I own a pair of the Easyboot Trail boots and a pair of the Easyboot Back Country boots, so I feel like I can give you a good answer about the boots. Unlike a previous post on this forum, I have not lost either boots on my horses in water or in thick, gumbo clay mud. I ride through very rough terrain and we gallop a lot and both the Trail and the Back Country boots stay on the hooves very well, they do not come off. The velcro on both boots is VERY strong and the boots donít even turn on the hoof at all. They are also super easy to put on - all you have to do is open up the boot all the way and slip the hoof in, then you pull the side pieces around to the back tightly and secure them with the very strong velcro. I havenít had my velcro loosen or peel up, it holds firm. I am guessing that if someone has had problems keeping these boots on, they must be improperly sized and maybe they are not pressing down on the velcro to firmly attach it. I have owned every boot that Easyboot has made. The only boots that I have had stay on besides the Trail and the Back Country boots are the Easyboot Edge boots, which have a worm clamp tightener and a padded tongue to keep them on snugly. But if your horse has flared hooves, none of the Easyboots will stay on very well which is very frustrating and results in torn boots or gaiters. I disliked the Boas, they are very clunky, the horses donít travel well in them, I cannot lope in them, and they do come off. Havenít tried the Old Macs or the Cavallos. The Renegades let lots of gravel and sticks get stuck under the hoof against the frog, and their rubber/plastic tears. I love the Trails and the Back Country boots - the best boots to own by far, and they only take seconds to apply, unlike all the other Easyboots. My horses travel really well in them, which they do not do in any other boots besides the Easyboot Edge boots, but I much prefer the Trails and the Back Country boots to the Edge Boots. I was afraid the Trails and the Back Country boots would be cumbersome and clunky like the Boas, but they are not at all. I canít tell my horses are wearing them, except for that they are traveling comfortably sound on rocky terrain. Would I spend the extra money to buy the Back Country Boots? I donít think so. The Back Country boots are made of tougher materials on the upper part, and they look like they will last longer, but really, my Trail boots are holding up wonderfully with no signs of wear or weakness. At first when I bought the Trails, I thought they looked like they wouldnít be very strong and would tear easily, but I was very wrong. They are worn almost daily by a horse that is transitioning over to barefoot and we live in very rocky terrain with thick shoe sucking mud and the Trail boots are staying on with no problems for at least 10 hours a day for turnout. They stay put and donít even twist at all. The Back Country boots are a little bulkier and have tougher material on the upper part, but they donít perform any better than the Trail boots. Really, I think the Back Countryís uppers will last longer than the Trails, but I am impressed by both. Itís up to you whether you want to pay $23 more per boot for the Back County boots. BTW, Valley Vet has the best prices on both models of boots. Hope this helps!
