After much internal debate I finally brought a pair of Harkila Blenheim boots. They arrived on Thursday and today was the first chance to use them when out with dogs. I have to say they are the most comfortable boots I have tried and after a couple of hours slow mooching about I felt I could wear them all day long. They are quite expensive but my initial findings are very positive. next time out I will see how waterproof they but will have to wait to see how warm they are.
So far so good
