A carbon fiber weave reaches that rating with less material, so the toe cap is lighter and slightly less bulky than a standard composite cap — which is why it shows up on boots meant for walking rather than heavy loggers.\u003c\/p\u003e\n\u003ch3\u003eCan I use my own orthotics?\u003c\/h3\u003e\n\u003cp\u003eYes. The AG8™ footbed lifts out. The CA5540 is EH rated rather than static-dissipative, so there's no SD rating to compromise by swapping it — unlike its ESD sibling, the CA5541.\u003c\/p\u003e\n\u003ch3\u003eHow long does the waterproofing last?\u003c\/h3\u003e\n\u003cp\u003eThe SCUBALINER™ is a sealed membrane rather than a surface coating, so it doesn't wash off. Conditioning the leather and keeping the seams clean is what keeps it working over the life of the boot.\u003c\/p\u003e\n\u003ch3\u003eIs it insulated?\u003c\/h3\u003e\n\u003cp\u003eThe CA5540 is uninsulated, which makes it a comfortable three-season boot. For cold work, the 8\" CA5547 carries 440g of insulation on the same carbon composite platform.\u003c\/p\u003e\n\u003ch3\u003eWhat safety standards does the Duke CA5540 meet?\u003c\/h3\u003e\n\u003cp\u003eThe carbon composite toe meets ASTM F2413 I\/C for impact and compression, the boot is EH rated (tested to 18,000 volts at 60Hz for one minute), and the rubber outsole is oil- and slip-resisting.\u003c\/p\u003e\n\u003ch3\u003eHow does the Duke fit?\u003c\/h3\u003e\n\u003cp\u003eIt runs true to size — order the size you wear in athletic shoes, and choose Wide if you normally need an EE width. The broad carbon composite toe leaves room across the forefoot, and the AG8 footbed is removable.\u003c\/p\u003e","brand":"Carolina","offers":[{"title":"7 \/ Medium \/
