This version of the Boston clog, a classic BIRKENSTOCK model, comes with a shaft in soft, high-quality woolen felt. The clog can be adapted to all feet thanks to a strap on the upper edge of the shaft and a sturdy metal buckle. It features an anatomical cork-latex sole, a wool felt upper, a suede lining, and an EVA sole. Details include an individually adjustable metal buckle. Made in Germany.
