The casual Birkenstock Uji (normal) presents a refreshingly sporty look and impresses with its practical, individually adjustable buckles. It is ideal for those who enjoy combining sporty styles with their everyday outfits. The upper material is made from particularly soft suede leather that hugs the foot like a second skin, combined with high-quality nubuck leather. This shoe combines different materials. Information about the main materials can be found in our material guide. The skin-friendly, flexible leather insole gently conforms to the foot and adapts to its contours. The open-pored and therefore particularly breathable surface ensures a pleasant foot climate even during intense physical activity. Cork is a renewable raw material obtained from the bark layer of the cork oak. This natural product is heat-insulating and has very good cushioning properties. EVA (ethylene-vinyl acetate) is a high-quality, particularly lightweight, elastic plastic with excellent cushioning properties. This helps to absorb minor ground irregularities and gently cushions the steps during walking.
