These shoes are used for running, basketball, and tennis (amongst others) but tend to exclude shoes for sports such as football (soccer) and rugby, which are generally called “boots”. These shoes have also been tailored for the casual market, and are popular, especially with young people. The terms sneakers and trainers tend to be associated more with the casual use of athletic shoes. These casual shoes are derivatives of shoes worn, and endorsed, by athletes as well as other celebrities.
