Mine didn't come out of their encounter with a cunningly disguised calf-height barbed wire fence too well (generally, I'm of a view that anyone who uses barbed wire deserves to have it noosed around their nuts and yanked hard). Slapped loads of neoprene glue on the holes, but eventually the joins between rubber and neoprene start to go, even on the expensive ones (and the seal at the back, not sure why the entire bottom isn't just sealed rubber). They're comfy though, I spent the winter stomping through ~ 25km hikes in them.
