This sock is fun and comfy and relatively warm.  Good for dressier shoes too where thickness might be an issue.  The problem?  Holes come much faster than they should.  I wouldn't say I've worn my that much...certainly not enough to warrant holes in the toes and heels.  Yes, the heel has worn thin enough to wear through.  Like I said, I've not worn them enough to warrant this! Get them if you want, but be prepared that it will be a short lived relationship.
