Vtg 1960 Canadian patrol police motorcycle biker uniform bluf mens boots sz 10.5

They are in good use vintage condition, see picture for more information.....No size mark, but I'm 10 and they are just a touch too big for me....I guess 10.5 or 11 US mens size, but check with the sole measurements...Insole measure 10 3/8", and outsole measure 4 1/4" x 12".....Total height is 17"...Inside circumference at the top measure 17 1/2".....These boots was worn by Canadian police motorcycle patrol....A little detail: 2 zipper handle are different, but when zipper are closed, its not visible, see two last pictures....( item #2)
