I stand/walk most of the day for work. I've read many reviews of the best boots, police boots, military boots, etc. These are classified as flight boots, but hands down the most comfortable boot I've worn. No break in period needed. This boot is built extremely well. It fits snug. It's lightweight, breathable, and waterproof with the Goretex technology. I preferred a half size below my normal shoe size. I'm an 8W, and wearing 7.5W. I'd definitely take these anywhere where I would need to do a lot of walking/hiking and even running if I didn't own a pair of Nike's. You really get what you pay for, and yes these might be a tad pricier than most boots, but definitely worth the money and built in the USA. The other boots I've recently ordered and tried were Bates Delta-8's Side Zipper (I didn't like them) and Magnum's Response Side Zipper II. Magnum's (best reviewed by Amazon) are the cheapest, super light, and feel good too. The size was half a size lower for me, same thing a 7.5W. If you're looking for a great boot for work because you walk and/or run a lot on you feet, I'd recommend these Belleville's. If you need a cheaper version with a good fit and reviews I'd try the Magnum's.

Note: The side zippers on both boots were pretty useless as it didn't release my foot that well. I still had to untie my boots.

All the military personnel reviews online stated Belleville's were great and I didn't find any criticisms like other boots (Too heavy, etc.)

I will update after some time of use.

Edit: March 7th, 2012. After some use of close to a year, there seems to be a manufacturing defect on the inner part of the right boot near the ball/toes where the boot bends before the rainy season hit. The sole of the boot created a crack that went along about 2-3 inches down the seam. When it rained, my foot got wet. I am very sad, these are really expensive and I expected top notch performance. I used them on a daily basis for 3 months, then quit the job that I was at to start a new career down a different path. So there wasn't a long term strenuous wear on them at all. I use the boots because they're comfortable, on cold days. But I'm disappointed in gear made made from the USA and their policy didn't include my defect. I'd give these boots a 5 star in everything, except for weight and quality. Quality would definitely get a 1 star. The price per performance went down as a crack to me is a defect and now not waterproof.. Go buy the Magnums I previously referred too. They are light weight and just as comfortable. I'm extremely disappointed as most things I buy here in the USA are good, such as Cutco Knives and Powerblock weights.

Edit: March 8th, 2012. As per warranty of Belleville Boots, Cat5, the seller was able to contact Belleville and return my shoes for a full refund. Cat5 responded fast and was courteous, great customer support. As for the boots, I don't think I'll try another set of Belleville's for now. +1 for Belleville and their guarantee of a 1 year warranty, and +1 for Cat5 for a quick response regarding this situation and their efforts to contact the company. I would buy again if I'm looking for anything in the area that Cat5 sells.
