You guys crack me up with the trackstanding comments.... If the OP cannot master SPDs how the heck is trackstanding the easier option?

Approaching an intersection with a need to stop: Unclip early.
Restarting at the intersection: Pedal into the intesection with only one foot clipped in. Just pedal unclipped for a few yards until it is "safe" to reclip


It will only be necessary to do this until you are comfortable with clipless. After a while you will be able to unclip at the last moment and reclip on the first pedal stroke.
