I am TTS US9.5D.
I am US9D in AE's Jefferson (AE's 5 last is its longest last, and probably its most narrow, so I size down 1/2 size from TTS).
I am 9/9.5D in EG's 202. EG's D width is slightly more narrow than its regular E width, and many would characterize EG's D width as being inbetween a US C width and a US D (regular) width, a C+ if you will.
In my experience with various EG models and last, I have never gone down more than 1/2 size from my US size. I can and do wear EG's E width as well.
You reckon I could grab an EG 8/8.5E if my TTS is USD9D, yes? Are the EG sizes for the 202 last meant to have a lot of toe room, or are they meant to fit perfectly?
Right now my US9D AE Jefferson has a ridiculous amount of toe room, but somehow my feet fit well and I'm not sliding around inside.
