I like clipping in SPD's for long commutes, long distance riding, fast recreational riding, and certainly when riding a pedicab. Just can't beat that connected feeling and efficiency, IMHO. For shorter/family rides, summer time and swimming holes, etc., I cycle in Vibram Five Fingers and Shimano A530's.
For lots of cycling and walking, I prefer these SPD setups.

The Pearl Izumi Fuel Running Shoes
