Using cycling shoes with cleat on sole of shoe and clipless pedal makes cycling so much more enjoyable. You have a smoother pedal action, you get more bang for your buck so to speak as you pull on the upstroke as well as pushing on the downstroke, so you don't have to pedal as hard for the same speed. It also makes going up hills easier. I didn't try clipless pedals/cycling shoes until I was well into my forties and now I would not willingly go back to 'normal' platform pedals and 'normal' shoes. Clipping in and out swiftly becomes second nature and is easy to do, even in traffic.
