* Foot length in inches, per official Brooks Running size charts (brooksrunning.com).
* Leave about a thumb-width of space between your longest toe and the toe box.
* Brooks recommends ordering running shoes 1/2 to 1 size larger than your dress shoes.
* Women's-to-men's conversion: subtract 1.5 from the women's size (e.g., women's 8.5 = men's 7). Unisex shoes run in men's sizing.
* Brooks offers Classic Fit (roomier, universal) and StealthFit (closer, more sock-like) — check the individual shoe's fit tag.
* Measure your feet at the end of the day, when feet are slightly larger; wear the socks you'll run in.
