I've just bought my first MTB shoe that has carbon sole. When I wanted to put on the SM-SH51 cleats, I saw that it has some claws, that would (in my opinion) damage the carbon sole of the shoe. So I was wondering, is this what cleat backing plates are used for, to protect the sole against these claws? If so, why don't they just make the clips without claws (probably wouldn't give enough grip to hold it in one place)?
Just to be more clear about what I mean by 'backing plate':
Without these plates, am I going to destroy the sole (because of the claws the cleats have)?
