MKS platform pedals, no toe clips, Keen Venice sandals, wool socks. This setup works great all year round for commuting and all the other bike riding I do. I am 53 and ride 5K to 6K miles per year, and don't have any knee pains or other bike related aches and pains. Comfort trumps speed for me, but honestly platform pedals with Keen sandals doesn't make any difference in my speed compared to any kind of clip in pedal.
