Get KoolKovers, rubber covers that fit over the cleat and that you can hang from your toolbag while riding. $15 (pre-COVID). Stops walking wear and makes footing on slippery surfaces far more secure. My cleats die from wear at the pedal and that takes quite a while. Linoleum floors are much more fun to walk on and and I fon't feel the money slipping out of my wallet when I walk on concrete.
