Cork footbeds and EVA soles can be damaged by exposure to concentrated heat or extreme temperatures. Do not leave your shoes in direct sunlight for extended periods or in closed cars on hot days. Keep Birkenstock footwear away from campfires, fireplaces, and indoor radiators. Do not immerse in water. Over saturation can compromise the integrity of the sealant materials. It can also change the look and finish of the materials. If your shoes become wet, allow them to air dry slowly, away from direct heat.
Birkenstock sandals and clogs come with a light coating of cork sealer on the exposed cork edge. This protects the cork and prevents it from drying out. If the cork looks like it is drying out, apply a thin coat of Birkenstock Cork Sealer to protect the cork from the elements. Wipe away excess moisture and dirt with a cloth.
Apply water repellent regularly to protect upper leather from water and dirt. Brush uppers with a Nubuck/Suede brush to pull up dirt and dust and restore the nap. Please bear in mind that any cleaning or treatment can change the look and finish of the materials.
