Birkenstock is well-known for its anatomically shaped foot bed. A lot of people cannot do without this foot bed and therefore Birkenstock insoles are available. This insole is ideal for flat shoes such as sneakers. The insole does not have the toe grip because this does not fit in normal shoes, but it does have the deep heel indentation which supports the foot in the middle and on the sides. The insole is long-lasting and is made of natural materials, such as cork, to ensure perfect support. The insole is available in the width ‘normal’ and will fit in most of the normal width shoes.
