The Birkenstock Men's Arizona Soft Footbed Sandal is a genuine classic. This individually adjustable unisex two- strap sandal is now available in a sturdy oiled nubuck leather with soft footbed. Footbed lining: Suede. Upper: Oiled nubuck leather -?Oiled leather can be recognized by its untreated surface. Birkenstock purposely does not treat surface grains and other characteristic features. Birkenstock uses sturdy leather with a thickness of 2.8 to 3.2 millimeters as upper material.. Insole: Real leather -?The flexible leather lining, which is gentle on the skin, nestles up softly against your foot and adjusts to its contour. The open-pored and thus very breathable surface makes for a comfortable foot climate, even during more strenuous physical activity.. Footbed material: Cork -?Cork is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning.. Outsole: EVA -?EVA (ethylene vinyl acetate) is a high-quality, very light, elastic material with extremely good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned.. Soft footbed -?The soft footbed has an integrated latex foam cushion. So it offers excellent comfort from day one.. Original Birkenstock soft footbed; anatomically shaped. Strap with two individually adjustable metal pin buckles. Spot clean. Imported - Made in Germany.
