Really good work boot for the money
Size: 11 Wide
Color: Dark Beige
Really comfortable with inserts and definitely sturdy work boots! I work around oil and grease spots on the flooring, definitely slip resistant!

Great Heavy Duty Work Shoe
Size: 9
Color: Dark Beige
I've worn the shoe often over the last six months and have been very satisfied with the fit, quality, and ruggedness of the shoe. Good fit out of the box, but it did take a few times wearing them to break them in and obtain a more comfortable feel. Good quality heavy duty laces and I like the hooks for the last couple rows. Steel toe and thick rubber sole provides additional confidence that the shoe can take on all challenges. I recommend the CAT Men's Diagnostic Hi St Work Boot.

Wonderful Work Boot
Size: 10.5
Color: Dark Beige
We shopped for weeks looking for workboots that are comfortable...I'm certainly glad we waited. These Caterpillar Diagnostic Steel-Toe boots are everything we were looking for: Waterproof Steel Toe Arch Support Thermal Insulation Padded Shaft Leather exterior No-Slip Sole The padded shaft is extremely comfortable and the insulation adds to the "cushy" feeling without causing feet to be hot. They lace quickly and look nice on. The only question is if they will hold up - but only time will tell that and we've only had them a week. (I'll update this comment later about that)- If you are looking for a good workboot, that really is comfortable on the foot, then this is an excellent choice. My husband is on the jobsite 8-10 hours a day, walking on all manner of surfaces. He's very hard on workboots and we've bought a lot of them over the years, some have been good, others have not. But he's so happy with these, when they wear out, we will buy another pair just like them.

Great boots, but they do have a moderate arch
Size: 12 Wide
Color: Dark Beige
I really wanted to like these boots, but they just don't work for my feet. I made it about five minutes before needing to take them off. Definitely not Caterpillar's fault... these boots look nice and seem to be of great quality. I just have funny feet. I did my research beforehand, looking specifically for steel toe boots that will work with feet that are both wide and flat. These boots nail the 'wide' part 100%, at least in the toe area. I've had problems with steel toe boxes being too small before, grinding into the side of my toes with each step, but I had plenty of room to move my toes around when I tried these on (even wearing thick wool socks!). Unfortunately, 'flat' is where I ran into a problem. Several reviews from fellow flat-footed purchasers were encouraging. Unfortunately for me, these boots narrow a bit behind the toe box and do provide moderate arch support. Usually that's a good thing, but I have wide feet that are REALLY flat. Like, when I get out of the pool my wet footprints look like fake Bigfoot impressions on the concrete... no arch, no gap at all. If you look at an arch-side view of the boot you can see where the sole has a curve in it. After reading reviews I was hopeful it was just there for appearance sake and they were wider and flatter inside than Kansas. Nope... that's actual arch support molded into the sole itself, and with the construction method used on these boots it will never sink to conform to my flipper-like feet. The search continues...

Built to last
Size: 12
Color: Dark Beige
I've had these boots for almost 2 years. Wear them every workday in a warehouse doing warehouse stuff. Boot has never disappointed. Almost took them to climb Mt Shasta they're that good. I didn't, of course, but the thought did cross my mind.... that's how comfortable and durable they are. Good buy.

Comfortable AND Lightweight
Size: 10.5
Color: Dark Beige
Best steel toes I've had in 20 years. No real break-in needed. Excellent rubber covered toe box with a comfortable amount of room. I added arch supports like I do for all my work boots. Look great, too. Can't speak to durability, but craftsmanship seems solid. CAT nailed these steelies. Nice work. I work for an international competitor in the heavy equipment business, but still worth it - a case of the best product being selected here, regards of name tag on the product. Kiddos to CAT! 🐈
