I bought these at 511 Tactical, Bankstown, and walked out the door with them on because they were so comfortable.
They're ideal boots for my role as a medic in a heavy rail industry.
The A.T.A.C.® 8" SHIELD CSA/ASTM BOOT is superbly comfortable and ruggedly constructed. I would pay more for these boots if it were possible to make them even tougher or more comfy. The side zips are chunky, solid and work well, and the leather uppers are solid and durable and also seem to keep the heat in well during winter (these are not summer boots for me). The soles feel really solid and protective of the bottom of my feet. The conformation of the inside of the sole is curvaceous and locks into the anatomy of the foot exceptionally well (where most of the comfort comes from). I'm really pleased I've finally found what could be my perfect boot, a design that appears to be able to do everything I need it to do, even hiking.
