Couple of issues to explain why it will never work....

The original page (safety-footwear-rigger-boots-c-6_32.html) still works

The original page (safety-footwear-rigger-boots-c-6_32.html) carries the same string/category assignment as the old (safety-boots-rigger-boots-c-6_119_32.html)

The flaw, which has always existed in USEO is that the following urls will ALL load the same page.....

safety-boots-rigger-boots-c-32.html
-c-6_32.html
something-something-something-c-6_119_32.html
