I never went clipless (clip-in) even into the 90's I still wore cleated leathers with toe clips and straps. Eventually went to a touring shoe, which I didn't really like.

About 10 years ago I picked up some Specialized Sonomas, without the cleat, and they were nice, but the best shoe/pedal combination I have used are Specialized Elite Touring, without the cleat, that I slide into my old Dura Ace 7400 pedals with toe clips and straps. Gives me all the support of a road shoe, with walkable soles, and they slide in and out like a dream. They have never accidentally come out and there has been no problems losing power on climbs.
