I have worn Belleville boots for the past 30 years. I love the fact they are made in the USA, as a former soldier that is very important. I am also a mechanic and am squatting or kneeling alot. I have found all of the boots I have purchased have the same issue, the soles split all the way through at the balls of my feet. I buy two pairs at a time and alternate everyday but they only last about two years before they split. I tried resoling but the soles are proprietary and are not the same and not as comfortable. I currently have two pair I'm about to replace for that reason the 750st and the 600st. They are great if you walk or hike and are extremely comfortable but as a mechanic they do not last.

This boot is the BEST. It was standard issue to me, but I have worn it for 7 years straight now. Almost every day for 2 of those years, including a tour in Kuwait, and literally it doesn't show signs of wearing down. Couldn't be happier.
