Well I was going to say Calgary's as I have found then to be good everyday boots. If you are looking to replace them, Millbry Hill have them for a good price.
JTE (Just Togs) Montery? I've had my JTE Nebraskas for years, and they've been cleaned about 4 times and are still going strong, but they are quite a formal boot so the Montery might be more suitable?
Or Tuffa suffolks? I have these and they are brilliant
