If your work keeps you moving, the 400g CA3535 is the better match, since insulation ratings assume your own movement supplies part of the heat.\u003c\/p\u003e\n\u003ch3\u003eDoes the composite toe actually help in cold?\u003c\/h3\u003e\n\u003cp\u003eYes, and this is where it matters most. Steel conducts heat away from your toes, so a steel-toe insulated boot goes cold at the cap first regardless of how much insulation sits behind it. Composite doesn't.\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\u003eWhat safety standards does the Circuit Hi CA3538 meet?\u003c\/h3\u003e\n\u003cp\u003eThe composite toe meets ASTM F2413 I\/75 C\/75 for impact and compression, the boot is EH rated for electrical hazard protection, and the rubber outsole is oil- and slip-resisting.\u003c\/p\u003e\n\u003ch3\u003eHow does the Circuit Hi 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. With 800g of insulation the boot runs warm, so try it on in the socks you plan to work in; the EVA footbed is removable.\u003c\/p\u003e\n\u003ch3\u003eHow do I care for the Circuit Hi?\u003c\/h3\u003e\n\u003cp\u003eKnock off dirt, wipe the leather clean, let the boot dry away from direct heat, and condition the leather every few months.
