I am preparing to start commuting, hoping to get the bike all roadworthy this weekend. Earlier this last week, I succumbed to an additional 20% off sale and bought some A520s and some road shoes. I'm a newbie and now realize that I should have bought some shoes I could walk in. So, I'm planning to return the shoes and get a pair of mountain bike shoes (still researching which ones).

I'm also considering returning the A520s. The main reason is that I have a torn ACL in my right knee, so I'm thinking that I should get a pedal with more float (Time ATACs, for example). Thoughts / opinions about this?

I am 52 years old and my commute will be quite short - 4 miles one way, but it is quite hilly here in central New York. I also hope to take longer rides to enjoy the fantastic scenery once I get in shape.
