Slicksurf feet are almost identical, but with more, much more durability. My mx518 still has them on, since about 6 or 8 years ago. And that was my main mouse for 4 straight years.
So they are pretty durable, yes.
Durable isn't necessarily ideal for mouse feet. You actually want a very small layer to be lost through friction to offset any resistance felt.
My favorite skates are pure PTFE teflon (white) without added composites for coloring or durability.
Something along the likes of corepad skatez which do come at a premium
This is subjective but there's my two cents anyway
