Cleats are the missing link between your cycling shoes and your bike pedals. Make sure your cleats are the same brand and type as your bike pedals. Another important consideration is the leeway the cleats have. Especially if you have knee symptoms or other injuries, a cleat with a bit more or a tad less leeway can make all the difference. On road bikes and mountain bikes there are different types of bike pedals as well as different types of cleats.
