I work 12 hour shifts (5 Days per Pay Period) for an EMS organization that runs approximately 11,000 calls per year in a mostly rural environment. I bought these boots for their specifications and at was disappointed with my purchase. Not even one year later my boots are completely worn and in desperate need of replacement. Not even one month into use the toe of the boot began to show signs of wear and tear - not a big deal to me since I am usually busy. However, throughout the next few months  other items began to separate including the inner fabric lining and soles. If you work for a low call volume service, or do not work often, these boots may hold up longer for you. But for me, this is a major disappointment. I am switching back to Magnum which have held up in the city environment I used to work in.
