Ok, so this is a little silly, but bear with me. 2 years ago I bought Garmin Vector 3s pedals whiich Look Keo compatible. ~3 months ago, the cleats had pretty much disintegrated so I bought new cleats. But when I bought the new cleats I bought Shimano SPD-SL cleats. They looked a little different but seemed to fit, albeit very tight for the first dozen or so rides. Now they seem to work just fine, but since now I’ve discovered they are technically incompatible, I am wondering on minuses of continuing to use as is. I know replacement is cheap, but I have a lot f issues with my left foot and hate to make any changes when things seem to be rolling okay. And they seem to be at the moment. Thanks for any moderately serious (or better) advice.
