Thanks all. I went to REI last night and bought some walkable Shimino MTB SPD SH-M 120G shoes. I had a $39 dividend and got 20% off totalling $108 for the shoes and M324 SPD Shimano pedals. Already went for a ride this morning and have no problems getting out of the shoes (at least not yet). I'm sure this is a heavy combo for road biking, but I do like the idea of being able to walk. And I definitly feel the added power with the clipless shoes/pedal combo.
