The calf leather has undergone a glossy finish, obtained by spreading a uniform layer of dye and brushing it by hand. The leather sole has a small rubber island so, together with the integrated sole, each step will be more comfortable. You will love being noticed. Made in Montegranaro (Italy).","images":["https://cdn.shopify.com/s/files/1/1627/0215/files/01_martingala_n.jpg?v=1757337091","https://cdn.shopify.com/s/files/1/1627/0215/files/02_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/03_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/04_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/05_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/06_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/07_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/08_martingala_n.jpg?v=1757337092","https://cdn.shopify.com/s/files/1/1627/0215/files/ZX_martingala_n.jpg?v=1757337093","https://cdn.shopify.com/s/files/1/1627/0215/files/ZZ_martingala_n.jpg?v=1757337092"],"price":318,"currency":"USD","in_stock":true,"inventory_qty":119988,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:22.252Z"},"share_url":"https://firestarter.network/l/lst__ceSbnAG","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
