I am a huge fan of Tom's shoes, but have been trying to find no-show socks to wear with them.  These are absolutely perfect... so perfect, in fact, they should be sold with Tom's!  Theses are NOT chinsy little nylons that are practically disposable, rather they are a slightly thicker fabric, complete with little skid resistant pads at the ball of the foot and on the inside of the heel.  These tiny socks don't fall off my foot and crumple awkwardly to the bottom of the shoe.  They stay put, keep my feet cool/warm (depends on the weather or level of air conditioning in my office) in my Tom's, and are very comfortable.  Also, these are very easy to rinse out in the sink to keep clean and fresh.  I'm going to get a couple of pairs in black.
