In order to get to the trails, you have to cross some jagged rocks and there is a lot of walking along the cement road. The horses seemed very uncomfortable and they were rushing to get over to the grass - not to eat it, but to walk on it. They were stumbling a lot over the rocks and seemed pretty miserable the whole way.
Their feet are in good condition so I feel bad asking her to shoe the horses, as I've heard after you shoe them once it is difficult to go barefoot again. I know it can shave a lot of the farrier costs off too. It is very obvious that they are feeling discomfort on certain terrains that we need to cross, though, and I am not sure how this will go over the whole summer.
Would it be wrong to ask the owner to shoe the horses? I've heard other people have asked and she has said she wants to keep them barefoot as long as possible.
