Football players wear cleats, these are shoes with spikes on the bottom to give better traction to the person wearing them.
Football players wear cleats when playing, mainly for traction and grip on the field. The cleats dig into the ground to give the player a safe and secure feeling of balance, which is very important and serious when playing on a wet, muddy and soggy field.
Football cleats are designed to help the athlete dig in and resist force against his/her movement forward. They have cleats that are molded mainly horizontally across the shoe to give more front driven support. Baseball cleats also have support for front driven movement, but, unlike football cleats, they also have cleats that are positioned vertically along the side to help better support side to side movements as well. Baseball cleats can either be molded plastic or metal - metal cleats are not permitted in football.
