3 out of the 4 horses in my field have back shoes. They are required for the work they do but NONE are kickers so it is not a problem. A shoe with studs definitely does alot of damage and if I was in a field with a known kicker I would complain about wearing back shoes.
There is a rule at the barn a board at that the horses in the paddocks with other boarders horses are not allowed to have hind shoes, because even if the horse isnt a kicker, they get palying or if one horse gets grumpy in can be dangorous. A shoe can really do damage, its almost like iron knuckles if you know what those are.
