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.

Had these boots for closer to 6 months now. I work in the field of commercial, industrial, maritime and offshore hvac and refrigeration. These boots take a beating and keep going. They did take some time to break in but not as bad as my ****** boots. Went with smooth uppers and roughout bottoms. These are a dream to wear. These have gotten soaked and dried out fairly quickly. Accidentally ordered the 6in but I’ve loved them. They did have some cosmetic issues but that didn’t faze me. I knew I’d be beating on them. Will be getting a second pair eventually.

These are by far (I own White's, Danner and two pairs of Thorogood) the best quality boots I've ever owned. Simply gorgeous leather and bullet proof construction. I could not be more pleased with my purchase. They're almost too handsome to get dirty.

Placed my order and received them in 3-weeks. Little break-in is correct. Wore them to work ,nine hrs on cement floors , the next day and every day since. Heavy boots at over 3-pounds each, I don’t even notice it when I have them on. They are like leather armor for my feet. The red X soles are hard,but they are chemical resistant. So if that wasn’t necessary I would get the honey soles. Well worth the money, wish I had bought them years ago. I wasted a lot of money on Thorogoods and the likes.

The boot is perfect for what I do, boat captain for environmental recovery, and landscape installer. We do a little bit of everything, from massive water features, heavy equipment operation to shovel work. These boots are as versatile as I am and the quality is beyond expectations. I would normally blow through a pair of danners in 4 months and in one month they would already show significant signs of wear. I have these for two weeks and they broke in with no hot spots or blisters. Follow the sizing instructions and you will love them like I do.

These have survived 3 weeks at the steel mill welding/fabricating heavy equipment 10-13hrs a day. Not one stitch frayed or popped. Tough boots for one of the harshest environments you can put boots in.
