This was a great article and I have used Gore-Tex socks (which might work if they weren't so tight), am very interested in the Seirus, and have untested neoprene (so I guess my personal sock situation was understated). Really, I meant in the non-storm, general, fair situations; is there anyone who goes around in two pairs).
But shoe size should consider these fine extra sock suggestions. With my old shoesize, I've had three pairs on (Gore-tex over) but I just odered two Inov8 choices down 1/2 size so I wouldn't have to go around in two socks all the time. The 280's (tried and trusted) feel like an extension of my foot with one sock, but the 290s (never before tried) could fit, and feel as if they need (for my foots protection) two pairs, and a break in period. That might make a better shoe for shoulder and fourth season when you want all those socks on.
Last mid-Oct with two and three pairs of socks on, my feet looked like I'd been to the spa after a 15 mile a day multiday.
Nathan's idea of a single medium to heavyweight sock appeals to me, but I'm really stuck on those Injinjy toe socks and they only come so thick.
My sock gripe is tight band at the top and I've been know to cut these off and seek out the few among many that aren't constructed thusly.
