What kind of pedal do I have and what shoes do I need to buy? Based on my limited research, I think these are SPD-SL clips? But I really just want to know what shoes I can get that will clip into these. I don't ride my bike a ton, so I just want your normal, run-of-the-mill shoes for these pedals.
Those are not clipless pedals and you don't need any kind of special shoes. Those are pedals with toe clips and are meant to be used with regular running shoes.
