I would have given you crap for wearing brown boots as a SMA. You didn't get to wear brown boots until you made HAC at my last command. Did you just go to the PAO and ask because you wanted to wear them or was there an actual reason you need to wear the brown boots.
I know there is a sense of privilege associated with the brown boots, but I think it it a bunch of BS. I wore out 4 or 5 pairs of the black Frakenboots before switching to the brown boots and wish I had been wearing the brown boots all along. (My command wouldn't buy the brown ones for anyone since they were "too expensive." I only switched when I was forced to buy after wearing a pair out and not getting an order to the paraloft in time.) The brown ones are much more comfortable and wear better. The brown shoes LOOK better, but the brown boots ARE better.
Uniform regs say ANY officer or chief can brown shoes with the khakis. I see non-aviation people in brown shoes all the time at it doesn't bother me. Any officer or chief can also wear the brown boots with a flight suit or wash khakis. I know some guys are waiting to get to a command that will buy the brown boots for them, but don't knock the guy who wants to be comfortable.
Wings are earned. Boots and shoes are not.
