I have to admit that i am rather ignorant on the topic of hiking socks. I have heard that Marino wool is the thing when it comes to regulation of temperature, and this will become handy in the Andes where there is a remarcably difference between day and night temperature.
I have decided to go both the expermental way and the traditionally, and I will get back with an evaluation:-)
The fivefingers consist of : 90% Perf Dry™; 10% spandex
The traditional 68 % Marino wool, 13% polyester, 12% thermalite, 7% elastan
