I buy Thorogood boots for work. They really are a cheap boot.
I buy them because they have a cheap model with a side zip.
If you are looking for a high quality boot that will give you daily service for several years, Thorogood is not the boot for you. I get about 18 months out of a cheap set of side zips. (And I don't even work on my feet primarily.)
Danners are outstanding boots, I've owned many pairs. I finally tired of lacing and un-lacing boots every time I stopped home for lunch or to let the dog out. Went to side zip boots and I'll never go back.
