Birkenstock Birko Sport — Two-Piece Arch Support Insole

The Birkenstock Birko Sport is a two-piece insole system built to bring the classic Birkenstock feel to your athletic and casual footwear. It pairs a rigid cork arch-support base with a cushioned foam top layer, delivering firm support and shock absorption for medium-arched feet that want the structure of a Birkenstock footbed inside their own shoes.
