I have some, they came with my horse but personally I don't think they offer as much protection as some of the others on the market, the fronts are quite good but the back boots don't have the speedie cut shape and also the protection in on the back when I would want the protection on the front of a hind boot. They are padded on the front of the hind but my NEW one had a reinforced strip to protect the front of the cannon bone.
They are definitely good boots, they don't move and fit well but I use them for hacking or indoor XC and have stuck to my NEW XC boots for proper XC!
