Unisex Sizing Guide
Confluence Running Sizing Guide
“Unisex” still needs a base sizing system.
Many unisex running products borrow an existing men's size scale; others use a brand-specific conversion or shared alpha sizing. Identify the base before you convert.
Unisex running shoes
Many performance shoes and spikes use men's sizing as the reference, but that is not universal. Always use the manufacturer's stated conversion.
Unisex apparel
Alpha-sized unisex apparel can be cut differently from gender-specific garments. Compare chest, waist and hip measurements with the brand chart.
Width codes deserve extra attention
If a unisex shoe is based on men's sizing, a D is generally a regular men's width. That does not mean it is equivalent to a women's D, which is generally considered wide in women's footwear.
A shopper who normally wears a women's Wide (D) should not assume that a men's-base unisex D provides the same relative width. Use the brand's stated conversion and consider actual shoe shape, including heel, midfoot, forefoot and toe-box geometry.
Best practice for unisex sizing
Men's, women's or brand-specific.
Avoid universal rules when the brand provides its own.
Know whether the width code follows men's or women's conventions.
Use measurements and, for footwear, shape and volume—not only the printed size.
