* All measurements are in inches unless otherwise noted. Measure over light clothing for apparel.
* Running shoes: measure your feet in the afternoon or after a run, wearing the socks you plan to run in.
* If you are between sizes, we recommend sizing up — especially for running shoes, because feet swell during activity.
* Men's standard shoe width is D; women's standard width is B. Wide options are usually 2E/4E for men and D/2E for women.
* Actual garment fit may vary slightly by style, fabric stretch, and brand.
