Features of the Birkenstock Bilbao BF

• Anatomically shaped PU footbed
• Upper: Birko-Flor® (synthetic blend)
• Cover sole: suede
• Sole: PU (polyurethane) outsole, oil and grease resistant

Upper material: Birko-Flor®

Birko-Flor® is a skin-friendly, tear-resistant and easy-care synthetic material used exclusively by BIRKENSTOCK.

Inner sole: Leather cover sole

The skin-friendly, flexible leather cover sole gently nestles against the foot and adapts to its contours. The open-pored and thus particularly breathable surface enables a pleasant foot climate even during heavy physical activity.

Footbed material: Polyurethane

Polyurethane (PU) is a flexible, water- and dirt-repellent synthetic material and makes the shoe particularly easy to clean.

Outsole: Polyurethane

Polyurethanes, also known as PU in the vernacular, are synthetic materials that are ideal for outdoor use. The synthetic material is water and dirt repellent and very easy to clean.
