I realize everyone says to only unclip one foot, but do what is best for you.

I unclip both feet in advance of the stop and pedal on the back of the shoes until I stop. If it is a stop sign and nobody is coming, I don't need to stop and I can then gear up and continue to pedal across the road and clip in while I am crossing the road. If I need to stop because it is a busy cross road, or it is an urban setting with a stop light, I plant both feet on the ground and then clip back in with my right foot; I then scoot back up on the saddle and clip the left foot back in while crossing the road.

The reason this works best for me is because I am lame in the left foot; I shattered the left ankle joint in 1985 and I feel blessed to have enough mobility in the foot to cycle once again. I've only fallen twice in my first 1500 miles of cycling clipless, the first time being on day one of learning the pedals, and the second time when my left foot inadvertently clipped back in as I was braking to a stop.

Just because everyone says you only unclip one foot, it doesn't mean you have to do the same. Always figure out what works best for you, and do it that way.
