Since my purchase of Cinderella Carriage Company in downtown San Diego I have had my horses shod with the HOOF-it composite horseshoe. In the past three years I have had no lameness problems related to concussion or horses slipping on the asphalt as the composite shoes aid in traction in all weather conditions.
My Farrier shoes all for feet with the composite shoes. During our busy season the heavy horses will get 5 to 6 weeks of wear from the shoes. One of my lighter horses actually gets a reset from a set of Marathon shoes.
I would recommend any carriage operation to look at the use of composite shows for the welfare and safety of your horses and your fares.
