Even if you've worn these since the 60s, 70s, or 80s (as I have), do yourself a favor and DON'T order these online.  They're smaller than they used to be and after wearing them for decades they no longer fit (too narrow especially).  Not only are they hard to find in stores now, but now that most people will be ordering them online they changed the sizing.  Worse, if you order direct from K-Swiss they will take a return but will deduct $5.00 unless you do an exchange.  I'd exchange for a 12 wide but they don't have one listed on their site for this shoe, nor on this page as of this writing.  Too bad, because I really liked them for 30 years.
