Union-made in Carolina's Martinsburg, Pennsylvania factory, the Sarge Lo 309 is a no-nonsense 6" soft-toe work boot with three comfort technologies managing moisture, cushioning, and odor — on a resoleable welt.

Union-Made in the USA with Global Parts — Built by UFCW Local 1776 in Martinsburg, PA.
Comfort First
Heavily oiled leather that's supple from day one, a DRi-LEX® lining that pulls moisture off the foot, and a Poron® Permafresh insole that resists the microbes behind boot odor.
Built to Be Rebuilt
Welt construction stitches the dual-density PU outsole to the upper, so the 309 can be resoled rather than replaced.
Why Choose the 309?
A comfortable, American-made 6" soft-toe work boot with real moisture and odor management, for work that doesn't require a safety toe.

Frequently Asked Questions
Does the 309 have a safety toe?
No. Carolina builds it without safety toe components, so it carries no ASTM impact or compression rating. The steel-toe version is the 1309.
Are Carolina Sarge boots actually made in the USA?
Yes, with a qualification Carolina states plainly: assembled in Carolina's own Martinsburg, Pennsylvania factory by members of UFCW Local 1776, using globally sourced components.
Can the 309 be resoled?
Yes. Welt construction stitches the outsole to the upper, so a cobbler can replace the sole when the tread wears down.
What sizes and widths does the Sarge come in?
Carolina builds it in B (narrow), D, 2E, 3E, and 4E, with some widths running to size 18.
Is the 309 waterproof or insulated?
The 309 is an uninsulated boot without a waterproof membrane. The DRi-LEX® lining moves moisture outward, which keeps it comfortable across three seasons. For wet ground, Carolina builds boots with a sealed SCUBALINER™.
Does the EH rating still apply when the boots are wet?
Treat it as reduced. EH testing is performed under dry conditions; moisture, damp leather, and worn outsoles all degrade insulation. EH footwear is secondary protection — never a substitute for de-energizing a circuit or using primary PPE.
