What part of a shoe is the upper section that is attached to the insole?

The upper section of a shoe, which is attached to the insole, serves as the primary structure that holds the shoe's shape and is typically made from various materials such as leather, synthetic fabrics, or mesh. The upper is crucial for providing both comfort and support to the foot, as well as determining the shoe's style and appearance. It encompasses the part of the shoe that covers the top, sides, and often the heel, connecting securely to the insole, which is the layer that sits beneath the foot.

The outsole refers to the bottom layer of the shoe that comes into contact with the ground, primarily responsible for traction and durability. The midsole serves as cushioning between the upper and the outsole, absorbing shock and providing additional comfort during use. The insole is the interior component that provides additional support and comfort to the foot but does not encompass the entire upper section of the shoe. Hence, the upper is the correct choice as it directly refers to the part of the shoe that is attached to the insole.
