The BIRKENSTOCK Boston Pro is a true classic that can be easily worn all year round. The sole provides comfortable and secure support with its two components, a polyurethane (PU) midsole and a non-slip, dynamic, and lightweight outer sole, also made of polyurethane (TPU). Additionally, the outer sole is repairable. This clog is perfect for everyday wear in the gastronomy sector. The upper is made of high-quality natural leather that is particularly soft, coated in polyurethane (PU). The PU coating makes the material breathable and regulates the temperature in the clog.
