Q & As

SmartWool Mountaineering Extra Heavy Crew Socks, Grey 5 5 2 2
The Very Best.... This is my second pair and I wear them for work every day. Very hard wearing and cushion my feet fantastically. These are the best sock I have ever bought, I simply can't praise them enough. I would say they are a true four season sock, just right always. Only bad point is the price - but they do wear really well. 10 February 2013
