i never said that 'F' widths were made for the US market . . . i was only concurring with isshinryu101's comment that UK sized, F-width, Santoni 'Fatte a Manos' made for the European market, run very large, and as a general rule of thumb i have found it best to size down 1.5 from one's US size . . . in this sense, they are similar to tricker's on the 4444 last (in many persons' experience). i however, do concur with your thoughts on C&J sizing, as practically every last i've tried has resulted in me dropping down 1 full size from my Brannock 11D US measurements . . . cheers as well, for the lovely collection of photos that you've posted on this site . . .
