Glossary: The Parts of a ShoeBefore diving into our shoe sizing guide, it helps to know a little footwear terminology.
Almost every shoe or boot is constructed with four major components, which we usually refer to in the description of each style:

Upper
The upper is the visible outer covering of the entire top of the shoe or boot above the sole, designed for visual appeal and the proper level of protection. It is usually made from leather or synthetic fabrics.

Insole
The insole is the soft inner layer of a shoe that contacts the bottom of the foot. Designed to cushion the foot or wick sweat, the insole may also be referred to as the "footbed."

Shank
A shank is found only in footwear that requires more foot stability, such as work boots and backpacking boots. This stiff piece is usually made of either nylon or steel.

Midsole
Between the insole and outsole, the midsole is usually a thick, spongy layer designed to cushion or provide extra stability. It is often made of shock-absorbing EVA (ethyl vinyl acetate) in athletic shoes or more durable but less-cushioning polyurethane in work boots and backpacking boots.

Outsole
The outsole is the bottom part of a shoe that actually contacts the ground. This layer can range from lugged rubber on a hiking boot to thick, smooth leather in a dress shoe.
