I am pretty sure those are 995z. 995 is the standard mid-height guidi laceup. The 'z' is from the extra layer on the heel and sole. Not sure about leather or color, but those blue highlights are cool. Edit: eckblk corrected me, see his post below.
@spacepope that stuff is gorgeous. Thanks for the high-quality pictures. Really into the L'Maltieri linen overshirt. Those impossible to find these days? Anyone else doing a similar minimal heavy linen overshirt?
