M4 does not mean one identical cut. Bootcut widens toward the hem; straight leg stays more even below the knee. Workwear versions can also differ in rise and construction.

Choosing your size
Measure your waist, fullest hip and inside leg. In a size such as 32 × 34, the first number is waist and the second is inseam, in inches. Try the length with the boots or shoes you plan to wear.
Regular, Rebar and FR are separate shopping groups. FR means flame-resistant; Rebar alone does not indicate an FR rating. Check the selected garment’s stated rating for your workplace requirements.
