The Catch pedal from Tall Order, built with a nylon plastic body on a heat treated axle. The axle is the part carrying every pedal stroke and every landing, so heat treating it is the bit that matters underneath the plastic.

The thread is 9/16 inch. Check your cranks take a 9/16 inch pedal and not the smaller 1/2 inch size before you order, because the two do not interchange.
