I usually tap them on with a rubber mallet! I admit they are a bit of a struggle, but they are the best boots I've found. At least they stay on the horse well for me!
My Mustang didn't fit the shape of the Easyboot Gloves at all. The Epics are basically the same shape, but because of the cable system I can get them good and tight any they stay on anyway. I have even used size 2 boots on horses that should have been in a size 1, and still managed to keep them on long trail rides.
I thought the Easyboot Bares were a BEAR to get on and off. Much harder than the Epics! And I loved the ease of the Old Macs, but the soles started cracking after only two trail rides.
So that's why I am sticking to the Epics. And Easycare has been good to me in the customer support department. I really can't complain, other than the cost of the boots!
Now replacing the cables is also a pain, but I have only had to fix, I would say 3-4 cables in 5 years of using the boots. So that's not too bad. I was able to find the cable at The Home Depot. They also had some small cable clamps to clamp it with, but they are a little bit larger than the ones from Easycare. But if one isn't concerned with looks, you can jerry-rig a new cable with supplies from Home Depot.
