If not using toe clips then use double sided pedals. I like the VO Touring pedals as being light weight, good looking IMO and fairly reasonably priced. They have enough platform area so can be used comfortably with soft soled shoes and can be used with toe clips too. The MKS Sylvans are a decent pedal too for no toe clip use as are many BMX and downhill dual sided pedals.

I see absolutely no point in putting up with single sided pedals such as quill and track pedal designs if not using toe clips as they are pointless for such use.
