You can make platform pedals out of recycled skate decks with a saw, a drill and a wood rasp. The platforms clip into clipless pedals, so you can ride your race bike in sneakers.
I’ve been riding these for about 5 years, almost exclusively. They’re the most comfortable pedals I’ve ever ridden, by a wide margin, and very grippy in all conditions except slick mud. Plus, they let you switch your pedals from clip-in to free-pedaling in about four seconds.
