The standard for any maintenance troop also. On another note, I used to wear my belvedere flight boots all the time riding before I got some Sidi vertigos I always wear on my extended/spirited rides. Bad, I have those exact boots except my dog chewed up a latch pretty badly. sucks those things were comfortable too. Im not gonna lie, I sometimes wear my chucks when I ride down to starbucks to study or to campus considering I only live 2 miles away...all street/residential area riding. Not the safest thing, but just a risk I take.
