I use Look pedals - no particular attachment, just what I bought when I went to try clipless pedals a couple of years ago. My frustration is this... when I am stopped and put my foot down, I find that my shoe slips (because the "clip in" part is relatively smooth plastic). I do the obvious things - avoid wet areas (difficult because I'm in Portland, OR) and stay away from painted pavement, but it is still unnerving. This is the area I'm most concerned about getting an injury. And, I use a 10-year old hybrid so it's heavy... add the panniers I use sometimes and I can be in trouble if I start to lose the bike because my foot slips when I come to a stop.

Any thoughts? I'm not opposed to getting new pedals but prefer to to be able to use the same shoes if I can. I've thought about going to a standard pedal and wear athletic shoes...
