On the Oak Street thread there's a photo comparison of the Trench boot with the Wolverine, and they're clearly not the same thing. I frankly think the trench is the nicest by far of that genre of boot. It's the least bulbous. The Wolverine at least is much nicer than the Red Wing. The Hamilton doesn't do much for me, but I'd like to see more pictures of the non-shell versions.
I've read a lot about OSB and R, and everyone insists that they are not made by the same people...the factories might even be next door to one another, but not the same. I've also seen nothing to suggest that either is in any way inferior. I appreciate the slightly lower prices at Rancourt, though. I wish they didn't compete so directly, since I'm rooting for both companies and their owners to thrive.
