Ok - first Vass ever. I'm thinking the following: F-last Dark brown calf Berkeley style, i.e. punch captoe oxford Double to single taper JR soles with rubber toes. How does that sound? I have a similar shoe in double to single and, were I to order it again, i would just do a single sole. I enjoy the double to single in a less formal shoe, but in a punch cap I think it detracts from the sleekness of the suit/shoe combination. just my two cents, either way, the shoe itself sounds awesome. i would request a seamless heal, but that is personal preference.
