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. Born in the heart of the northwest, sourced and handmade entirely in America, these all-purpose boots keep you moving anywhere, anytime. Each set of O.T. boots is meticulously handcrafted in our Spokane, WA facility using only the highest-grade American leather, fire ready materials, Vibram 132 Honey soles, and stitchdown construction. This attention to detail means your JK work boots are built to keep you comfortable and safe around the clock no matter what the situation. We are not intimidated when the road ends. We will build our own.
