I'm thinking of getting some. My forrester keeps loosing his shoes every 2wks. The cavallo ones look quite good and easy to put on. There is lots of info on their website. I think that the different makes fit different shaped feet.
I use cavallos on my forester on her front feet. They look a bit perculiar but she is very happy in them (this is a pony that moonwalks in travel boots) and its great because we don't stumble all the time like we used to..
