I purchased a pair of non-Heritage Collection 993's in 2011 and LOVE them.  I purchased the same size (including width) of Heritage Collection 993's here on Amazon in the Fall of 2012 and they have not fit the same from day one.  Tough to describe but they don't fit the same laterally and in-general feel to be of lesser quality.  They're still very solid shoes but I do not think they can command the price point they are at any more.

I find myself wearing the old 993's far more than my new ones, despite the older ones having lost substantial cushioning and support over time.  The Heritage Collection 993's simply feel that different.

If anyone else has experienced this same drop in quality with the adoption of the Heritage Collection name, please reply.
