UPDATE - Already ripped a hole in the toe in a couple pair of socks.  So the longevity/quality is lacking a bit...
I have to dress up every day for work and was so happy when these socks arrived at my door!  Super nice, rich looking, smooth material.  Fit my size 9.5 foot like a glove.  If by chance anyone would see my socks at work, they now add to the perfect fit of my attire!
