What are the different types of pedal cleats available for cycling shoes?

There are mainly two types of pedal cleats available for cycling shoes: Look-style cleats and SPD-style cleats. Look-style cleats are commonly used for road cycling, while SPD-style cleats are popular for Mountain Biking and indoor cycling. Look-style cleats have a larger surface area for better power transfer, while SPD-style cleats are smaller and allow for easier walking.
