{"type":"firestarter.listing","listing":{"id":"lst_tmQNcrER","product_name":"Polentatt","category":"Goodyear Oxfords","description":"You would recognise these Oxfords anywhere: Goodyear welting. In brushed smooth brushed calfskin, with a leather sole, they are designed to last over time: the traditional \"welt\" stitching makes the shoes both resistant and easy to resole. The cork layer between the insole and the sole welcomes your foot: the more you wear them, the more they fit. Wear them with a burgundy striped cotton cream shirt, a silk-and-wool herringbone jacket and flannel trousers with double pleats.Made in Monte San Giusto (Italy)","images":["https://cdn.shopify.com/s/files/1/1627/0215/files/01_polentatt_tdml.jpg?v=1757337234","https://cdn.shopify.com/s/files/1/1627/0215/files/02_polentatt_tdml.jpg?v=1757337234","https://cdn.shopify.com/s/files/1/1627/0215/files/03_polentatt_tdml.jpg?v=1757337234","https://cdn.shopify.com/s/files/1/1627/0215/files/04_polentatt_tdml.jpg?v=1757337234","https://cdn.shopify.com/s/files/1/1627/0215/files/05_polentatt_tdml.jpg?v=1757337234","https://cdn.shopify.com/s/files/1/1627/0215/files/06_polentatt_tdml.jpg?v=1757337235","https://cdn.shopify.com/s/files/1/1627/0215/files/07_polentatt_tdml.jpg?v=1757337234","https://cdn.shopify.com/s/files/1/1627/0215/files/ZX_polentatt_tdml.jpg?v=1757337235","https://cdn.shopify.com/s/files/1/1627/0215/files/ZZ_polentatt_tdml.jpg?v=1757337234"],"price":660,"currency":"USD","in_stock":true,"inventory_qty":79992,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:22.073Z"},"share_url":"https://firestarter.network/l/lst_tmQNcrER","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
