Just wanting peoples opinions on fly boots. Yesterday I decided it was too hot for my horse to wear his magnet boots during the day. As soon as they were off he just stomped his front legs all day! The ground shook from it and drove me mad thinking about his poor leg joints with each stomp. What brands of fly boots have you used? And did they rub at all? Did they make any difference (flies still being annoying above the knee lol)?
