Birkenstock Super Birki Slip-Resistant Clogs Made for busy professional environments, this slip-resistant clog combines easy-care durability with supportive all-day comfort. The water- and dirt-resistant PU upper features easy slip-on entry and a classic round toe, while the removable anatomically shaped cork-latex footbed provides contoured support. A smooth moisture-wicking fabric lining helps maintain comfort, and the non-slip PU treaded outsole resists oil and grease for added stability. Designed for kitchens, medical environments, and the food industry, the clog is washable up to 140°F/60°C, while the footbed can be washed separately up to 86°F/30°C.
