I was wondering if anyone who regularly wears silk socks could tell me how they fare compared to wool socks or 70/30 wool/nylon socks in terms of durability. And is anyone familiar with Mazarin socks (sold from Mes Chaussettes Rouges)? I'm interested in getting a pair of mazarin silk socks, but the biggest size is 10.5, usually I wear size 12 shoes. Are the sizes flexible enough for me to be able to wear 10.5s? The socks I'm looking at are these http://www.meschaussettesrouges.com/en/silk/90-green-silk.html Thanks in advance.
