I have owned Earthies before and like the workmanship and quality of the products.  I was specifically looking for this color and they are perfect.  I am a solid 8.5 and these fit but very snug due to the more pointed toe box which you can't tell from the photos.  I live in Houston so I don't need warm socks but I do prefer a thicker sock, I would definately recommend up a half size but I'm keep these...maybe black?
