I had a pair of Brasher Hillmasters and they were brilliant and gave me many years of heavy use, until Ieft them mine behind in a carpark...
When i went to replace them I was advised by the sales assistant to avoid Brasher as they had been taken over by Berghaus, and the build quality had declined notably and they were getting a lot of returns. I went for a pair of Meindl Bhutan boots on his recommendation and have been fine, however I also have a pair of Grisport ranger boots which are just brilliant imo. For me they are the perfect fishing boot. Bought them for 60% off in a Johnson Ross sale, but they have proved so good I have bought a second pair and put them away for the future - that's how much I rate them. Waterproof to about 6", warm in winter, cool in summer, great grip, excellent ankle support. Highly recommended.
