Have used the old tiny netal nailed on cleats in the early 70s.
Used toeclips (steel and plastic).
Used Powergrips.
Used SPDs for 3,000 miles on our tandem. Stoker did not have sufficient float and developed knee issues so went back to clips and straps on the tandem and on my single racing bke.
Question of choice, comfort, easy of walking without cleat.
Hell at our age, we do what we want!
