{"type":"firestarter.listing","listing":{"id":"lst_yVTqWiGO","product_name":"Giacalustra","category":"Oxfords","description":"It's an Oxford for the man who’s free to wear colors other than black. Its aesthetic is both classic and versatile. With its natural hand-dyed leather and its leather sole, it’s the minimal brown shoe to wear at work matching a sartorial gray suit. With its blake-rapid construction, it’s always pretty easy to resole.","images":["https://cdn.shopify.com/s/files/1/1627/0215/files/01_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/02_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/03_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/04_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/05_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/06_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/07_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/08_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/ZX_giacalustra_mc.jpg?v=1757336521","https://cdn.shopify.com/s/files/1/1627/0215/files/ZZ_giacalustra_mc.jpg?v=1757336521"],"price":372,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:18.521Z"},"share_url":"https://firestarter.network/l/lst_yVTqWiGO","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
