I love these Red or Dead Mountain boots...

I have horrid ankles and calves, and something about the ankle height and width just works in a way that no other ankle boot has ever worked for me.
But...
I had a black pair that lasted me a good two years. Last autumn I got a brown pair and the zips gave up after about a month. I got a replacement, and the zips on these gave up this morning, about four months after getting them 
Does anyone know of an alternative that wouldn't need replacing so often? I can't really spend £80 on replacing my boots so often!
