I agree that Xtratufs are “the boot” in Alaska, and you may have trouble finding anything else. The only good thing about them is the excellent non-skid soles. I’ve worn them a lot, but that does not mean that I like them.
I’ve never seen steel toe safety Xtratufs and they are too floppy to provide any ankle support. They are also easy to puncture. If you have to wear safety boots and/or need to protect your feet - you cannot beat chainsaw boots.
Again, I find the Muck and Bogg boots a lot more comfortable for my purposes (I don’t work on deck), but they do not last long doing serious work on deck. I definitely would not wear them for commercial fishing.
