Interesting. I sized down 1/2 in the 333 from the 65 and 201. I find it long and wider where I need it (instep, perhaps?). I get much better closure in the 333 than most of my 65s which are a half size longer. Hoping to find out the 1943 fits like that in my normal size.
I've heard that, too, which is why I was so confused about the fit of those Harrisons. FWIW, they were listed on eBay as 11.5 B, but marked 12 B on the shoe itself. Could they be marked wrong on the shoe? No idea. Guy was selling them as a "buy it now" at $40, so I don't know that he seemed like the kind of dude that would know a shoe is mismarked.
