The rubber covers are a bargain in my opinion. I will never be without them again. I wore down my first set of campy cleats and bought new ones and the guy convinced me that the look cleat covers fit well enough. He was right, I love them, they make life so much easier and I love clips. My pedals have tones of float and I noticed that since my leg operation I have developed a right duck foot somehow. Even with my slotted cleats cranked all the way to compensate I still couldn't get my right foot comfortable. I am sad I may not be able to use slotted clears... I may try filing the holes to add some more range of adjustment though. Clipless pedals were are a bigger performance enhancer than brifters in my opinion.
