Bicycle pedals are often called "clipless" pedals which can be confusing because you "clip" in! "Clipless" refers to toe clips as of old whereas clipless pedals have a cleat that is bolted to the bottom of your shoe. Clipping in requires stepping down on the pedal, much like a ski binder. Some clipless pedals come in a wider width for larger riders. Mountain pedals are dual sided and designed for quick exit as well as functioning in dirty environments. Pedals come with cleats but they wear out over time and you will need to purchase replacement cleats.
