Those of you who can wear shoes completely barefoot, well, you probably aren't reading here.  I just can't wear shoes barefoot, I get blisters, my feet sweat, etc.  I also work in an environment where sandals really don't work in summer.  So I am so happy these are available so I can keep cooler in the summer.  They are cottony, fit a 9.5 well, and stay up.  They fit well around the toes and are super low cut so I can wear all of my shoes with them and they are hidden almost all of the time; they do a better job than any others I have tried.  They are $5-6 in stores so this is a great deal.
