The black Birkenstock Birko Basic Textile Regular Fit insole offers the classic shape of the BIRKENSTOCK insole in an inconspicuous design. Contoured all-over arch support stabilizes the foot and helps maintain a natural position, while the absorbent BirkoTex™ lining wicks away moisture and increases comfort. The insole is suitable for everyday shoes, work models and trekking shoes and provides low-profile support without changing the cut of the shoe. We recommend it as a practical gift for someone who appreciates better support when standing or walking for a long time.
