Just an FYI if anyone is interested.
Somehow the Ag in X-static socks is now considered a form of "Nanotechnology".
Anyways, be that as it may, i've used FoxRiver socks with "X-Static" technology for a couple of yrs now. They do work as advertised - no stink. I performed a "stink" test whose details will remain classified. In a nutshell, it was a shorter duration version of a "stink" test i personally conducted on BPL's PossumDown socks (all in the interest of Science, mind you), whose details will also remain classified.
Another interesting side effect of the thin FoxRiver LinerSocks with X-Static is (and having been very interested in Meridian Theory which underlies Accupuncture and Accupressure and Shiatsu, as well as some MA techniques for about four decades now) that nearly immediately after donning a pair of these liner socks, my feet immediately begin to warm up (sort of an extremely slight, almost unoticeable, "tingly" feeling - even before donning a pair of merino wool hiking socks over them. A very interesting effect to say the least which i think is in some fashion distantly related to Meridian Theory - as Ag is one of two metals (the other being Au) which is used in classical accupuncture to either stimulate or surpress bio-electrical activity (Qi in Pinyin transliteration, aka Chi in Wade-Giles transliteration or Ki in Japanese or Korean) along Meridians or "nerve tracks" (take this description somewhat loosely please as multiple nerves can be involved).
i've tried to deny that this phenomenon is happening and even have switched back and forth right there and then b/t merino liners, p'down socks, and the x-static socks, but it only happens with the x-static socks; very weird and i don't really understand this phenonmenon.
Anyways, here is a link to a Yahoo News article on X-Static technology
