I bought a pair last season. They are tough, USIA waders that is. They make them in St. Helens Oregon.
I've heard they are offering several different options now too.
Here are mine.
They fit them real loose so you can layer clothes underneath for cold weather. I don't know all the boot options but, they are open to putting whatever boots you want on them and when/if your boots fail, you can have them replaced. Try finding another wader manufacturer that does that. You can't.
