So, as most people on here I assume, I have multiple bikes. Mostly fixed gear/track bikes, with a road and mountain bike thrown in the mix. I just recently decided to switch over to clipless pedals, and ordered my first shoe. I went with a road shoe, for aesthetics. The Bontrager Spectre shoe. It has the ability to take both a 2-bolt SPD cleat, as well as a 3 bolt road cleat.

Now here's my question...if I were to get different pedals for my bikes, some road & some mountain...what negative consequences would there be to constantly switch between the cleat styles depending on which bike I ride? I bought some Look Keo Classics, but don't want to be limited to ONLY using Look pedals.

Would it be better in the long run to just buy a second pair of shoes? Or can I go from SPD to Look and back depending on my mood?

Thanks!
