I’m just reiterating what others have said above…that cleats aren’t made for walking, and that you should keep some cleat covers with you for when you do have to walk in them (i.e. flats, breakdowns mid-ride). From from the pics you posted it’s clear that you’re walking in them way too much. The screws and washers/plates securing them to the shoe aren’t the least bit rusted or tarnished yet. And also word of advice…if you end up getting cleats that don’t have the softer rubber parts…walking on tile or smooth cement floors can be hazardous…like walking on ice.
