Thanks for the replies everyone. I did some more research. It seems these special pedals are called ''eccentric pedals''. I've decided on simply getting platform pedals since I've been wanting to return to them out of practical reasons.
Stack height is the word I was looking for yes. I currently use SPD SL and it feels my stack height is very high with the decathlon shoes and cleats. I can cut a significant chunk off my saddle height by going to thin platform pedals with thin soled shoes.
Does anyone have a good recommendation for a thin, wide and long platform pedal?
