These boots are very comfortable and lite weight but not made for heavy construction. I work for a company installing natural gas pipelines. We spend a lot of time in the mud, dirt, asphalt and in all weather types sometimes 14-16 hours a day. I wore these boots for around two months before the inside liner started to come apart. The soles were starting to wear prematurely and missing chunks of material. Two of the eyelets had started coming off as well. I would say these boots are made for a foreman who comes out to check the job site periodically. Pretty disappointed for an American made boot.
