Agree with Trinity, NM, your horse's feet don't look bad, but yes, they are stretched forward a little & flared. Therefore not ideal for Gloves until that's rectified. I suspect whoever fitted your horse for Gloves measured the base of the feet but didn't consider the flaring. You mentioned using tape in the other thread - that may be an effective answer for you, to tighten up the upper of the boot.
Considering the small degree, that could likely be addressed adequately the next trim, with the walls being dressed from the top a bit more than you probably normally do, but as they start to flare past the halfway point(up), I'd possibly not dress quite that much of the outer wall & give it a couple or so trims to get rid of it.
Anything more than 3-1/4" is too much toe and it can be less. I think my 14.3H TWH's front hooves are around 2-7/8". Three of my four got trimmed today, so I could measure them in the AM. I read that on a credible barefoot website a couple years back but, of course, I didn't save it and can't remember whose site I was on
Your pics taken from the top look shorter than 3-1/4" and I don't see that they are too long for any reason
Walkin, we're not talking length in that direction. I agree, toes are not too long vertically. I don't know what made that website 'credible' for you, but I can only say I disagree with it. Yes, it is interesting to make measurements of your horse's feet and see how they change over time. Yes it is important to consider 'normal' parameters and see how your horse's feet fit or differ from this & consider why. Yes, *healthy* feet have a very 'short' hoof capsule compared to the average domestic horse. However 'normal' does not necessarily mean right for every horse & situation, and this 'normal' has also only been gleaned from an average of horses studied in a particular environment so far as I know(Jaime Jackson's study of desert mustangs?).
I almost wonder if Easyboots aren't made for more blocky, upright feet, rather than bare feet with lower heels.
The reason I say that is I always have to work really, really hard (mallets and hoofpicks) to get Easyboot Epics on my two trail horses. But if I go to a larger size boot they are too loose. So I am always trying to cram them into size 2's.
I don't agree Trail. I think most Easy's are indeed made for low heels & short hoof capsules, aside from Boas. But they are all generally made to fit hoof confo that is longer than it is wide(a pet gripe, esp as original Old Macs were a good shape for wider hooves - noises in the pipeline have indicated that wider boots(aside from the wide Gloves) might be happening...). So as you say you have a prob with his quarters, is it possible your horse has rounder feet than is ideal for these boots? If you have a horse who's hooves are as wide or wider(without flares) than they are long, then Renegades are possibly more appropriate, as you can adjust the length.
One thing you might want to try(Easycare don't recommend it tho BTW) is removing the heel strap with the side clamps from the boots. I did this with the original Epics I bought & found them so much better & easier to use.
Boas and I think Old Macs fit my other horse BUT, even four years ago, my hands had too much arthritis to work a clamp system so we went with the Boas.
Annnd both horses have one size bigger front hooves than back hooves
When it comes to metal shoes, they wore the same size front and back without issue but there was just enough of a difference in them to merit putting a size smaller boot on their backs.
This is one thing I don't recommend the normal horse owner try to figure out on their own. It is well worth the money to pay a farrier or trimmer that carries boots on their truck to come and fit your horse.
Re arthritic hands, Easy Trails & Back Country Gloves are really good for ease of use.
Bigger(& wider) front feet compared to backs is normal. Some horses will also have odd sized front feet, which is another booting consideration, as some boots only come in pairs.
Agree with you thoroughly, that it's best to get boots fitted to your horse by a professional. While boots are generally a much cheaper option than shoes in the longrun, it is easy to make fitting mistakes if you don't consider all factors and cause the whole exercise to be an expensive waste of effort.
