GS - have not seen or used anything else but Korkers, well felt soles has it's place too... My personal thought is that you can find the lace up Korkers somewhere cheap and they work great over the lightweight wader boots used over stocking foot waders. Much more comfortable and lightweight than traditional waders with the boot foot.
With the lace up Korkers, not only are they cheaper but I think a little tougher too (and lighter). The hard strap Korkers are much more coin AND seem to take a little less beating (I need to replace a couple clips on mine). But they are SO much more comfortable with boot foot waders. Not really an isuue with Wader Boots.
I have VERY wide feet, so finding comfort in wader boots has been tough until now...
I would be interested in seeing those other creepers you talk about
