I used the cavallo sport boot during a 6 month transition period and it was a great experience. My horse was comfortable from the beginning and seemed to handle rocks and rough terrain llike a mountain goat! They stayed on during 2 hour trail rides even through water. Wore them on all four for the longer rough rides and just the front for the shorter rides. Right now Valley Vet has the Cavallo Sport Boot for $30 off! I highly recommend the sports....they are designed for the hoof that is a little longer than wide. Good luck!!!!
