{"type":"firestarter.listing","listing":{"id":"lst_ncgfyol4","product_name":"The Hummingbird Mary Jane - Vintage Gold Metal Leather","category":"Flats","description":"A shimmer of golden hour with every step, introducing the Hummingbird Mary Jane in Vintage Gold, a shoe that bends, cushions, and turns heads. This shoe is a step above the rest because the strap includes hidden elastic, so you can slip in without unbuckling every time. Think of the buckle as an adjuster so you can get a custom fit — set it and forget it. This silhouette was crafted with our Barefoot Ballerina technology, which includes a completely flexible leather-lined footbed that bends with you as if you are barefoot, but still offers full arch support and seven layers of cloud-like comfort. The flat is complete with our signature grosgrain backtab and onyx Birdies logo, as well as an onyx buckle.","images":["https://cdn.shopify.com/s/files/1/0775/7215/files/HMJ-MTG_WEB1.png?v=1758565385","https://cdn.shopify.com/s/files/1/0775/7215/files/55.png?v=1763077032","https://cdn.shopify.com/s/files/1/0775/7215/files/HMJ-MTG_WEB2.png?v=1763077032","https://cdn.shopify.com/s/files/1/0775/7215/files/HMJ-MTG_WEB3.png?v=1763077032","https://cdn.shopify.com/s/files/1/0775/7215/files/HMJ-MTG_WEB4.png?v=1763077032","https://cdn.shopify.com/s/files/1/0775/7215/files/HMJ-MTG_WEB5.png?v=1763077032"],"price":160,"currency":"USD","in_stock":true,"inventory_qty":109989,"dynamic_pricing":false,"listed_at":"2026-06-20T14:55:46.414Z"},"share_url":"https://firestarter.network/l/lst_ncgfyol4","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
