What are the parts of trainers called?

Trainers, also known as athletic shoes or sneakers, consist of several key parts: the upper, which is the part that covers the foot; the midsole, which provides cushioning and support; the outsole, which is the bottom part that makes contact with the ground for traction; and the insole, which offers additional comfort and support inside the shoe. Other components may include the laces, eyelets, and heel counter, each contributing to the shoe's fit and performance.
