Of all the active posters here, only a handful (such as myself, sevenfoldtieguy, bakes, ReppTiePoster, sazon, etc) seem to work in environments that require somewhat conservative business dress Monday-Thursday. I only wear commando soled shoes/boots with business attire when it is snowing, in which case you have a lot of leeway with what footwear you are wearing. On casual fridays (which are chinos or wool pants), I will wear some of my commando boots/shoes.
Looks like dovers + leather soles is the better option for M-TH then. Too bad that option is not readily available.
Unlined dovers with leather (flex welt) have been sold in the past and will be sold again. I own some in black cordovan...
FWIW, here are my M-Thurs shoes:
Brooks Brothers Color 8 Wingtip Bals
Black Cordovan Punch Captoe Bals
Cigar Straight Tip Captoe Bals
Color 8 Full Strap Loafers
Black Cordovan Dovers
Ralph Lauren Marlow Wingtips
Ravello Tassel Loafers
The Color 8 PTBs, Marlow Wingtips and Ravello Tassels can play double duty and go more casual.
I'm considering eventually adding a something like the 9751 to this rotation.
