Most English makers do wider fittings, and some like Church's, C&J and EJ do wide and extra-wide. Be careful, as they represent them differently (I accidentally bought a "G" C&J, mentioned above, not realising that their medium is "E" like Edward Green's, and their "G" is extra-wide; Church's, Barker, Cheaney, Loake and Grenson use "F" as medium and "G" as just normal wide, with Church's also doing an "H"). I have to say the best range of sizes I've ever seen is Allen Edmonds. Who of course, being American, use E as wide and EE or EEE as extra wide. So, er, check your size.
But I do get these rubies for sure. I understand the Simpson last is quite slim, so they might be waiting for your call, Nuke!
