I wear Meindl Perfekt boots year around. It has 400-gram Thinsulate. I wear wool socks with them. I don't get too hot in the summer, and never get cold in the winter hiking in snow.

It doesn't get real hot here, so your mileage may not be the same. My feet don't sweat much though. Wool socks seem to be enough to absorb any moisture.



Money can't buy you happiness, but it can buy you a hunting license and that's pretty close.
