Which shoes wears Earl from “My name is Earl”?

They are light nubuck work boots. I believe the ones he wears are made by Wesco, If you find a cast picture where Earl is sitting down (online), and you can see the bottoms of his boots, the sole pattern and logo look like Wesco. Wesco boots are really expensive, but Timberland, Caterpillar and Red Wings all make similar boots.

Michael is right, i saw the Wesco logo on the bottom. I also look for these boots, but i am from germany and i cant get them here.
So if someone knows where i can get them plese tell me^^..thanks
