Certain styles of boots are not recommended for high mileage riding. These include boots that go over the coronet to fasten, such at Boas, Old Macs, Old Mac G2’s (as per Easycareinc.com) and by extrapolation, Cavallo Simple boots. Even with gaiters (a separate neoprene sock), they can cause rubs.
Plain old Easyboots fasten below the coronet and are currently acceptable for competitive trail riding (CTR). They are fine if your horse isn’t prone to overreaching. Also, it requires a good fit, so it helps for your horse to be close to the measurements on the boot. These can be glued or foamed on for a competitive ride. I did have one come off @ mile 15 on a CTR (no glue), but the mare finished the last 15 miles barefoot and was fine. The drag riders found my boot. Now I spraypaint them red so I can find 'em if they come off. The funny thing is that it went from a front foot to a back foot (I’ve got pics), and the mare was too excited for me to pull it and put it on the front. Then it came totally off. Weird.
I think some people are using the Glove style (sans gaiter) with the power strap. These, too, would be acceptable for high mileage or CTR. These can also be glued on.
Then you’ve got a variety of Easyboot styles that have a gaiter attached. They vary by the tread and type of closure. Some people have had trouble with the gaitors causing rubs. I never had an issue with this. They cannot be used for CTR with the gaiter attached, and some of the closures work better in conjunction with a gaiter (e.g. the Bares).
The Marquis are supposed to be very good boots. Don’t know if the bladder is likely to cause a rub in the heel bulb or not. They’re supposed to be decent for jumping.
Somebody on COTH just got some Hoofwings. They wrap over the coronet, but I think all the parts above the coronet are soft and unlikely to rub. Again, these would not be acceptable for CTR.
A lot of people love Renegades. I know little about them, since the dealer near me was unable to find Renegades to fit my horses’ feet. Haven’t tried them, but they are supposed to be easy to get on and off. Don’t know if people have had trouble with rubs.
That’s the rundown of what I’ve seen. I’ve tried Boas, Old Macs, Old Mac G2’s, plain Easyboots, Epics, and Bares. What I like about the Easyboot line is that you can often modify the boot to fit better. They tend to be a pain to put on and take off when the fit is snug.
