Thank you!
For 10D PA I was measured at AE store, and SA didn't tell anything about huge vamp V.
At home I noticed that it's somewhat tight at small toes, but no pain, and having 0 experiences with dress shoes, I decided to try wider shoes and to down compenstate go shorter 9.5E (my regular size is 10D, and judging what people say for last #5 it totally made sense).
But 9.5E turned out to be the same width at toes like 10D, but just wider at heel and vamp.
It feels like I'm between 10D and 9.5E on last #5. I read quite a few topics on "V" yesterday. It seems like on 9.5E strands, quarters are too close considering leather stretches (that's what people say).
I believe I tried 10.5D, and they were roomier then needed. I also got Delray 10D, and that beast is roomy everywhere (vamp, instep, heel), except much needed toe box width.
