Red Wing's 2206 6" work boot
Red Wing is known for two things: Durability and durability. The 2206 is the Red Wing boot that is the most most moderate and that makes it the most suited for working. The full-grain leather upper is fully waterproof (for all of the liquid mess that will drip all over your boots) and the insulation from Thinsulate makes the shoe all that much more comfortable. Red Wing's "Horizon" Super Sole is completely "anti-abrasion" and the removable footbed makes the boot easy to clean and care for.
Putting your trust in Red Wing has worked for years and years and it's no wonder that so many people wear the Red Wing boots to work. They are rated for work in Oil/Gas, Electrical, and with Harsh Chemicals. Basically, they can stand up to anything and that's exactly what you need.
