are you talking about glue on plastic shoes? I had discussed this with my farrier and she said that they are just another one of those gimmicks that would be fine for a horse that stays in a stall all day and doesnt get ridden very often lol. They are also twice as expensive, in my area that is. You shouldnt have to worry about rubbing with the boots, one of my friends uses those on her horse when they trail ride on both front feet, and theyve never had a problem like that. We went on one the other week and it was insanly rough and 4 hours long. As long as they are fitted properly I wouldnt see a problem.
