I'd greatly appreciate a little guidance for a clipless noob. Could you suggests brands that might work best for me and my narrow feet? I have mountain/platform combo pedals on current my bike (weekday communter/weekend rider) but ideally I'd like to buy a shoe that could use on my next bike too which will have road pedals. Are there any shoes that can accomodate road and mountian cleats/pedals? I've searched and learned alot but still wondering about this. About fit, am I right to avoid anything with heel slip (up/down) while walking? Or is the action on the pedals so different that the slip that is manifest when walk-testing the shoes not the most important thing to focus on for fit?
