The Boston Shearling - Suede from Birkenstock® clog, made cozy for the colder months. Classic suede lends a velvety feel that continues on the inside. The style is fully lined in genuine shearling, right down to the original contoured footbed. A soft, supportive landing every time. Suede upper with a matching adjustable strap. Anatomically correct cork footbed, crafted from cork that is 100% renewable and sustainable, encourages foot health. The shearling lined, contoured footbed will mold to the shape of your foot creating a custom footbed that supports and cradles you each and every step. Raised toe bar is designed to encourage the natural gripping motion of your feet, exercising your legs and aiding circulation. Neutral heel profile and deep heel cup keeps the natural padding of your foot where it belongs, under the heel, distributing your body weight more evenly. Flexible EVA outsole offers lightweight, shock absorbing support with lasting durability. Dual layer Jute wicks away moisture while the bottom adds strength and makes resoling easy.
