What is a "sneaker"?

A sneaker, also known as a trainer or athletic shoe, is a type of footwear that is designed primarily for sports or other physical activities. Sneakers are typically made with lightweight and breathable materials such as canvas, leather, or synthetic fabrics, and feature a flexible sole and cushioned insole to provide comfort and support during movement. They may also incorporate additional features such as reinforced toes, arch support, or shock-absorbing technology to help prevent injury and promote optimal performance. Sneakers come in a wide variety of styles and colors and are worn by people of all ages for a variety of purposes, from running and playing sports to casual everyday wear.
