I don't know if you should be skimping on horse boots as they are things that you will always need. I love the brand Eskradon, but here are some boots that may be good
I honestly don't think these give much support, but they do provide protection
These are pretty expensive but I used them on my first horse and they worked pretty well. It also seems like you like the wrap around kind so....
My friend uses these to jump in. They are pretty nice boots.
These ones don't have a price so you would have to go through that Tell Me More button.
Hope this helps
