The outsole of an athlete’s shoe provides traction and durability, and is designed to meet the specific needs of different sports. It can also provide rigidity for certain activities, but it’s important to inspect the entire shoe when considering a replacement.
The outsole is the portion of an athlete’s shoe that functions primarily as a means of providing traction. Additionally, the outsole reduces the amount of wear that the midsole of the shoe endures. As a result, the outsole also increases the overall durability of the shoe.
The outsole was originally made of rubber or leather, and was modified as necessary to meet the needs of the wearer. A running shoe for a track event, for example, typically had an outsole that contained numerous spikes driven into the bottom to provide traction. In modern times, the outer sole used in a track shoe has a plastic plate molded into it. This makes it possible for the athlete to change the spikes on the bottom of the shoe as needed for each specific track event.
The basketball shoe also benefits from the use of an outsole. The first basketball shoe was made with a rubber compound that gave the shoe a certain amount of cushioning. Unfortunately, this material had a tendency to wear down easily. Also, early basketball players did not realize the importance of traction in the game of basketball when it comes to pivoting and running.
Today, basketball shoes are made to meet the needs of playing on certain surfaces, such as outdoor concrete courts or indoor wooden courts. These different needs are addressed with the design of the shoe’s outer sole. In addition, the sole of the basketball player’s shoe must be able to grip well when the athlete is running, but not when he is turning. Also, the shoe cannot stop suddenly when the basketball player tries to stop. Failure to do so can result in a sprained ankle.
The sole can also provide rigidity to a shoe. A cyclist, for example, requires a rigid shoe. Any unnecessary flexion of the foot results in wasted energy. To keep the shoe rigid, a somewhat inflexible sole is used on the rider’s shoe.
While the sole of a shoe will eventually wear out, designers create them in such a way that they provide the most durability in the areas that get the most wear and tear from normal use. For this reason, the outsole may still be in good shape, while other parts of the shoe, such as the cushioning, are no longer in optimal condition. For this reason, it’s important to inspect more than just the outer sole when determining if new shoes are needed.
