I've got several hundered miles on my Renegades and yours look fine to me. Don't over think it, just center them on the bulbs and forget about it.....cables look to adjusted pretty good too, might increase it just a bit as the hoofs grow.....
I was and am an Easyboot fan, because it's the only boot I have used and they work well for me. But I though I would try a pair of Renegades. Tried them on yesterday and I love them. So easy and quick to put on. Went out for about 20 min with a brisk gait and no problems.
Yea, I have a pair of easy boots too and there a fine boot but the Renegades are easier to get on and off.
Renegade says not to put them on to tight, but I like mine a little tight.
Not the top strap, leave it loose.
What I found is you want the same amount of cable on each side (bottom adjustment). If you just pull the strap then one side takes up the slack and the spacing is uneven.
So lets assume the tag end of the strap, when the boot is installed will be to the outside of the hoof. Like you have it in the picture.
I use a hoof pick and slip it into the top of the inside buckle. While pulling the strap I use the hoof pick to pull the inside buckle so that the boot goes on evenly and the cables are even on both sides.
I also have a little wider spacing on a fresh trim than what's recommended so I don't have to readjust in a few weeks when the hoof grows. On a fresh trim I have probably 3/4 inch when the boots in place. It looks like you could adjust the cable length just a little longer as you don't have much space between the buckle and the boot. This will make it harder to put on as the hoof grows....
Let me also point out, the straps are velcro, and you can adjust the length of the strap to get the tag length where you want it to be without adjusting the cables.
Now, I'm not near as smart as most, so it took me several months to figure this all out....but, the more you use them the more you'll find some short cuts.....
