Just to say we have scoot boots all around. You were honest and said that because my horse had flare, that the flare had to go before they would fit. I took a chance and bought them anyway and I have to say, they stay on brilliantly with no twisting or losing them at any gait - in spite of the flare!! As the flare grows out, no doubt our sizing will change, but this is for a navicular horse who is going from strength to strength hacking and loves his Scoot Boots!! There were other makes he wasn't so happy with which have been sold. And so easy to clean - chuck them in a bucket of water!! So big thumbs up for Scoot Boots!!
