I discovered Russell a little late into my fascination with footwear, but these have been wonderful companions for hiking and full days on the job-site. Here's some info on the boots...
Signature South 40
Triple vamp chocolate Weather Tuff
Purchased new from Russell's list of in-stock boots (no waiting!!)
Triple vamp green Weather Tuff and green canvas
Poron slip sole
Vibram Multi-purpose sole
Purchased used from eBay.
In all honesty, I haven't worn them enough to test their durability. Russell has a reputation for making durable and long-lasting footwear, so I'm not really worried about that. Overall, I'm a Russell convert, and I'm sure I'll be a customer for life (or as long as I can afford them!). I've owned several pairs of handsewns by Rancourt, Quoddy, Yuketen and Town View Leather, and my Russells feel like they're in a different league, in terms of heft and being overbuilt. That is, Russells feel purpose-built, wheareas other makers focus on aesthetics.
Fit & Sizing
On the brannock I measure 9.5D (left), 9E (right). With medium-weight socks, my left foot measures 10.4", and my right foot measures 10.25" long. Both feet have a fairly high instep, narrow-ish heels, and both feet have a prominent navicular bone.
I prefer the fit of the Mountain PH boots, even though the toes on my left foot are nearly at the end. There's enough room they don't feel crowded, and I prefer a snug fit with moccasin boots. The SS-40s are very comfortable with thick wool socks, too, although I get just a little heel-slip in my right boot. If I had to choose a boot for walking, I'd opt for the Mountain PH. If I was slogging around in mud, snow, wet grass, etc, I'd reach for the SS-40s.
