Second, there are two different types of cleats: molded and detachable cleats. Most are designed exclusively for either grass or turf fields, so consider what types of fields your child most commonly plays on. If their games are played on both grass and turf, you can opt for a multipurpose cleat. One important sidenote: Some schools, teams, and leagues DO NOT allow Metal and/or detachable cleats, so make sure to ask before you buy.
