A last is the mold that gives your boots their shape and determines how they fit around your foot. Each Nicks last has a different combination of arch support, toe shape, and toe-box width, so choosing the right one helps you customize your boots for your feet and how you plan to wear them.

Mismates are a pair of boots made in two different sizes to accommodate feet that differ in length, width, or both. They can provide a more precise fit when one foot is noticeably different from the other. Not applicable for 99% of customers.
The outsole is the part of the boot that meets the ground, affecting traction, durability, and comfort. Different outsoles are designed for different terrains, work environments, and everyday wear.

A relief cut is a notch in the leather at the ankle that allows the boot to flex more naturally and reduces pressure or pinching during break-in. It’s a great option if you want increased flexibility and comfort, especially with stiff leathers.
Choose the toe structure that best suits your needs, from a flexible soft toe to reinforced Celastic or ASTM-rated protective toe options. Learn more about toe structures.

The cost is high but the quality and craftsmanship make them a great deal! My first pair of Nick's were a bit extra roomy and I was thinking about adding an insole. After talking with some people on the Reddit I was gifted a half Delta Arch. That was an incredible improvement in comfort and sizing but I Knew I still needed a full Delta! Wearing them now and couldn't be happier!
Exactly what I need to fill out the HNW insoles. I have very high arch’s and these are perfect
Amazing high quality products that keeps you on your feet
Little does my wife know I’m ordering 5 more pair. Got these because I was in search of a leather footbed that would allow my feet to breathe and be smell free in any shoe. Currently I have these in a pair of Lems, but have used them in New Balance skate shoes, and Adidas terrex hiking shoes. These take a break-in period. So good!!
I was very excited to receive these for my boots. Unfortunately, they only come in one width, which is D or Regular. I contacted customer service right away because my pinkie toe was falling off the edge in my 9E Nicks boots. I was told next time i should order a couple sizes up and trim them down because they only have one die in every size. Now i am not an expert on feet, but to me that sounds like it would put the arch of the insole in the wrong spot. If it were me i would get a EE size die for every size so the customer can trim them to fit. Other than the fact that i spent $100 for insoles that i can't use, they do seem to be of excellent quality.
Feel good, I like them
Great purchase! Fits great will do a 55 last next times
A bit squeaky at beginning, after oiling they’re great leather quality and I really like having and extra layer of leather under my feet.
The leather is good quality. Arch support is good right now, but will see how it holds up. Overpriced. 50 dollars seems more appropriate.
They formed to my feet within a few days and feel great. I can't tell you how much money I've wasted on foam over the years not knowing leather could feel like that
These were great, I had a pair of 1000 mile boots that were too large, so no I snugged it up and got the arch support I wanted.
Rock solid product but I did not consider their width. There was no option for EE width so it came in a "D" width. I still might be able to make it work for me
They work great for my high arch
Good quality and well made. They made my very average boots feel more comfortable and a bit more premium.
I am slowly breaking these in with my new boots -FlexWorkPro. A perfect addition
They make the boots even more comfortable
Barely have ANY additional arch at all. Extremely disappointed especially when the price is considered.
Fit great and help my feet with proper support
I love the Premium Delta Arch supports but I think they are a little too pricey for what they are. Also, I have a very high arch and would like to see some made with double the arch support. They are very comfortable, but I can tell that I need even more. Still nothing compares to a classic arch 55 boot last.
These are exactly what you need if you have a high arch. Don't even think twice. I move these from my wedge sole boots, into my chuck 70’s, and back. They are perfect.
Makes my other boots feel much better!
Very nice quality insole. Initial impressions on first wear are very good. I put them in a wedge sole boot and they definitely support my very high arch. I'm looking forward to a whole day working in them. I recommend these insoles to anyone with a high arch.
The 1/8” thickness took up enough space in the toe box that I developed some hot spots on top of big toe and side of pinky toe. This was in 12.5d HNW work boot pro which is wider than my most comfortable boot that is a 12.5c on a 55 last. I corrected the hot spots by wearing a better sock with less pronounced toe seam. Overall I like them although they don’t mimic a 55last exactly. When I buy them in the future I would consider the half length version unless it was being used in a boot that was wider than my measured width.
These were the perfect insole for me to add some extra arch support on my high arch feet while also taking up some extra volume on a pair of boots that were just a little too wide.
I love the feel of my White's Cutters. I bought a pair of Viberg 310's, and they have almost zero arch support, compared to the Cutter's. The Viberg's were un-wearable out of the box. These insoles have solved the problem.
Works great
stiff the first day but being leather they form to the foot perfectly and i love them.
