The ‘bows’ that clamp the cleat can wreck the sole of the shoe if there’s not enough shoe tread making contact with pedal spindle (on egg eaters) or platform (other models).
You are less likely to get hot spots if some of the load is shared across the width of the sole. I would have thought. They will rock too if everything goes through the bows.
