I do not believe you (we) are thumbing our nose or asserting our dominance over the masses via our choice of footwear.
These are just a departure from my typical shoe so I was looking for some feedback on their versatility. For some that flash of grey is very subtle for me it it's a little bold and I don't want to stray too far from my comfort zone.
As one who is working on light blue boots and blue/grey and navy/white spectattors, I so go grey! Seriously, whether you go grey or black, the boots you are considering look great and I hope you get and enjoy them - whether you are on the ramparts or the boardroom.
