I've been closely following this thread and was torn between trying the Golite Sun Dragons and the Montrail Vitesse. I went with the Sun Dragons. I've not put many miles on them yet (just three or four "few mile" walks from home).
Doug says in his review they come with insoles that adjust to three different foot widths. Warning: in my haste to try these out when I got them home, I didn't even notice the variants and just wore them in default (widest) configuration, which doesn't work for my feet at all. I was a lot happier when I added the "normal size" add-on piece.
Again, with just a few miles on these, I have to say that I really like how wonderfully cushiony they feel --- I like this a lot, others might find it too much so (dunno). And the toe box is large; in general I'm a big fan of shoes that are shaped more like feet are.
Size/Volume: Like Doug, I got the size 11/11.5. I normally wear a size 10 shoe and like others I size up for hiking shoes. These are fairly roomy inside, even with the correct insole width, I feel like I have to lace them up fairly tight, yet there's not a whole lot of extra room past my big toes, maybe half an inch or so. Hopefully my feet won't grow much beyond that on long trips ... TBD. I'm fighting off minor heel blisters (from a failed attempt at the perfect shoe) so I've been wearing these with a liner sock *and* a light hiking outer sock. I'm a little concerned at how much volume of shoe there will be when I go to just a liner sock.
Weight: In Doug's review, he says that the size 11/11.5 weighs 14.9 oz --- that must be on a per-shoe basis, not for the pair. At first blush this was surprisingly different from what I found, but out-of-the-box I first weighed mine with the default (wide) insoles and got the pair to be 788 grams, 27.8 oz, or 13.9 oz per shoe.
The difference is at least partly in the insoles, however. The way you convert the default "wide" insole to a normal or narrow is to *add* an extra insole piece on, which of course adds weight. Either the normal or the narrow size extra pieces weigh 19 grams (for both) or 0.7 oz. That gets me to something like 14.3 oz per shoe. I can't explain the 0.6 oz per shoe discrepancy with what Doug reports for the same size --- maybe he wasn't able to clean all the dirt off the soles before weighing them or something (my weights were right out of the box clean). Or it could be a difference in our scales, or variants in factory runs on how much the shoes actually weigh or some combination of any or all of those factors.
I'm looking forward to seeing how well these dry out when soaked --- that and just putting a lot of miles on them are my biggest concerns just now. I wore a pair of water shoes (true mesh uppers) for a few miles one day and these the next; with the water shoes I can literally feel the wind wistle across the top of my socks. Not so with the Golite Sun Dragons; they feel a lot like other trail runners in this regard to me. I hope these drain/dry out well enough, and are durable enough to take as my only shoe on very long trips.
