Bike is a specialized sirrus sport, since I've never used the clipping pedal and shoe set-up I went with some entry level shimano pedals and the specialized tahoe shoe figuring I can upgrade in a year or two if I feel the need. Hit the trail for a short twelve miler this morning and absolutely loved the pedals and shoes. My main intent was to keep the pedals under the balls of my feet since I tend to let my feet creep forward until they are under my arches, obviously they did this but I never realized how much power and speed they add by letting you work both the up and down strokes.
