I myself am glad I did try something differn't and my horse has never been more comfortable and happy. How can you say that horse shoes don't constrict blood flow. Let pound some nails on your feet and see how well the blood flows. As with any profession you have your way and others have theirs. Just because for years we have nailed shoes on horses feet doesn't mean we have to.
Wild horses run daily with no shoes on and have no problems.
Matter of fact the foot of a wild horse looks really nice. I just wanted to share my good news about the trim. She isn't nuts. It does work for the horse. Can't teach an old dog new tricks.
