If only I were a richer man... I have some pull over shoe covers. They are cut out on the bottom to expose the cleat and points that make contact with the ground. I have noticed that then on line and local prices are not hugely different (once you put in S&H). I would consider taking your shoes into a shop and getting a pair you know fit right, cover the vents on your shoes, and won't get torn up walking.
