I agree with others who said the dual platform/spd pedals are kind of a pain to find the right side. I prefer the spd's that clip on both sides. Personally I wouldn't bother with clipless. I had a compelling reason (lots of knee issues and needed clipless pedals to really dial in the fit and prevent misalignment problems), otherwise I'd still just be riding platforms.

All that being said, I really love the way riding clipped in feels, and since I've already sunk the money into a couple of pairs if shoes and pedals, I don't think I would go back. But you can be happy since you don't know the difference.

I have to wear dress shoes at work, so I have to change anyways. You can leave a pair of work shoes at work, so I don't even have to think about it.
