if you have to have Kangaroo, them perhaps LL Bean would be an option. In addition there is Russell. I doubt you will run into many others wearing Russell’s. 😀
I looked at the Bean Roo' boots but the reviews were really bad with both quality and waterproofness. Surprised as I have generally had very good experiences with Bean stuff. My bird vest is Bean and getting pretty ragged but it's 25 years old!
I have a pair of Russell dress chukkas and they're OK but the wait and the time to break them in was forever! They're comfortable now but I swear I must have worn them to work for a year before they felt good.
