The standard (medium) width for women is B, while the standard width for men is D. Shoe boxes and labels will only identify widths other than standard. Within the shoes, wide and narrow widths are identified on the label, underneath the tongue — ie. T005N(2E).
When is additional width needed?
Visible stretching or bulging on the outsides of forefoot materials is a good indicator that additional width may be needed. These sizes are available in many of our Running and Training shoes. In some cases, men can wear women’s styles to achieve a narrow fit and women can wear men’s to get a wide. If this is needed, please use the references above to determine comparable size lengths. Please note that the differences of width between narrow, standard, wide, and extra wide are usually only a couple millimeters and are proportional to the size of the shoe. Most additional width will be found in the forefoot.
