The design of the BONE sole is inspired by the streamlined lines and tooth-like elements of the spine; the upper is made of hand-stitched patches and metal buckle elements to highlight the craftsmanship details, giving the shoe a trendy outdoor attribute and becoming a personalized item in autumn and winter; the exaggerated sole shape is equipped with midsole TECNO-PIUMAX lightweight foam technology, bringing a flexible and comfortable wearing experience.
