I am known around campus as the girl who wears Birkenstocks constantly. Snowing? Birks. Raining? Birks. Sunshine? Birks. The design of Birkenstocks make them comfortable with or without socks, and they are designed to fit every foot type. They are also unisex, and you can adjust the width of the straps to your comfort. Though one may not see them as winter boots as I do, they are comfortable, stylish, and universal.
