300X - Brown
America's #1 everyday safety boot
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 300 boots is meticulously handcrafted in our Spokane, WA facility using only the highest-grade American leather, NFPA rated 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.

The 360° 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.

WHAT SHOULD I EXPECT
JK's handmade leather boots are unlike anything you have put on your feet before. Because we use the highest quality materials and construction, your boots will form to your feet over time, for the perfect fit.
Your boots may feel a little stiff or strange at first, and that is completely normal. The leather will settle to your feet: stretching, where there is tightness, and shrinking up where there is extra room. The insoles will form to your arches and toes, and the boots will soften and mold to your foot and calf.
Wear with a good pair of socks, trust the break in process, and enjoy a whole new level of footwear!
Brief history with JK Sizing
We are continuing to improve sizing experience for new customers based on current customer feedback to achieve the best results.
From our early days, JK Boots has been on a journey to improve our products, systems, customer experience, and methods. We never want to settle for good enough, we always want to get better!
As of March 2023, based on the market research, specialist consultation and customer feedback, we have updated our sizing method and chart, in order to increase the ease and simplicity in finding the best size for you.
This includes:
• Offering a larger variety of letter Widths
• Simplifying Boot Length determination Via the US Brannock device and Standard U.S Sizing
• Offering the Ball width Measurements chart
• Adding a printable Brannock Device & Tape Measure
• Adding a conversion Calculator
How Much Toe Room Should My Boots Have?
•Our "standard" toe room is based off of what we typically recommend–giving you about a thumb's width of space between your toe and the end of the boot. This leaves plenty of room for your foot as the leather settles, and shrinks back (curling the toes slightly) over time. With that in mind, everyone is different. You know your feet best, and should pick what sounds good to you, like if you know you have sensitive toes, go with a roomy fit, or if you prefer less material up front, than go with the snug fit.
How Wide Should My Boots Be?
Our boots are built to provide incredible support and comfort for extended periods of time, almost like a firm handshake. We have five widths to choose from (D (narrow), E (regular), EE (medium), 3E (wide), and 5E (Xtra-Wide), so simply select what sounds right.
