These feel good on my feet, are not heavily lined but waterproof.  Just what i wanted to take to England next summer, hear that it rains there a bit!  I would not get these for winter boots here in Minnesota, but have used them for quick jaunts out to get the mail and they are functional.  I purchased both the 7 and 8 and the 8 definately fit my feet the best; my shoe size is 7.5 medium.  Will give the others to a friend.
