Wearing a low-end MotoBell 11" waterproof boots. Most of the time keeps my feet dry in tropical rain storms but on 1 occasion it leaked which I think I may have fixed it. Unfortunately, it is not genuine leather and the top skin is peeling.
I have a Puma Goretex boots which I got off on a Sale but have not wore them.
Lastly, a waterproof tactical side-zippered boots, which I find it too warm to wear in the tropics. It keeps you dry from rain but keeps you wet from sweating.
