{"type":"firestarter.listing","listing":{"id":"lst_fXIhUGJj","product_name":"Cumenda","category":"Derbies","description":"It's the classic Derby for a best man or wedding guest. It has a wide sole shape and a rounded toe, which is perfect for those with a high instep and wide feet. With its polished binder leather and its three-story leather sole, it’s the black shoe for those looking for a traditional British style, or just love to be different. And the blake-rapid construction makes it very easy to resole.","images":["https://cdn.shopify.com/s/files/1/1627/0215/files/01_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/02_cumenda_nl.jpg?v=1758099382","https://cdn.shopify.com/s/files/1/1627/0215/files/03_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/04_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/05_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/06_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/07_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/08_cumenda_nl.jpg?v=1758099383","https://cdn.shopify.com/s/files/1/1627/0215/files/09_cumenda_nl.jpg?v=1758099384","https://cdn.shopify.com/s/files/1/1627/0215/files/ZX_cumenda_nl.jpg?v=1758099381","https://cdn.shopify.com/s/files/1/1627/0215/files/ZZ_cumenda_nl.jpg?v=1758099380"],"price":530,"currency":"USD","in_stock":true,"inventory_qty":149985,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:22.553Z"},"share_url":"https://firestarter.network/l/lst_fXIhUGJj","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
