Birkenstocks allow you feet to assume their natural position, removing all pressure points which naturally increases blood circulation throughout the whole body. Wearing Birkenstocks cause your total bodyweight to become more evenly distributed across your feet. The anatomically correct footbed includes; cuboid arch, lower & upper metatarsal arches, medial & lateral side arches, deep heel cup, and toe grip that will fill in the underside of your foot with true support. The flat design will properly distribute weight which will promote longer wear to help protect your investment. The cork and latex footbed will mold to your feet. The heat and weight from your body will cause the footbed to soften and shape to your foot. Birkenstocks are an investment! Many people wear theirs for more than 10 years. Initial price, a few resoles, and minor maintenance comes out to about $10/year for total comfort and well-being. Some people have been known to wear the same pair for 30+ years!
