Amazing boots. We have mud up to shin high and these babies stay on with ease. The super thick and supportive sole cushions your feet however long you are stood in them. A recent farrier, then dentist, then vet visit meant that I was stood for 8 hours straight, and my feet were as fresh as a daisy come the end of the day. The strong, waterproof zip makes the boots easy to get on and off, whether they are caked in 3" of clay or not! Will buy again, and again, brilliant boots.
