Hi,

I use Shimano M520 clipless pedals on all my bikes (road and fixed-gear). The only reason I've been using the M520s is because the MTB shoes are great for walking around in, after parking my bikes. However, out of boredom induced curiosity, I've been thinking about trying some more road-bike-specific clipless pedals and shoes. Other than greatly increasing my chances of slipping and falling on my butt, when walking, are there any advantages/disadvantages to MTB specific vs. road specific clipless pedals, in regard to urban/commuting use?

Thanks.
