Generally speaking, horses run with bar shoes because they have a foot problem such as a quarter crack. Although they may still win in lower level races such as maiden claimers, etc., it is pretty rare to win a graded stakes wearing a bar shoe. A horse running in a bar shoe won\'t be able to get traction as well as a horse without a bar shoe. It\'s kind of like running in sand at the beach. Having two bar shoes tells you that the horse\'s feet are not in good shape making an instant toss for me.
