Dave, felt bottom boots are used frequently by people doing Fly Fishing. You might try an outdoor store.
Thanks for that Kevin, I will have to look into this next time I go to the city, which at the moment, still seems quite a long way off up here in Scotland, as we are still limited to only being able to travel no more than five miles from home, which in the remote I region I live in, is at least 70 miles less then the nearest city is to me.
Thanks again
Dave
