'A fantastic warm sock for winter running. Great wicking means your foot does not feel sweaty!'
Strengths: No more cold feet no matter what the temperature
Weaknesses: Not to be worn in hot weather
Overall: These are the best winter running socks I have ever tried. In snow or minus temperatures your feet still feel warm but the excellent support and wicking mean that your foot remains comfortable. X Socks seems to have thought of everything in this one.
