Hey everyone--I'm looking to do the TransAm tour this summer, and I bought some LOOK (keo) pedals and a nice pair of Carnac road shoes. I haven't attached anything yet (my bike's due to arrive this week), but some tourers have been pushing me more towards mountain bike shoes. Can anyone give me a pro and con about using Road shoes vs using MTB shoes? I only have a few days left until I can return them, so I'd appreciate any help and opinions.

Thanks!
