may show a broad conversion range even when a particular color or width is not offered in every size. Start with the correct size, then check stock in that category. If a suitable width is unavailable, changing the length number is not necessarily a workable substitute.

Before you order

1. Identify whether the displayed US size is men’s, women’s or dual-labeled.
2. Read the manufacturer’s paired label rows.
3. Check width and model-specific advice.
4. Measure both feet if changing brands.
