Cycling shoes are shoes purpose-built for cycling. There are a variety of designs depending on the type and intensity of the cycling for which they are intended. This type of shoe generally has a soft outsole (as compared with a road shoe) and a molded internal midsole. They are shaped more like a street or trail shoe with a less exaggerated "rocker" allowing a more normal gait. The outsole usually has a lugged pattern which is like a day hiking boot and is a compromise between an aggressive off shoe and an old style touring shoe. These shoes have a molded midsole which protects the rider's foot from the pedal and transfers energy more evenly without a pressure point at the exact shoe/pedal contact points. It also allows for the attachment of a clipless pedal cleat and can be more or less walked in normally. There is almost always a rectangular cutout in the outsole where a piece of the outsole material is removed by the purchaser or bicycle store under which is the midsole and two oval slots where the cleats are bolted on. Most of these cleats follow Shimano's "SPD" system.
