I have a bike that came with some Wellgo wpd-800 clipless pedals. The problem is I have no experience with clipless, and no cleats to use them anyway. Is it cheaper to just buy shoes, or can you buy new pedals and shoes as a combo for around the same?

I understand the benefits of attaching your foot to the pedal but I am don't know how practical it is for me. I will probably commute on this bike, so how practical are the shoes that work with these pedals? Or should I plan on keeping a set a regular pedas, then threading the clipless pedals in only when I plan a longer joy ride.
