Rated 5 out of 5 by from Comfortable Shoe! I have been wearing work boots for 25 years and this boot is by far the most comfortable shoe I ever wore. It is extremely light and my feet don't sweat in them.

Rated 5 out of 5 by from Delivers as advertised Delivers as advertised. Slip resistance from shoes for crews excellent. They need to offer a wider model

Rated 5 out of 5 by from Exceeded expectations; Weight A++ I work as a front end service associate/bagger/store gopher at a decent sized grocery store. I'm on my feet all day, usually walking around on tile, concrete back room floors, and parking lot asphalt. Stock insoles are comfortable enough, but my arches are funky so I got some inserts and I've rarely dealt with stress pain in my feet and knees since. I'm in FL, so when it's wet, it's WET. These bad boys are legitimately the best waterproofed footwear I've ever owned. The traction and tread style are very robust; I can't remember ever feeling unsteady in these on frozen floors. And the carbon fiber toe is well-worth the extra cost. The total weight of these guys seems heavy on paper, but when you actually wear them around you'll realize that it is distributed just right so as to feel sturdy, yet not like walking around with bricks on your feet. Highly recommend!

Rated 5 out of 5 by from Waterproof comfortable boots These boots have been great. They are relatively low profile and waterproof up to the laces. I spray them off with a hose at the end of the day and water has never seeped in. The slip resistance is good. I like the older wide lug style. They were a little bit more slip resistant and cleaning them was as easy as these are so I don't see the benefit of the "Gladiator Outsole" over the normal wide lug pattern, different industries might see an advantage with these, but for food service I don't. Both the wide lug and the gladiator are FAR superior to the old tight style. The laces aren't like most boots of this style. They stay in the boot all the way up the collar of the boot so you have to loosen them a lot to get your feet in versus the laces that you lace up after your feet are in. A small gripe but not a big deal. The inserts they come with are fine. I used them for about 8 hours before my feet started hurting. The arch is too low for my feet although I have a higher arch then most people. After I put different inserts in my feet haven't hurt at all.

Rated 4 out of 5 by from Like a cloud! These last me close to a year in food service although I usually replace every six months due to tread wear which is perfectly reasonable. I get a half size larger than I need, throw the insoles away, and put in ACE PU insoles with a second, memory foam on top.

Rated 4 out of 5 by from Nice Build Great design and durable. Only thing I will say is after 1 wear had to add gel soles. Huge fan of all ACE boots.

Rated 4 out of 5 by from Great book for the cold days Wish I would have gotten 1/2 size smaller but they work great I work out side in the cold all day and my feet are warm all day. Only down side is I may nee do to get different insoles they do t have enough cushion for my liking but would not trade them in for that reason.
