Ariat Terrain/Telluride H2O boots - whats the difference?

[Stenners]

I have a pair of old Ariat Terrain H20 zip boots which now have a hole in the toe and look worse for wear (they are about 9 years old!) so I want to get some new ones probably the same but I can't seem to find the difference between the Terrain and Telluride. Does anyone know?
I used to wear them a lot for riding and throw some chaps over the top but I only tend to use them on the yard now but handy to ride in if short of time to change boots!

I think Tell You ride are waterproof. I have very old Ariat Terrain lace ups dual purpose which I love but they are not waterproof. OH bought similar years later and his were waterproof.

Ah I thought they were both waterproof!
