I have a hybrid bike and am going to purchase a new road bike (this will be my first), most likely a Trek Emonda ALR 5. I'm open to other suggestions in a similar price range.

Before purchasing the new bike I would like to try clipless pedals and was thinking I'd purchase a set of pedals and shoes using the SPD system. It looks a little more friendly for a beginner and If I'm going to crash, I'd prefer it be on my current bike. Can anybody recommend a reasonable setup to try? I've looked at so many pedals my head is spinning. I look at this as one of those situations that I know so little about cycling that I don't know where to start. I've read countless threads and many, many opinions on the different types and why. For me, I just want a decent starter recommendation to get going. Weight isn't really a big concern, I'm overweight and can easily lose 10x what any pedal weighs in a single ride. More of a concern is, I notice my feet tend to work outward on the pedals, clipless should fix that. I'm also concerned about what appears to be a very small pressure point with these. Thank you for any recommendations you may share.
