Hello,
as an experienced hiker I`d highly recommend everybody to wear two pair of socks at the same time in their boots. Never mind the heat, it´s better to sweat than to have blisters. I know that you can use even socks made of cotton, but under them you have to have polyester socks. It works, believe me. The problem with cotton is the drying time when you wash then on tour. The same thing goes with wool. If I have to choose between cotton and wool, I´d go for wool, even in the summertime. Two thin layers is much better than one bulky one.
