Women’s shoes are also often narrower, so if you are between sizes in a men’s shoe, the half size down may fit better in length but not in width.
How the shoe size converter works
ShoeSizeChart converts through foot length. US men’s sizes follow the Brannock scale: size = 3 × foot length in inches − 22, so each size is a third of an inch. US women’s sizes are 1.5 higher for the same foot, and UK sizes one lower than US men’s. European sizes are counted in Paris points of two thirds of a centimetre and include about 1.5 cm of toe room: EU = 1.5 × (foot length in cm + 1.5). Mondopoint, used in Japan and for ski boots, is the foot length itself. Results are rounded to the nearest half size.

Brands use their own lasts and charts, so sizes can differ by half to a full size, and width (narrow, regular, wide) is separate from length. Try shoes on or check the brand’s chart and return policy. Children’s sizes are not covered.
