Great article Marsha Cassada! I live in town, I do most of my driving on the rock driveway or on the paved streets. I have contemplated boots for my guys, just because I think it would make them more comfortable, they do gimp a bit on gravel in my opinion, but after watching them more, the gimp seems to come from missteps, not pain. BUT, I am beginning to ask myself if my horses really need all of the things on the market that make this horse-mom go "oh yes, my baby needs that." I have started using slow feeders spread out around the paddock, there are rocks & water hazards between them. Half because I wanted to provide a more "natural" setting, and half because I didn't have any other choice. Some of the articles I've read on barefoot trimming provide some pretty awesome ideas to allow the horse to develop a natural hardy hoof, ideas I hope to implement in the near future. Now that being said, I have had horses in the past who physically couldn't walk on gravel or pavement due to bad farrier work. Time & conditioning, gradually introducing firmer footing did help him some, but he never fully recovered. If you think your horse needs boots, by all means, get them! One good place to find reviews is amazon. I do know there were some threads here too about the best boot, try to search for them & contact whoever started them & see if they followed through & what their thoughts were. I know I didn't answer you original question, but wanted to add my own input as well. Best wishes!
