wow lots of comments and pedal ideas thanks. I'm not competitive and not a very strong cyclist, any amount of extra push I might be getting from clipping in would have to be really small, it's always been a foot position thing for me personally. The only reason I started wearing them in the first place was I bought a nice road bike and my big feet were hitting the tire sometimes. I do think that wearing clipless has trained my feet to be in the correct location and for that they were worth the effort. I have the two sided spds on mt MTB and yesterday I rode around in normal shoes trying to pay attention to how it felt. I noticed that with good grip you still get to "Pull" you leg back after the downstroke. I might be doing it wrong but for me I use the downstroke and pull for 99% of my power.

It won't hurt to just try pops and see how it goes. I can always change them out later. While it's usually a PITA being flat footed seems to help me on normal pedals. I flat stiff shoe is actually the most comfortable thing I can wear.
