Superduty Bison - Shadow (Roughout/Smooth)

The unique combination of the bison's strength and flexibility is prominent in our entire Bison collection. The moment you slip on a pair of these one-of-a-kind work boots they mold to your feet because of how soft and thick the hides are. Expect no break-in, instant comfort, and long-lasting support wherever you roam. Like its namesake, the Superduty Bison is a born survivor: known to walk straight into the head of a storm, unfazed by uncertainty. The ultimate irony of the bison leather is that it blends a near-impossible combination of softness and strength. Whether you need them for 8 hrs or 24 hrs, the Superduty Bison will show up again and again to offer support that keeps you moving without straining your feet or calf muscles.  Specifications Shaft Height - 10" (boot heels excluded) Uppers - Smooth 8oz premium oil-tanned USA leather Lowers - Roughout 8oz premium oil-tanned USA leather Thread - High strength, NFPA compliant Technora® fire resistant to over 900 °F Hardware - Traditional brass high-quality eyelets and speed hook combo Insole - Genuine oak-tanned leather Midsole - Genuine oak-tanned USA leather Arch support - USA leather Sole - NFPA compliant Vibram RedX Fire Hard  Adhesive - NFPA compliant adhesives throughout boot construction Origin - Handmade in the United States of America
