A Mary-jane interpretation of the Spanish alpargatas, the Padua is cut from organic cotton canvas with leather trim and a traditional, braided jute insole. Castañer: Since 1927, Castañer has turned the classic espadrille of humble origins into an icon of sophistication made from natural materials, a timeless classic that never goes out of style. Cotton canvas uppers with sheepskin leather lining and trim. Jute insoles and rubber outsoles. Buckle closure. Made in Spain. Narrow fit. We recommend one size up.
