SIZE GUIDE
Sized to your boot, because that's the number you actually know.
| Size | US Men's boot | US Women's boot |
|---|---|---|
| M | 6–9 | 7½–10½ |
| L | 9½–13 | 11+ |
Between sizes? Size up — a work sock should never pull at the toe cap.
Crew height on all pairs: tall enough to clear any boot collar, no calf squeeze.
