I don't have much to offer that will fuck with your dick CSM. However, I got used to wearing jungle boots while in. I saw these boots at Gander Mountain, tried them on, and fell in love with them. I wear them all the time now. With a gel insole, they are very comfortable and they helped decrease my back pain. I do think they are 670-1 compliant if you are interested. I also have a pair in black I use as uniform boots for my Civil Air Patrol duties.
Reebok is quite a know model within your industry (tactical military, security)
This model has a safety toe cap, but it's composite.
