Patience. It is the fundamental quality of a successful pursuit. It means commitment, resilience, and composure. It means the difference between empty-handed and a wall-hanger. The Infinity FD is the boot equivalent of the patience of the pursuit. We’ve patiently and diligently researched, designed, and built a technical, pursuit-driven boot with uncompromising comfort and performance. Thorogood’s patent pending Flex-drive 51% welt construction allows for maximum flex in the toe and enhanced heel stability. An anti-fatigue energy return system absorbs shock while propelling you forward. This combination of technologies delivers a relentless level of comfort and performance. With zero break-in and weather-defiant protection from the elements, the Infinity FD gives you infinite peace of mind, comfort, and confidence for limitless pursuits.
