Since being introduced back in 1977, the Boston clog continues to be a favorite among Birkenstock fans year after year. This version has medium density foam added to the cork footbed and under the suede liner, giving it a softer ride and more immediate comfort. A great option to wear around the house, or outside running errands. It’s hard to part with this style once you fall in love with it. Offers slightly less arch support and less contouring to the foot over time than the classic footbed Boston clog.
