Reviews

Line Extreme

"I’ve had them for about 3 months now worn them every day since. Pretty quick break in time, Hands down the best boots I’ve ever worn, I think I’ve finally found my forever boot, Their great for everything I’ve thrown at them. Great for climbing and working all day in. Absolutely love them! Will buy another pair!"

The best work boots I have ever owned.

"I purchased these boots hoping for superior ankle support and stability compared to the more traditional safety toe boots I had been wearing for the past 20 years working for a Railroad. I was pleasantly surprised to find these are not only far more supportive and stable but they’re also by far the most comfortable after a week or two of break in. The foot bed and heel pocket were immediately comfortable, so no blisters or sore feet during break in to worry about. The toe box is roomy and the upper/foot area is roomy enough to allow for heavyweight wool socks during cold months, but has enough lace adjustment to cinch down snuggle over a mid weight merino wool boot sock. The boots are initially very stiff between the foot area and the ankle support area and took 7-8 days of wearing them to get more natural fore-aft flex over the ankle when walking. They’re now perfect and still nice and stiff side to side for ankle support. Additionally the full length heel to toe nylon shank makes walking on uneven railroad ballast rocks so much nicer. You don’t feel the rocks pushing into the footbed at all which is a huge win. Great boots, highly recommended."

Great Boots for Life

"Kenetrek Boots never ceases to impress me with their quality boots and great customer service. They run true to size and fit perfectly right out of the box."

— TROY R. (5/5)

Very comfy and durable

"I’ve been wearing the lineman extreme for the last few months and I love them they are very light and comfortable I’ve climbed in them dozens of times on some occasions I’ve been in my hooks for over a hour or more and are very comfortable with the shank no complaints"

— Toby D. (5/5)

Buy again and again

"These boots are of high quality. Feel light weight, fit comfortably from the time on. Whether you’re walking on flat ground or steep drain, they offer great stability and traction. I love the way they fit around my ankle and give it good support especially on those long days. The toe space is great gives enough room to wear thicker sock during those cold days! These have become my go to boots for work, hunting and casual hiking."

— Barbrar O. (5/5)

Would buy again.

"If it fits your feet this is a great boot."

— MARK L. (5/5)

Best work boots ever

"I love these boots my feet stay dry all day and don’t get sore. I am constantly beating the heck out them in and out of trenches doing everything from underground power to overhead. The only time they come off my feet during the day is when I pour concrete to encase all the duct packs we are installing. When I wear the soles out I will definitely be sending in for a rebuild and get another new pair so I have multiple pairs to wear."

— TIMOTHY Y. (5/5)
