X-Socks Speed Metal Running Sock - 2009 BCS

I must admit that these metal ones are better than the regular run performance in terms of feel (very thin construction) and temperature regulation. They look pretty cool as well with a metallic sheen. In the shoe these are the best socks out there. They really do what they claim and make just about any endeavor more comfortable. They have less bulk than most other socks. Most sock companies claim to have different materials/construction in different areas for support , etc. but I think X-Socks takes this to a whole new level of precision and performance. I'm not sure where these ones specifically were made, but I know some of the X-socks I have are made in Italy (either these or the Speed Metal). I have used the biking ultralight for years now for biking and the hiking socks in boots and picked up some of these recently for walking/golf. I would advise that they are not the most durable out of the shoe for walking around in just socks. I found them easy to get holes in compared to other brands such as Smartwool and Bridgedale, which have much more material to them. I had lost several right foot socks from the mid-hiking ones before I stopped doing this. At this price you should be careful with them and wash them as per the instructions with air drying only. An occasional one has made its way into the dryer and come out okay though. In the shoe they do seem to last forever. The biking ones that I immediately take off after a several hour ride are still as good as new. It can be a bit confusing with all the different types, so I would suggest trying a pair from several different models until you find your favorite and then splurge for a half-dozen or more pairs if you can afford it.
