* All measurements are in inches unless noted. Measure over light clothing for accuracy.
* For shoes, measure your foot at the end of the day — feet swell slightly during a run.
* If you are between sizes, we recommend sizing up for a more comfortable fit.
* Actual fit may vary slightly by style, material stretch, and compression level.
