The Birkenstock Women's Kalahari Crosselement Sandals are a variation of the classic Milano with an updated Birko-Flor® Futura upper that is skin-friendly and tear-resistant. The pin buckles have been replaced by hook-and-loop fasteners and the heel of the sole has been reinforced for optimum durability. Perfect for all kinds of summer adventures, the non-slip and abrasion-resistant sole promotes a firm footing too. The polyurethane used is also ultra flexible, water and dirt-repellent.
