Americans needed an effortless everyday boot, so we built the 300X model, in honor of the 300+ million hardworking individuals that build up our nation. Made by hand with quality materials to feel incredible from the moment you slip them on, till the moment you almost forget to take them off. So comfortable right out of the box, that you will want to wear them everywhere. Each set of 300X boots is meticulously handcrafted in our Spokane, WA facility using only the highest-grade American leather, fire ready materials, Vibram RedX Fire soles, and stitchdown construction. This attention to detail means your JK work boots are built to keep you comfortable and safe providing real comfort on and off-site. Hours of standing, hauling, and getting the job done are met with a wear-resistant sole, supple leather, and lightweight flexibility. The 360Adeg stitchdown construction affords a watertight seal and EH readiness with the complete elimination of nails and screws. Like the hammer in your toolbox, the 300X boot is versatile, tough, and comfortable to handle.
