Carbon fiber is a super-strong, super-light material that we associate with the finer things in life—supercars, luxury phones, designer accessories. However, Timberland puts the material to work with a tough new pair of six-inch Helcor boots that are equally at home off the beaten path or traversing the gritty urban jungle. They’re completely waterproof thanks to their seam-sealed construction, and feature anti-fatigue tech that’ll keep you on your feet all day, which isn’t something you can say for every pair of slick boots out there. Kick ‘em on with a pair of jeans, or pair them with a suit to show the boardroom who’s boss.
