I can't decide. I have my old faithful Shimano MTB shoes, which I've had for six years, which are NEVER going to wear out. But now I have my first road bike. Are there benefits to road shoes which I am unaware of, other than, is the deal with the slick soles to make them more aerodynamic? I like being able to get off and walk around if I want to. I am using SPD pedals on all three bikes. I have always coveted Sidi's, and this might be an opportunity to need new shoes. And do you guys like the little buckle things better than velcro, or are they more trouble, and do they hold up well?

Thanks,

Nanci
