We've developed the Infinity FD series to be the most comfortable work boots you've ever owned. Wherever the site, whatever the job, Infinity FD are anti-fatigue boots that deliver all the modern boot amenities you're looking for and traditional Thorogood reliability that doesn't compromise comfort for performance. On the job, in the field, or on the trail, these boots will keep you moving forward, while the anti-friction insole means fewer hotspots and blisters. Our waterproof, slip-resistant boots also include a multi-traction outsole and aggressive tread.

What makes the Infinity FD series different is the combination of Flex-drive construction; the anti-fatigue, high-rebound midsole; and the multi-traction rubber outsole. The patent-pending Flex-drive has a 51% welt at the rear of the boot, creating a stable platform in the heel and flexibility in the forefoot. This innovation means that you'll enjoy more flexible, comfortable work boots that maintain their superior durability. The proprietary Infinity FD compound delivers excellent shock absorption and fatigue-fighting energy return. The combination of seemingly endless flexibility and the energy-returning outsole on these anti-fatigue boots has the effect of driving you forward while retaining energy and momentum. You'll experience extended hours of comfort without sacrificing performance or durability.
