I have tried a variety of pedal and shoe combinations. FOR ME-I like pinned platform pedals (can cost anywhere from $20-$250) and a sticky soled shoe. I have used a pair of New Balance running shoe and they worked fine. But a good pair of 5.10's or Pearl Izumi's are better. I have clipo-ns for my street bike. When it comes to mixing up the riding styles, I really like pinned platforms.

Everyone is different. I do believe the days of "baskets" (toe clips?) are pretty much gone. But biking is pretty subjective, what do you really feel comfortable with?
