Don't thank me, another new guy, "tacticalight", brought it up in the "Ultimate Knife" thread, I just ordered one too.

On the subject of footwear: I know you like the shoes you wear, but how far have you walked in them, not over years, but all at once. Maybe standard oxford type shoes work well for you, but the only ones I've found that worked for me for distance walking were Rockports. I really prefer a light hiking boot. Consider wearing a pair during the commute and switching at the office.
