The Birkenstock classic Tokio SL has been on the market since the 1980s and has become a classic work shoe for "white-collar" professions. The clog features the anatomically shaped original Birkenstock cork-latex footbed and has a two-component sole. This consists of a cushioning EVA midsole and a slip-resistant, profiled outsole made of genuine rubber. The outsole is also oil and grease resistant. The clog is particularly suitable for daily use in hospitals, medical practices, and the gastronomy sector.

The upper material of the clog is made of soft yet shape-retaining high-quality leather. The clog offers comfort and safety. The closed design of the shoe protects the foot from injuries caused by impacts. The adjustable strap with a sturdy metal buckle across the instep allows the shoe to be tailored to the foot. A heel strap, which can be perfectly adjusted to the foot with an individually adjustable metal buckle, provides additional support and a secure step—even during hectic moments in the workday. All Superlaufsohlen (SL) models are tested according to the EN ISO 20347:2012 standards regarding slip resistance (Category SRC).
