Warm, Dry, and Protected
Thinsulate™ insulation with an X-Static odor-resistant mesh lining keeps feet warm and fresh, the sealed SCUBALINER™ membrane keeps water out, and a carbon composite toe protects with reduced cold transfer.
Choosing an Insulation Weight
440 grams of insulation suits cold-weather work where you're moving — your own activity supplies part of the heat. For milder conditions, an uninsulated boot breathes better; for standing still in deep cold, look to 600g and above.
All-Day Comfort
A removable AG8™ Intelli/Sphere dual-density footbed cushions each step through long, cold shifts.

Frequently Asked Questions
What widths does the Duke 8" insulated come in?
Carolina offers this style in medium (D) and extra-wide (2E) widths, in men's sizes 8–14.
How cold can I wear this boot?
Its Thinsulate™ insulation is a winter-grade weight suited to cold-weather work — warm enough for freezing conditions during active work. The X-Static lining also resists odor buildup, which matters in an insulated boot worn all day.
Does the carbon composite toe transfer cold?
Carolina lists the carbon composite toe as non-metallic with reduced cold transfer into the toe box, while meeting ASTM F2413 I/C for impact and compression.
How does cement construction affect the boot?
The outsole is bonded directly to the upper rather than stitched through a welt, which keeps an insulated boot light and lets it flex from the first day, with no break-in underfoot.
Is the Duke electrical hazard rated?
Yes. It's electrical hazard rated, tested to withstand up to 18,000 volts at 60Hz for one minute without leakage.
What safety toe does the Duke have?
A carbon composite safety toe, non-metallic and meeting ASTM F2413 I/C for impact and compression.
