Please be advised that the Birkenstock Narrow width accommodates both traditional narrow and medium widths. Add some comfort and warm-weather style to your summer ensemble wearing the Betula Licensed by Birkenstock Leo Soft sandal. Birko-Flor upper is made of acrylic and polyamide felt fibers with a smooth leather-like finish. Features three straps with adjustable buckle closures. Leather-lined, contoured footbed molds to the shape of your foot creating a custom footbed that supports and cradles with every step. Raised toe bar encourages the natural gripping motion of your feet, exercising your legs and aiding circulation. The soft footbed features a foam layer inserted between the cork layer and suede liner. Microscopic air bubbles cushion your feet while providing moderate arch support. Neutral heel profile and deep heel cup keeps the natural padding of your foot under the heel, distributing your body weight more evenly. EVA outsole offers lightweight, shock absorbing support with lasting durability. Heat Warning - Cork footbeds or EVA soles can be damaged by exposure to concentrated heat. Do not leave your footwear in direct sunlight or in closed cars on warm days. If your footwear becomes wet, allow it to air dry slowly, away from direct heat.
