As a truck driver, I am required to wear safety boots. In the past I've had a few "incidents" that have destroyed the tennis-shoe style safety toe shoes (still saved my feet, but was forced to replace them) I've had heavy hiking style boots that just wear out in 6 months or less. I've had others that wear down the outer sole to the point of being racing slicks...very dangerous to wear in wet conditions (again in less than a year) I saw US Boots being showcased on Fox and Friends and decided to give them a try. After 6 months, a couple of cleanings with saddle soap, and a wipe of mink oil. these still are holding up quite well. Even the outer soles are showing minimal wear after walking 4-6 miles a day on rough concrete. The only thing I had to change are the insoles. They did not support my high arches, and caused my plantar fasciitis to flair up again...not blaming US Boots in this, I knew I had to get new inserts. With my custom inserts, a few cleanings, and daily brushings, these have been by-far the best boots I have ever abus...used in a long time. I plan to get another pair of their boots once these give out.
