5.11 Tactical A.T.L.A.S. 8" Side Zip Boot - TacSource US 8
Side Zip is a performance boot built from the sole up to increase performance. The All Terrain Load Assistance System is a force multiplier for those who carry heavy weight on long shifts. This boot is constructed of nylon with high abrasion air mesh, a water resistant leather upper, and because so many arduous jobs demand it - a polishable toe. Additional features include a YKK side zipper and a locking ankle eyelet, and a high traction outsole so you can take those corners in a foot pursuit or run headlong into whatever challenge you’re up against.

I’m a state correctional Officer, and spend my 8.5 hour shift on my feet most of the time walking or running around the compound. I normally wear a size 12 and the side zip is extremely important for me because I have to take them off every time I come in and out of the control room which is at least at the beginning and at the end of every shift. I will say that I have thoroughly enjoyed these boots. I’ve had them now for two or three months now. Although the first week or so they were a bit uncomfortable and I did have a little bit of pain across the foot and on the inside zipper I chalked it up to just a break in period. Which after a few days the boots did break in and now fit great and are very comfortable to run and walk in.

The boots are good. At first, I thought they were a little flimsy compared to my previous 5.11 boots, but after I wore them for a shift they held up just fine. They are light. A little snug getting on, even with the zipper down, but I think that is more an issue with my ankle that the boot. Very comfortable and they feel great so far. Good boot for the price.

I just got my pair of the new A.T.L.A.S. Boot a week ago and after that time I feel that it is definitely worth a try. Short version: they are an adjustment but if your willing to adjust to the different feel they will not disappoint you with a superior performance.In detail I believe these are much better than my last boot. For reference I used to wear 511's A.T.A.C 2.0 8" Side Zip Boot. Compared to my last boot the fit is much loser around the ankle and leg, but this comes with the bonus that they are much easier to slide on and off without untying. As for the the heart and sole of this boot, the A.T.L.A.S. system, it was a huge adjustment. Initially I didn't like the feel of the boot especially as I traversed different terrains, but after adjusting to the ... MoreI just got my pair of the new A.T.L.A.S.

On top of that, during the winters this boot does perform better on slippery surfaces such as ice and slush. While it may not be complete traction it is noticeably better, especially on slightly slippery surfaces as a small slush puddle. Only downside so far is the Velcro strap that goes over the zipper has a tenancy to lose grip. Overall these boots are, in my opinion, so good I had to write my first review on them and I would highly recommend them if your willing to adjust.

Love it. This is my second pair. I highly appreciate and recommend the ATLAS technology. It made my life much better especially since I spend long hours on my feet at work. It made a significant improvement over the previous brand I used even though it was more expensive. These boots significantly decreased work-related muscle pains.
I have had these boots for over two years. Yes, I should have replaced them a long time ago, but that’s why I’m writing this review.My soles have been dead for a while, however the outside of my boots still look brand new. Honestly, I could throw some Dr. Sholles in there and keep going and unless I’m standing on hard ground all day, I don’t really feel the discomfort.These boots are durable, they last, and even with me procrastinating replacing them- they have held up just fine.I started looking for other boots to try a different brand out, but honestly I ended up just buying another pair of these.
I needed new station boots and was looking for a new boot to try. These started off awesome as many before have said, there really isn’t a break in period. They start comfortable and are light weight. The problem is that they fall apart quickly and are not up to the task of Fire/EMS. Less than a year of having them the insides fell apart, the zipper disintegrated, and the sole now makes the most annoying clicking noise. For the price I would not recommend these boots. Good start but boots shouldn’t fall apart this quickly.
Can you please stop putting side zippers on all your boots or at bare minimum make a non-side zip version. I’ve always had side zippers fail when I needed a durable boot and nothing you can say will convince me otherwise. Not everyone who needs black duty boots can have, need or want a side zipper.Additionally, not everyone is a cookie cutter mold. I’m 6’5”, 275lbs. I fluxate between 15EEEE to a 17EEE shoe depending on the brand and cut. This is one of first boots I’ve seen in a long time that has an ergonomic shape to the foot box. But it still falls into the trap that all you footwear manufacturers rather pride appearance over fit, functionality, durability, and support.Stop discriminating against individuals who need wider and/or bigger sizes.
I ordered the wrong boot online, went to the store in Thornton, CO where the staff was very helpful and helped me get the boot I was looking for. For a boot under $200 there is no beating the 5.11 AT. My last pair lasted me over a year where boots over $200 fromOther brands made it maybe 6 months. The arch support, cushion, tread, design for comfort and overall durability are fantastic.
These boots offer a good balance of relatively light weight and decent ankle support. I have very bad ankles so support is important and the side zip is great for me. I'm not concerned about speed as much as ease of on/off. I don't have to unlace them all the way each time. I walk a lot for my security job and the Ortholite foot bed is like walking in a sneaker. Great boot.
Thus far 4 stars. Still in the break in period though so it may improve. For walking with load it has been great esp in full gear for law enforcement. But if you are standing for long periods of time I feel the atac is better. Again, this may change. If you need a lot of ankle support like me this boot is ideal.
