From your original thread: "The 50 metre return involves walking down three flights of stairs. Are they so fragile that that amount of walking is the problem?"

yes. Stairs absolutely demolish cleats. I always walk extremely slowly, sideways down stairs. Get cleat covers if you're walking on stairs regularly. That's why they exist, and they cost like $13

indyfabz I assume he just wore down the cleats to the point where the colored stuff is gone
