My mare stops flying all day. she breaks her hooves and injures the soles of her feet. it stopped pounding! Love it! She also seemed to like them because she didn't take them off. However, after about 2 weeks, she tore off one hind leg, then the other. On closer inspection I can see where the hard/slightly flexible plastic fin is bent and must have been rubbing against it as it has worn down material down to the plastic fin. I can't blame her for taking it off. I hope I can keep it bent properly so it doesn't rub.
