The Zamberlan Difference

Insulated for extreme cold

PrimaLoft® insulation paired with GORE-TEX® Insulated Comfort membranes provides the utmost waterproof protection and breathability while granting temperature performance down to -20C (dependent on additional
factors, including sock materials and user tolerance). 

Double BOA closures for customized fit

A patented double implementation of the BOA® Fit System allows for precise, individual adjustments of the upper and instep for a personalized fit, without needing to take off gloves in the cold.

Ultra-tough SuperFabric® construction

The 11" tall uppers are made with synthetic SuperFabric® and wrapped in a full rubber rand, offering greater support and protection against rugged terrain, snow, and water.

Stiffer, more responsive support for extreme terrain

The Ull's stiffer lasting board and TPU frame/stabilizer transfer workload from the foot to the boot, allowing for greater precision and a wide range of technical uses. 

Wide fit for cold weather comfort

The Wide Last fit is designed to accommodate insulation, wider feet, and use of extra sock layers in extreme conditions.

Rugged, dependable traction for heavy loads

The deep, robust tread of our exclusive Vibram® StarTrek II outsole is easy to clean and offers strong grip for downhill braking under heavy loads.

Resoleable & built for the long haul

Made in Italy and resoleable with original Vibram® outsoles for a lifetime of use.

Great boot. Really warm. A lot of support

These boots are amazing. I own another pair of Zamberlan's for summer hunting. I have worn these new boots every day since I received them. I've hiked in (-13) degree weather for several hours and many times in 10-15 degrees. My feet stay very warm, at negative (-13) I did feel a little cold but nothing that would make me nervous. I will be wearing these for all my winter hikes and hunts.

I’ve searched high and low for boots that can keep my feet warm. I’ve tried Danners, Sorel’s, Packs, and insulated hiking boots. Nothing I’ve tried has worked while sitting in a blind with single digit temps. A couple reviews stated these boots along with two pairs of socks have performed miracles for other hunters. Design and craftsmanship are excellent. As some of the other reviewers have stated, measure your feet carefully, read the sizing directions carefully as well. I ordered one half size smaller than I normally wear and these boots are a perfect fit. We’ll see how they perform in single digit with weather this elk season! I’m hoping for the best.

I am really enjoying these boots so far. The BOA system makes entry and exit super fast compared to to all other foot wear I own. This is a major plus for taller boots. I wear them more often because of this. They are quite warm but not tested in minus 25 yet. I just had my Zamberlan leather lined hiking boots from 1998 resolved last month. The quality of this brand is exceptional and worth the money.

Incredible! Best fitting and most comfortable boot I have ever worn

Pricey yes, but there is no compromise for warm feet while having circulation issues and wanting to enjoy the outdoors in the winter. These boots come as advertised, the week of March 17 - 23 we had a really cold 🥶 snap. Minus 15 with just a pair of cotton socks on and my feet were the warmest they have ever been while outdoors in the cold. The quality and craftsmanship are unsurpassed by anything else I have bought for the cold weather, the 2 lace boa system is amazing in regards to how you can control the comfort level across the arch of the foot and how you can keep the upper lace a little bit less snug to allow a more natural and comfortable fit to walk naturally without any binding whatsoever on the shins. The guarantee of what is covered for the life of the boots is unmatched and it is a big plus that these boots can be resoled with the Zamberlan/ Vibram startrek 2 tread pattern which is very good on ice and slippery snow covered walk ways. Amazing product and I would recommend these boots to any and all because of the fact that they come as advertised as stated by Zamberlan Italy. Thank you again Rebeca and Zamberlan, looking forward to purchasing a pair of outdoor hiking shoes for the summer.

I had very high expectations for these boots due to their cost. I was not disappointed. I’ve worn these boots on a late season archery deer hunt and hikes where I live. Temps ranged from single digits to upper 20’’s. I am an older guy and have poor circulation and always struggle to keep my feet and hands warm in those temps. I also need a boot I can hike in with good support, my Salmon River packs(similar to the Kenetrek packs) have been my cold weather hunting boot, but no more. These boots kept my feet warm, much warmer than my packs, even with extended stationary glassing sessions and if I felt a little chill in my feet a short walk warms them up and I’m good to go. I’ve tried these boots with a variety of sock combinations, from a single KUIU merino wool hiker sock, to 2 pair of them, to a 3 sock combo liner sock, mid-weight KUIU sock, and the hiker sock. These boots easily accommodate these sock layers and never felt too tight. The dual BOA lacing system is awesome and makes it easy to adjust the tension. The sole on these boots is firm without being too stiff, but holds well when side hilling. It is also shaped so that your foot rolls over when you walk, making walking easier! My only complaint is that when walking in snow this action makes the boots kinda slip, but it’s not a big deal and overall the traction on these boots is very good. These boots have been super comfortable from the moment I put them on my feet went “Ahhhh”! The only thing I haven’t tested fully is their durability, but I’m confident they will hold up for many seasons, they are well made boots. I highly recommend these boots, they are my new go to boots for all my late season or winter hunts, hikes, or outside work.

So far, these boots are everything that I hoped they would be. They are the most expensive boots that I have ever owned, but worth every dime. They are the easiest boots to get on and off ever. They are warm, comfortable out of the box, and light weight for an insulated boot. PERFECT!
