Its a whole bunch of little things that suggest they are 60s to me. The buckle being gold instead of silver, the typeface of the printing in the sock liner, and the slogan 'The Personal Shoe FOr You' - that's a very Mad Men 60s thing, the brown finish to the leather sole (I would bet the early 80s shoe would have a black finish to the sole), I assume the monkstrap works - it looks like it does - whereas an 80s version might be purely ornamental, or have an elastic attaching the buckle through the strap so that you don't have to undo it to put it on, the 60s version is cut a titch higher on the foot, covering the instep, while the 80s version would be cut just a titch shorter so you could slip the shoes on, and the curved cut on the inside of the heel - I would expect a straight cut on an 80s shoe. I wore the 80s version myself and believe me I would have KILLED For this pair then (I could wear an 11 then too, although they look too narrow) because the 60s versions were just ever so slightly more finessed in their construction. The 80s shoes used bigger stitches and thicker leather or cruder suede. The 80s ones were often made by George Cox in England who continued making them well into the 80s with thick, Doc Marten soles. I don't think you could find a pair with this pointed a toe made by any Italian maker in the 80s - The Italians were doing Armani looking jazz oxfords in smooth grey and caramel shades in the early 80s, or moccasin loafers - this type of shoe in the early 80s was being worn only by men under the age of 25 who were into neo-romanticisim or rockabilly.
