O.T. Pro 6。Durable leather boot with secure lace-up closure. Rugged rubber sole offers reliable traction. Padded ankle and reinforced stitching for long-lasting support and comfort. Stylish tan finish complements work and casual outfits. An American emblem, the Bison, thrives in the most extreme conditions. The famously soft hide moves with you across forests and plains, giving you increased agility and comfort wherever you roam. The O.T. boot is possibly our most versatile boot design to date. O.T. stands for “Over-Time” meaning this hybrid work boot is not just meant for the \"clock-in-and-out\" days, but for the long hours, varied conditions, and last-minute hiking trips. The dual sport design offers an exceptional balance of agility, comfort, and support, making them the perfect choice for city or mountain terrain. The O.T. is lighter and more flexible than our Superduty but still tough as nails. * Shaft Height - 8” (boot heels excluded) * Uppers - Smooth 8-9oz premium oil-tanned  shrunken USA bison leather * Lowers - Smooth 8-9oz premium oil-tanned  shrunken USA bison leather * Thread - Standard high strength cord * Hardware - Traditional brass high-quality eyelets and speed hook combo * Insole - Genuine oak-tanned USA leather * Midsole - Genuine oak-tanned USA leather * Arch support - USA leather * Sole - Vibram 132® Honey * Adhesive - Fire ready adhesives throughout boot construction * Lifespan - Rebuildable & Resolable * Origin - 100% Handmade in the Unit
