The Birkenstock Clog Boston is a true classic that can be worn effortlessly all year round. Thanks to its two components, the sole ensures a secure and comfortable stance. It consists of a cushioning EVA midsole and a non-slip rubber outsole. The upper material is made of high-quality, soft natural leather. The anatomically shaped cork-latex footbed features a Superlauf sole with a cushioning midsole made of lightweight, flexible EVA plastic, and a non-slip oil- and grease-resistant rubber outsole. The strap includes an individually adjustable metal pin buckle. The untreated surface of the natural leather is visible, and the deep shaping in the heel area supports the foot tissue, keeping the heel bone stable in its natural position, offering almost the same strong support as a closed shoe. The heel bar activates the calf muscles, stabilizes the rearfoot, and improves gait guidance and coordination. Inner and outer longitudinal arch supports provide the foot with necessary stability, while the transverse arch support helps maintain a natural, straight, and firm stance. The toe grips ensure that the toes remain relaxed and spread in their natural position. Width: normal, Size: 35.
