The 5 last is long and narrow (IMO there should be no such thing as a "long" last, but that's a debate for another day). AE themselves (and those in the AE thread) recommend sizing down .5 length, and sizing up one width from your measured Brannock size for shoes on this last. I.e. if you normally take a 10.5D, go with a 10E. I myself recently ordered some AE Fifth Aves (which arelast 5). I'm measured as right on the border of an 11B/C. I originally ordered a 10.5D in line with the above advice, but they proved to be a bit too wide, so I've gone with a 10.5C. I have actually heard that Strands are possibly a little wider again than other last 5 shoes, but you should ask on the AE thread for that since I don't own any myself.
