Okay, I'm having problems getting the right socks (i think). I wear almost exclusively AEs to work (both bluchers and bals) I bought a few pairs of dress socks (some sort of blended nylon material, not cotton or wool) from Gold Toe last week and quickly found that they were too thin, as my feet had more room than I'd like (going down a size in shoes isn't an option). So I went back to Gold Toe and purchased a few pairs of their "bamboo" line made of rayon, a thicker sock. Well I quickly found these too large and "spongy." My feet were sweating all day and the spongy feel was both tight in the shoe and annoying. So today I exchanged them for a few pairs of "Windsor Wool." They are 54% wool and 45% nylon. These seem to be the correct thickness and they don't go up too high (sit a couple inches below the knee). My question is: are these good quality socks that will last, and is wool a good indicator of that?
