GUOLUOFEI two straps Sandals

Key Features:

• Design: These are classic two-strap sandals with a timeless design. 

• Upper Material: The upper is typically made from Birko-Flor, a skin-friendly, tear-resistant, and easy-to-care-for synthetic material exclusive to Birkenstock, or in some variations, oiled leather or nubuck. 

• Straps and Buckles: They feature two wide straps with individually adjustable metal pin buckles (often nickel-free) for a customized and secure fit. 
• Footbed: The core feature is the original Birkenstock cork-latex footbed, anatomically shaped to mimic the feel of standing in sand and provide support and comfort. This footbed is made from natural materials like natural cork, natural latex, jute, and suede. 
• Insole: The insole is often made of natural leather or microfibre in vegan versions, recognized by its untreated surface. 
• Outsole: The outsole is made of lightweight and flexible EVA (ethylene vinyl acetate) for cushioning and shock absorption, or durable polyurethane in some models.
