The O.T. is our most versatile boot design - and now it comes in a shorter 6" profile built for everyday wear. Still true to its name "Over-Time," this boot works as hard as you do: long hours, rough conditions, and those last-minute calls to hit the trail. Crafted from rugged Pioneer Bison leather, every pair is one-of-a-kind with bold grain and a supple hand that breaks in fast but holds strong mile after mile. Lighter and more casual in height, yet still anchored by our flexible stitchdown construction and a classic black sole, this boot balances toughness with all-day comfort. Born in the Northwest, sourced and handmade in America, the 6" Bison O.T. is built to move between city streets, job sites, and mountain trails without missing a step. Because when the season calls, these are the boots you&';ll reach for - and the ones that won&';t let you down.
