Be careful, cuz comfort walking and effeciency on the bike are not the same thing. To get good power transfer you want a stiff sole, but often the comfy bike shoes are comfy cuz the stole is not very stiff. For example, I used to ride with Nike shoes and while they were more comfy they aren't as effecient as the sidi dominators I now ride in. With that said though, you can walk more easily in a mountain shoe than road shoe cuz of the recessed cleat, and if you go with a stiff mountain shoe you'll still get good power transfer. While I am a 'roadie' I ride in sidi dominators, a high end mountain shoe, and speedplay frog pedals, again a 'mountain' pedal which I like for the easy in/out, light weight, and float. TE even has dominators on sale, although I haven't checked the size availablity. I like a walkable shoe (recessed cleat) since I also tour and commute. In fact, I did hike around in Mexico in my sidis just fine, and find them very comfortable despite the stiff sole. Like anything, fit is also really important for comfort, and tthe dominator has a buckle at the top that helps you lock in the fit with. I don't recommend the dual sided pedals. I also had them on my bike friday, but they are heavy and the spd cleats bothered my knees. Also, you also have to worry about finding the right side.
