Mine feel like they are rocking, and popping up and down as if the insole on your shoe is moving up and down but it isn’t? Tried my shoes on a different bike and they are totally fine, cleat tension is exactly the same as my other bikes, tried it tight and loose no different? Inspected the pedals and they seem fine, no signs of wear at all, it’s particularly bad in the small ring going up hills? They just feel awful, asked my lbs about servicing them but they reckon there’s nothing to service? Using shimano yellow and blue cleats, s works shoes.

I think it would be helpful
I think it would be helpful if you told us how old the pedals were. I take it they are not brand new.

Also, how old is the bike, bottom bracket and chain set? Could be the bearing in the pedal. But this is not likely is the pedal is ‘new’.

The only other suggestion I have, since you screwed the cleat, is check the bottom bracket.

There certainly is stuff to
There certainly is stuff to service on Dura Ace pedals, but it is rare to need to do it.

you would notice any play in the bearings by holding them and rocking, or attempting to rock them.

As said above, move the pedals to a bike that hasn’t got these issues, to narrow down what is at fault. If the fault follows the pedals then they are the problem, if the fault goes away when they are mounted to a different bike, then something in the drivetrain is the problem.

Have you checked the chain-ring bolts are tight on the small ring?
Check the crank arms are tight, try rocking them side to side, and also look for play in the BB.

Yes I’ve tried some other shoes on the duff pedals, Very odd sensation, wouldn’t be surprised if it was my colnago c60 frame/threaded bb design to blame

Have you tried other shoes on the “duff” pedals?

Guessing by “other bikes” you mean other pedals on other bikes. Or have you swapped the pedals over onto other bikes. In which case could it be the crank/BB or even frame that’s the problem?
