I've worked as a welder for over 18 years and have tried all types and brands of work boots. I've found military boots give the best durability against hard use and hold up well against dirt, oil, and chemicals. I was used to getting 12-18 months of use out of a pair of boots until I friend told me about Belleville boots. I get 2-3 years out of a pair and I have them on 12+ hours every day. They are extremely comfortable and I do like the suede look and feel. I have a pair of these 675 STs that I wear in the winter months and the 340 DES STs for the summer. They are priced well for what you get and I'll be buying Belleville for the foreseeable future.
