Shimano Cleat Covers
I can't say if these are genuine or not, but I don't really mind if they're fakes. They fit on my SPD-SL cleats, they protect them as accordingly and they'll make expensive cleats last longer. 5/5 - it's cheap, you can store it in your back pocket and you can walk without damaging your cleats while finding it easier to walk, because it's made out of a rubbery hard material.
