birkenstock footwear is designed to accommodate all arches in your foot, providing support and comfort during long stretches of wear. Due to the unique Birkenstock design, determining the width you'll need when purchasing some birkenstock outlet is important to ensuring proper support. Unlike other shoes, Birkenstocks don't list their shoes as narrow, regular or wide. They will use a picture of the bare foot to demonstrate the width size. Understanding which picture is equivalent is to your width is relatively easy.
