UPDATE - 1 month and several washings later.  These socks are much better.  They seem to have shrunk a small bit and have become more comfortable...but they were OK before.

I wear a size 10.5 to an 11 depending on the shoe.  I ordered the smaller size (6-12.5) because I prefer a snug fit.  These socks are almost loose on my foot.

The quality seems OK for the price, just wish these ran more true size.  Seems to run big.
