Carhartt Force HD 6 Inch Insulated Composite Toe Waterproof Boot

Carhartt Force HD Insulated Composite Toe Waterproof Boot

The Carhartt Force HD FX6393 insulated composite toe waterproof work boot is the pick when you want the Force HD platform for winter jobsites. It adds insulation to a waterproof, slip-resistant composite-toe boot, so cold, wet, and impact hazards are all covered in one boot. If you already run the non-insulated Force HD in warmer months, this is its cold-weather sibling to rotate in. It is a true insulated composite toe boot.

The Carhartt Force HD (model FX6393) is a $189.99 insulated, waterproof work boot with an ASTM F2413 composite safety toe and a slip-resistant outsole. It is the winter counterpart to the non-insulated Carhartt Force HD FX6305, and it competes with insulated composite boots like the KEEN Davenport.

Why Buy the Insulated Carhartt Force HD

• Insulation for cold jobsites — the single reason to order this over the non-insulated FX6305; keeps feet warm through winter shifts outdoors.
• ASTM F2413 composite safety toe — I/75 C/75 protection that is non-metallic, detector-safe, and won't pull cold into the toe box the way steel can.
• Waterproof construction — keeps snow-melt, slush, and rain out; maintain the seal with boot care and waterproofing.
• Slip-resistant outsole — grip on wet and icy-adjacent surfaces, so it also lives in our slip-resistant footwear lineup.
• Carhartt Force HD durability — the rugged Force HD build shoppers already trust, now specced for winter.

Carhartt Force HD Insulated Specifications

Jobs and Hazards This Boot Fits

Order the insulated Force HD for winter construction, outdoor utility work, cold-storage floors, and any job where feet get cold and wet at the same time. Insulation plus waterproofing plus a composite toe means one boot handles the whole cold-weather hazard stack. If your work is warm-season, buy the non-insulated Force HD FX6305 instead, which also carries an EH rating. Pair either with warm work socks and a supportive insole from our work boot insoles range.

Fit, Sizing, and Who Should Size Up

The Force HD runs true to Carhartt sizing in a medium width. Because this is the insulated version, the interior sits a touch snugger — if you plan to wear thick winter work socks, size up a half size so circulation stays good and your feet stay warm. Cold feet are often a fit problem, not just an insulation problem. For measuring and width guidance, see how to choose safety boots. Available in sizes 8 through 13.

Carhartt Force HD Insulated vs Non-Insulated

Choose the insulated FX6393 for winter; choose the non-insulated Force HD FX6305 for warmer seasons and its EH rating. Both waterproof boots sit in our waterproof work boots collection, and the FX6305's EH build is featured in our best electrical hazard work boots guide.

Carhartt Force HD Insulated FAQ

The FX6393 is insulated for winter; the FX6305 is non-insulated and carries an EH rating. Rotate them by season.

Composite, rated ASTM F2413 I/75 C/75, so it is detector-safe and won't conduct cold into the toe.

Is this Force HD waterproof?

How cold can I wear this boot?

The insulation targets winter jobsites; pair it with warm socks and size up a half for the coldest days. See our winter boot guide.
