This waterproof clog features a durable polyurethane (Birki-foam) upper and a slightly narrower fit than the Profi Birki. Its slip-on design includes a raised back for a secure, clog-like feel. Inside, a microfiber-lined, anatomically contoured footbed offers all-day comfort, while the removable cork insole with linen lining molds to your foot for personalized support. The non-abrasive polyurethane outsole is resistant to grease and acid, and includes a patented angled heel for enhanced traction. Made in Germany for trusted quality and performance.
