Duegi's look like a leather ballet slipper with half a golf ball with a slot in it bolted to the bottom. I'm pretty sure I tossed them or gave them away years ago.

Look still makes pedals, so don't know why someone told you that-other than to sell you something else,

There are a number of different clipless designs. I have the SPD's because they came on one bike and I bought another set for the other one and they are fairly cheap. Plus the shoes I got are pretty comfortable.
