Well, back in the day, the direction to which this thread may veer was a full three pages of responses filed under:
NukeWorker Forum > Reference, Questions and Help > Nuke Q&A > Work Shoes
BZ's general observation on Internet forums/threads etal, By the 5th post in any thread it starts drifting off topic. By 12 to 15 it has nothing to do with the original topic and if it surives to 30 or so it magically gets back on topic. This applies almost everywhere.

NukeWorker Forum > Career Path > Outages > Are these shoes acceptable for outage?
I'm not sure why safety shoe or boot selection is found in the career path category unless the notion is that if the OP makes the wrong selection of PPE, then the OP's career may be rather short?!?!?!?
Then again, in those three pages of discussion which spanned seven years no one ever suggested to anyone to check with proper authority to know which shoe or boot was required at a minimum for any particular site,....
So the OP does get credit for asking a question which most likely has not been asked before,...
Whether the OP checks back in to review the best correct answer to the OP's question remains to be seen,...
