Hoof boots seem to go hand in hand with the Barefoot crowd. Some folks just think their horses are better off bare. I kept my horses barfoot for the past 5 years. I gave up and put shoes back on them for the summer and fall. I still believe in keeping my horses bare as much of the year as possible.
My horses can go ANYWHERE for a day. What they can't do is travel extremely rocky trails 2-3-4 days in a row. So the solutions is stay bare as much as possible and wear hoof boots when the horses need the extra protection.
For me boots are just a PITA. With 4 to 5 horses on most rides. I end up spending 30 minutes putting the boots on and again taking them off after the ride. It seems my daughters and their friends, just never learned to put the boots on. With 4 horses on rough rides, I WILL loose or destroy a boot almost every time I use them. So I found the boots to be more expensive than the shoes.
Keeping a horse barefoot, Especially if you want your boots to fit properly, requires frequent and consistant trimming. So you will TRIM more often that you would if you were shoeing a horse. In my case I tried to trim every 3 weeks vs shoeing every 6 weeks. So if you are not doing the triming, You will pay for twice as many farrier visits for the trims.
Trimming for the avg horses is not difficult and you can learn it. You may or may not have the strength to work under a horse. Trim a couple horses and you will know that your farrier earns his paycheck.
But if your horse has special needs. Let a professional farrier do the work.
$50 per boot and loose one boot per ride,Means it cost me $50 to take four horse out. Even if I don't loose the boots, I always tear gaiters, destroy the screws etc. The picture below is after a 3 day weekend at Bryce Canyon
Rocks just tear the boots apart.
There are endurance riders who complete 50 miles races with boots. Easyboot gives awards out to rendurance riders who compete in races with their boots. So they do work, But I'm not willing to spend the time and effort to Tape, Glue, Foam boots onto my horses.
