Plain old flat pedals and sometimes loose fitting toe clips. I have tried SPD several times; but I am tired of crashing. I use SPD on my weekend recreational bike; but commuting and utility biking is just too unpredictable.

To those who say "you just have to get used to them (SPD), how many years and how many SPD induced crashes is an acceptable number?

I use SPD where it is appropriate; but I don't use them where they aren't appropriate. I have been using them since the 90s'. I don't find them appropriate for riding in traffic.
